ASR-920-PWR-A Overview

ASR-920-PWR-A is the Cisco ASR920 AC Power Supply designed for Cisco ASR-920-24SZ-IM, ASR-920-24SZ-M, and ASR-920-24TZ-M routers. It is a hot-swappable modular router power supply installed in ASR 920 power bays, not a complete router, power cord, fan tray, blank cover, cable, external adapter, transceiver, firewall, storage device, memory item, or wireless product. Cisco places ASR-920-PWR-D alongside it within the same field-replaceable power family; that sibling differs by using DC input rather than AC input. The module is relevant when a supported ASR 920 chassis requires an AC power bay to be populated, a matching redundant supply, or a direct replacement for an installed AC PSU. This positioning helps purchasing and maintenance teams distinguish the module from other ASR 920 service parts and select the correct input type for the deployed chassis. It also keeps AC and DC replacement inventories clearly separated when support teams maintain multiple ASR 920 sites with different facility power arrangements.

A 250 W maximum power specification supports the modular ASR 920 power shelf used in the named router models. The AC side is defined by 260 W input power, 100 to 240 VAC service, 50/60 Hz frequency, and 2.6 A draw through a standard C16 receptacle. PSU LED status reflects the 12V output condition: the LED turns green when output remains within the supported range and red when input power is absent or the unit has a fault. ASR-920-PWR-A supports 1+1 redundant router power with load sharing when both supplies are installed and powered. Cisco hardware guidance also documents hot-swap servicing when redundant power supplies are present, together with a minimum reinitialization wait after removal or replacement. These operating details are important when technicians plan maintenance without unnecessarily interrupting router service or compromising the intended redundant power arrangement.

ASR-920-PWR-A fits edge and aggregation-router maintenance programs where the chassis model, AC branch circuit, C16 power path, and second-supply strategy have already been verified. Each chassis power supply should use its own dedicated branch circuit, while AC installations require building-provided surge protection as part of the service equipment. ORM Systems supplies this power supply in new and certified refurbished condition. Refurbished units are checked through output-voltage and ripple verification under load, LED status review, connector inspection, and latch or captive-screw inspection before dispatch. Buyers can send the target ASR 920 model and required quantity to ORM Systems for a quote or standardize spare shelves around this exact PSU PID for multi-site ASR 920 support. Recording the precise model compatibility, AC input requirements, C16 receptacle, and redundancy plan alongside the spare PID helps maintain consistent procurement and replacement practices across supported deployments.

ASR-920-PWR-A Use Case

ASR 920 Edge Router PSU Replacement

ASR-920-PWR-A sits in the modular power bay of supported Cisco ASR-920-24SZ-IM, ASR-920-24SZ-M, and ASR-920-24TZ-M routers during planned AC PSU replacement. Field teams verify the installed PID, chassis grounding, C16 input path, and captive screw before seating the module. The AC supply feeds the router power shelf through the internal bay, while the front PSU LED confirms output state after activation. The edge router returns to a documented power configuration with the correct AC module and no DC substitute. The service record also retains branch-circuit and LED evidence.

Redundant Aggregation Router Power Bays

A dual-supply ASR 920 aggregation router uses ASR-920-PWR-A when the site power plan calls for AC input and 1+1 PSU population. Each supply connects to an appropriate branch circuit, and both inserted PSUs share load while powered. Network operations record the C16 receptacle, 2.6 A current figure, retainer-clip handling, and green LED check in the maintenance plan. The router gains cleaner redundancy documentation and simpler field replacement decisions for AC-powered access aggregation nodes. Spare records remain tied to the same input type and chassis group.

Multi-Site ASR Spare Pool Control

ASR 920 fleet spares stay more accurate when AC, DC, and higher-power PSU families are separated by exact Cisco PID. This module belongs in bins for supported high-port-density ASR 920 chassis rather than ASR-920-PWR-D or A920-PWR400-A inventory. Asset staff record the 250 W class, 260 W input detail, C16 receptacle, and compatible router models beside the spare record. The spare pool gains fewer dispatch mismatches and faster receiving checks during regional router maintenance. Purchasing also avoids unsupported swaps between AC and DC field units.

Questions & Answers

What is ASR-920-PWR-A?

ASR-920-PWR-A is a Cisco ASR920 AC Power Supply for supported ASR 920 aggregation router chassis. It is a modular router PSU for the power-supply bays, not a router chassis, cable, fan tray, blank cover, transceiver, adapter, firewall, storage device, memory product, or wireless item. The exact PID should be preserved in product records.

What hardware type is ASR-920-PWR-A?

ASR-920-PWR-A is a router power supply module. It belongs in the power-supply category because Cisco identifies it as an ASR920 AC Power Supply and documents the AC PSU specification for the ASR 920 modular router models. It should not be classified as a standalone router or as a power cord.

Where does ASR-920-PWR-A sit in the Cisco ASR 920 lineup?

ASR-920-PWR-A sits in the Cisco ASR 920 power-supply family used by the high-port-density ASR 920 modular and fixed router models. Cisco lists it beside ASR-920-PWR-D, the DC version. The AC PID serves deployments that use AC branch circuits and C16 power connections in the supported chassis.

What does the ASR-920-PWR-A model number mean?

ASR-920-PWR-A identifies a Cisco ASR 920 power module, with PWR indicating power supply and A indicating the AC version. The exact string matters because Cisco also lists ASR-920-PWR-D for DC input and regional power-cord PIDs separately. Spreadsheet and ecommerce systems should store the SKU as text.

What wattage should be listed for ASR-920-PWR-A?

ASR-920-PWR-A should use 250W as the wattage token because the ASR 920 hardware guide lists the AC power-supply power specification as 250 W maximum for the supported router models. The same source also lists 260 W input power, which belongs in Power Details rather than replacing the wattage field.

What input voltage does ASR-920-PWR-A use?

ASR-920-PWR-A uses AC input rated at 100 to 240 VAC with 50/60 Hz frequency support in the Cisco ASR 920 installation guide. The same table lists 2.6 A current through a standard C16 type receptacle. AC branch circuit sizing and local electrical code should be reviewed during installation planning.

What output voltage is documented for ASR-920-PWR-A?

The Cisco ASR 920 guide ties the PSU status LED to 12V output condition, so the specification can use 12VDC for ASR-920-PWR-A. The source does not provide a customer-facing output connector because the module feeds the router power bay internally. External outlet or UPS-style output claims should be excluded.

What form factor does ASR-920-PWR-A use?

ASR-920-PWR-A uses a hot-plug module form factor for the power-supply bay in supported Cisco ASR 920 router models. The installation guide describes sliding the AC power supply into the bay and tightening the captive installation screw. It is not an external adapter or fixed cord assembly.

Is ASR-920-PWR-A hot-swappable?

ASR-920-PWR-A is hot-swappable in the supported ASR 920 router context when redundant power supplies are installed. Cisco states that a single power supply can be replaced without interrupting power to the router in that redundant condition. The guide also recommends allowing at least two minutes for reinitialization after replacement.

Does ASR-920-PWR-A support redundant power?

ASR-920-PWR-A supports 1+1 redundant power operation in Cisco ASR-920-24SZ-IM, ASR-920-24SZ-M, and ASR-920-24TZ-M routers. Cisco documents load sharing when both PSUs are inserted and powered. If one supply is not working or its input cable is removed, the remaining supply takes the load. This supports service planning around matched AC bays.

Which Cisco routers are compatible with ASR-920-PWR-A?

ASR-920-PWR-A is tied to Cisco ASR-920-24SZ-IM, ASR-920-24SZ-M, and ASR-920-24TZ-M routers in the Cisco ASR 920 high-port-density hardware guide. Compatibility should not be expanded to other ASR, Catalyst, ISR, server, firewall, or wireless platforms unless an exact manufacturer source names that PID. Keep the compatibility list narrow.

Does ASR-920-PWR-A fit the ASR-920-24SZ-IM?

ASR-920-PWR-A fits the ASR-920-24SZ-IM power-supply context documented by Cisco for the ASR 920 modular router family. The hardware guide lists the AC PSU values, redundant operation, hot-swap handling, and front-panel PSU LED behavior for that router group. The target chassis should still be verified before ordering.

Does ASR-920-PWR-A fit ASR-920-24SZ-M and ASR-920-24TZ-M routers?

ASR-920-PWR-A is documented with the ASR-920-24SZ-M and ASR-920-24TZ-M router power system in Cisco's hardware guide. Those fixed high-port-density models support redundant modular AC or DC power supplies. Buyers should confirm the installed PSU type and the second-bay plan before selecting an AC replacement. The installed label remains the final receiving check.

What AC connector should be planned for ASR-920-PWR-A?

ASR-920-PWR-A uses the AC supply path documented with a standard C16 type receptacle and a 15A service connector. Cisco also notes that the AC supply has a power cord retainer clip for straight power cords. Regional cord choice should come from the separate supported power-cord PID list.

Does ASR-920-PWR-A include a power cord?

The core ASR-920-PWR-A record should not invent an included regional power cord. Cisco lists power-cord PIDs separately for regions such as the US, UK, Europe, Australia, India, and others. The included component that belongs with the PSU itself is the power supply module with its retainer clip.

How does ASR-920-PWR-A compare with ASR-920-PWR-D?

ASR-920-PWR-A is the AC version, while ASR-920-PWR-D is the DC version for the same ASR 920 power-supply family. The AC module uses 100 to 240 VAC and a C16 receptacle. The DC module uses -48/-60 V or 24 V input through a two-position terminal block.

How does ASR-920-PWR-A compare with A920-PWR400-A?

ASR-920-PWR-A is the 250 W class AC PSU for Cisco ASR-920-24SZ-IM, ASR-920-24SZ-M, and ASR-920-24TZ-M router models. A920-PWR400-A is a different Cisco ASR 920 AC PSU entry associated with the higher-power ASR-920-12SZ-IM platform. Compatibility and wattage should stay bound to each PID. Mixing them creates an unsupported row.

How does ASR-920-PWR-A compare with A920-PWR400-D?

ASR-920-PWR-A is an AC module for the ASR 920 modular power bays, while A920-PWR400-D is a DC PSU entry from another ASR 920 power-supply tier. The difference is not only input type; the associated router platform and power rating also differ, so the PIDs should not be substituted.

How does ASR-920-PWR-A compare with ASR-920-PWR-A=?

ASR-920-PWR-A is the non-equals PID, while ASR-920-PWR-A= is the spare-style form that includes a trailing equals sign. Cisco PID punctuation is meaningful, so the exact version provided by the buyer should be preserved. Electrical content should still be checked against the same ASR 920 AC supply facts.

Is ASR-920-PWR-A a replacement for a failed ASR 920 AC PSU?

ASR-920-PWR-A is suitable for like-for-like replacement when the installed module is the same Cisco ASR 920 AC PSU PID and the host router is a supported ASR-920-24SZ-IM, ASR-920-24SZ-M, or ASR-920-24TZ-M chassis. The existing part label and power bay should be checked before dispatch. Condition should also be confirmed.

What environments use ASR-920-PWR-A?

ASR-920-PWR-A is used in ASR 920 edge and aggregation-router locations where AC power feeds support modular redundant power bays. Typical planning points include C16 receptacle access, dedicated branch circuits, second-supply population, front-panel PSU LED checks, and spare inventory organized by exact Cisco PID rather than broad ASR family labels.

Is ASR-920-PWR-A suitable for redundant ASR 920 deployments?

ASR-920-PWR-A is suitable for redundant ASR 920 power plans when the target chassis supports two modular power supplies and the second bay uses a compatible power source. Cisco documents 1+1 redundancy and load sharing for the supported router models. Each supply should connect to an appropriate, separate input source.

Is ASR-920-PWR-A used for fixed low-density ASR 920 routers?

ASR-920-PWR-A should not be automatically assigned to fixed low-density ASR 920 models. Cisco documentation separates built-in low-density power supplies from modular high-port-density models and names different power specifications. The safe compatibility record for this SKU is ASR-920-24SZ-IM, ASR-920-24SZ-M, and ASR-920-24TZ-M. Other models need their own source.

Does ASR-920-PWR-A require configuration after installation?

ASR-920-PWR-A does not require a software license or feature configuration as a power-supply module. Installation work centers on chassis grounding, bay seating, captive-screw tightening, AC cord retention, branch-circuit connection, and LED verification. Router management may report PSU state, but the PSU itself is not configured like an interface module.

What should be checked before buying ASR-920-PWR-A?

Before buying ASR-920-PWR-A, the buyer should verify the exact ASR 920 chassis model, existing PSU label, AC input requirement, power-bay population, redundant supply plan, C16 receptacle path, and regional cord requirement. These checks prevent substitution with ASR-920-PWR-D, A920-PWR400-A, power cords, blank covers, or unrelated router accessories.

Can ASR-920-PWR-A be purchased refurbished?

ASR-920-PWR-A can be sourced in certified refurbished condition through ORM Systems when available for the requested quantity and condition. Refurbished PSU content should focus on verified electrical checks, connector condition, LED status, and physical fit. It should not invent remaining service life, factory-new status, warranty duration, or lead time.

Can ASR-920-PWR-A be purchased new?

ASR-920-PWR-A can be requested in new condition through ORM Systems, subject to quote confirmation and channel availability at the time of purchase. The product page should avoid unsupported stock or shipping promises. Buyers needing unused units should state condition, quantity, destination, and target router model during the quote request.

How is price handled for ASR-920-PWR-A?

ASR-920-PWR-A pricing should be handled through a quote because condition, quantity, sourcing route, and refurbishment status can affect the commercial offer. Product content should not copy marketplace prices or invent savings. A quote request lets ORM Systems confirm the exact Cisco PID, availability, condition, and quantity before purchase.

Are bulk orders available for ASR-920-PWR-A?

Bulk requests for ASR-920-PWR-A should be reviewed as a quote rather than assumed from a public stock figure. Multi-site ASR 920 fleets often need matching AC PSU spares, but quantity, condition, and sourcing must be verified. Product content should not promise discounts unless business data explicitly provides that offer.

What lead time should be shown for ASR-920-PWR-A?

Lead time for ASR-920-PWR-A should not be invented in the product content. Availability and dispatch timing should be confirmed during the ORM Systems quote process based on quantity, condition, destination, and current sourcing. This keeps the page accurate while still supporting buyers who need planned ASR 920 spare-pool replenishment.

What testing should refurbished ASR-920-PWR-A units receive?

Refurbished ASR-920-PWR-A units should be checked with power-specific receiving and bench procedures before dispatch. Useful checks include output-voltage and ripple behavior under load, status LED response, connector and C16 inlet condition, captive-screw or latch inspection, and physical seating review. Unsupported claims about untouched condition should be avoided.

What certifications apply to ASR-920-PWR-A?

ASR-920-PWR-A is covered under the Cisco ASR 920 documentation that lists safety, EMC, NEBS, and ETSI compliance references for the router family. The product record can cite standards such as UL 60950-1, FCC CFR47 Part 15 Class A, GR-63-CORE, and GR-1089-CORE where applicable to the documented platform.

Does ASR-920-PWR-A require a UPS or PDU specification?

ASR-920-PWR-A is not a UPS, PDU, or battery module, so UPS capacity, battery runtime, and output outlets should remain N/A in the specification schema. The module accepts AC input for a supported router power bay. Any site UPS or PDU belongs to the facility design, not this SKU.

Where can buyers source ASR-920-PWR-A in the UK?

Buyers can source ASR-920-PWR-A through ORM Systems by requesting a quote with the exact Cisco PID, required condition, quantity, and destination. The quote process should confirm compatibility with ASR-920-24SZ-IM, ASR-920-24SZ-M, or ASR-920-24TZ-M and avoid unsupported assumptions about stock or delivery timing. Exact condition should be stated clearly.

Does ORM Systems ship ASR-920-PWR-A internationally?

International handling for ASR-920-PWR-A should be confirmed during the ORM Systems quote process because destination, customs requirements, condition, and quantity affect fulfillment. The product data should preserve the exact SKU and regional cord needs without inventing delivery speed. Buyers should share the target ASR 920 chassis and location.
