SRW2048-K9-NA is a non-PoE, managed Gigabit switch with 48 copper access ports and four fixed Gigabit uplinks: two copper-only connections and two copper/SFP combo connections. The Cisco SG300-52 uses a full-width 1U chassis rather than a modular uplink bay, so its connection options do not depend on adding a network card. As part of the Small Business 300 family, the platform connects workstations, servers, printers, and separately powered network devices. Layer 2+ functionality supports segmented access networks with local forwarding between configured subnets. The discontinued SG300-52P-K9 differs by providing PoE+ on its powered access ports. This non-PoE configuration requires connected phones, access points, and other powered devices to obtain electricity separately.

104 Gbps switching capacity serves simultaneous traffic across the installed Gigabit interfaces. 77.38 Mpps forwarding capacity supports wire-speed handling of 64-byte packets. Static IPv4 routing provides inter-VLAN forwarding without dynamic route exchange, with limits of 32 static routes and 32 IP interfaces. SRW2048-K9-NA combines 128 MB of DRAM with 16 MB of flash for embedded software and configuration storage. Administrators can use the HTTP/HTTPS interface, serial console, SSH/Telnet access, or SNMP for configuration and monitoring. STP, RSTP, and MSTP control bridged paths, while four hardware queues support strict-priority or weighted round-robin scheduling. The Cisco 300 Series also supports IPv6 host operation and Multicast Listener Discovery snooping. Two fans require ventilated installation space; the operating range is 0°C to 40°C. Allow for a maximum power draw of 64.1W when sizing the switch's contribution to the rack power load.
Order SRW2048-K9-NA from ORM Systems in new sealed or certified refurbished condition, and specify the required condition, quantity, and accessory PIDs on the PO. Certified refurbished units are inspected and bench-tested for power-on and POST, rated-speed links on every port, clean boot, optics bay recognition, PSU status, and fan status; firmware is verified and configuration wiped to factory default. New units carry up to a 3-year extended warranty, certified refurbished units up to 1 year, and every condition has 30-day returns; terms apply. For enterprise and volume orders, PO acceptance, Net-30 for government, and RMA with advance replacement are available, with regional stock and RMA across the UK, EU, US, and MEA.

When consolidating several desktop switches into one connection point, count the server and upstream links that must be aggregated. The platform supports eight LACP groups with eight active ports per group. Specify the member-port allocation and confirm the connected equipment's aggregation settings before placing the PO.
When standardizing branch configurations across multiple sites, compare the active segment count with the limit of 256 simultaneous VLANs selected from 4096 VLAN IDs. A shared numbering plan does not remove that active-VLAN ceiling. Specify the per-site VLAN map and management addressing before ordering units for configuration staging.
When adding a switch to a troubleshooting lab, reserve a destination port for packet capture rather than treating every socket as an endpoint connection. Port mirroring accepts eight source ports in one session to one destination. Check the planned capture topology and reserve the analyzer connection before the PO.
10G fiber uplinks
Fixed uplinks stop at 1G, so this model cannot terminate 10G fiber links. C1300-48T-4X provides four 10G SFP+ uplinks with 48 Gigabit access ports.
PoE-powered phones or access points
RJ-45 ports supply no PoE, so powered endpoints need another electricity source. C1300-48P-4G is the PoE-capable alternative with 48 Gigabit access ports and four 1G SFP uplinks.
One logical hardware switch stack
The Small Business 300 family does not support hardware stacking. Multiple units remain independently managed switches; stacking cables cannot turn this model into a single logical chassis.

SRW2048-K9-NA identifies the regional ordering form of the SG300-52, a managed Gigabit switch in the Small Business 300 family. SRW2048-K9 identifies the hardware model, while -NA distinguishes its regional ordering form. The complete code denotes the non-PoE configuration rather than a separately ordered software license upgrade.
SRW2048-K9-NA is managed through its HTTP/HTTPS web interface, a CLI through the serial console or SSH/Telnet, and SNMP versions 1, 2c, and 3. Browser configuration covers setup, monitoring, and maintenance; SNMP supports network management tools. Select the management access method and authentication settings before configuration staging.
MGBSX1 and MGBLX1 are Gigabit SFP options for SRW2048-K9-NA, serving multimode and single-mode fiber respectively. The two SFP cages share their logical ports with RJ-45 connectors, so each combo port uses only one medium at a time. Specify the required optic PID and matching fiber connection on the order.
Yes, SRW2048-K9-NA supports static IPv4 routing between VLANs when configured in Layer 3 system mode. The routing limit is 32 static routes with 32 IP interfaces. Use Layer 2 mode for bridging only, and verify the intended system mode before loading the production configuration.
No, Small Business 300 switches do not form a hardware switch stack. Each unit retains its own management and configuration rather than acting as a shared chassis. Link aggregation connects interfaces, but does not combine separate units into one managed switch or provide a dedicated stacking backplane.
No, SRW2048-K9-NA has one internal universal AC supply rather than dual redundant power modules. The input range is 100–240V AC at 47–63 Hz. A second internal supply is not an ordering option for this model, so plan upstream power protection around a single chassis power input.
Yes, SRW2048-K9-NA is discontinued: Cisco sales ended October 4, 2018, and support ended October 31, 2023. Cisco service is no longer available for this hardware. C1300-48T-4G is the endpoint of the replacement chain; the intervening SG350 and CBS350 generations are also discontinued.
SRW2048-K9-NA replaces SRW2048, the earlier 48-port Gigabit switch with WebView. The replacement carries the SG300-52 model name and provides 48 access connections plus four special-purpose Gigabit connections. Treat the transition as a hardware replacement, and review the management configuration and uplink connections before scheduling the change.
SG300-52P-K9 supplies PoE+ on 48 ports with a shared 375W budget, while SRW2048-K9-NA supplies no endpoint power. Both belong to the discontinued Small Business 300 family. The powered version addresses legacy endpoint-power requirements; the non-PoE model suits existing equipment that already has separate power.
SRW2048-K9-NA provides 48 Gigabit access ports, compared with 24 on SRW2024-K9; both add four special-purpose Gigabit ports. Both models are discontinued. The higher-density unit suits a larger existing connection count, while the smaller model addresses legacy configurations with fewer endpoint connections to terminate.
C1300-48T-4G has four dedicated 1G SFP uplinks, whereas SRW2048-K9-NA has two copper-only uplinks plus two shared copper/SFP combo uplinks. The newer model separates fiber uplinks from its 48 Gigabit access ports. C1300-48T-4G suits replacement projects; the older model serves matching legacy installations.
Yes, Cisco SG300-52 is a full-width 1U rack-mount switch with a 440 mm chassis width. The enclosure is 44.45 mm high and 257 mm deep, with a 3.91 kg unit weight. Confirm rack depth, cable clearance, and the mounting-kit contents when specifying the order.
ORM Systems offers SRW2048-K9-NA new sealed or certified refurbished, with up to a 3-year extended warranty on new units and up to 1 year on refurbished units. Returns are available for 30 days on every condition; terms apply. Cisco's limited lifetime hardware warranty and service ended October 31, 2023.
