SRW248G4P-K9 provides managed Fast Ethernet access with PoE for 48 copper endpoints, rather than Gigabit access connections. This Layer 2+ switch combines a rack-mounted chassis with fixed Gigabit uplinks: two dedicated copper connections and two copper/SFP combo connections, with one medium active per combo connection. Cisco SF300-48P belongs to the Small Business 300 family and supports data, voice, security, and wireless connectivity within its endpoint speed and power limits. The discontinued SRW248G4-K9 is the nearest non-PoE sibling for installations where endpoints receive power separately. The fixed uplink architecture allows copper or fiber connections without an expansion card, but does not provide a removable network-module bay.

17.6 Gbps switching capacity supports traffic across the access and uplink interfaces. 13.1 Mpps forwarding handles 64-byte packets at the published forwarding rate. A 375W shared PoE budget supplies compatible endpoints, with 15.4W available per powered port subject to the total allocation. Static IPv4 routing provides inter-subnet forwarding; dynamic routing is not part of the stated routing feature set. SRW248G4P-K9 carries 128 MB of memory and 16 MB of flash for its embedded management functions and configuration storage. An 8000-entry MAC table accommodates learned endpoint addresses. STP/RSTP/MSTP provide spanning-tree operation, while LACP supports link aggregation. Four hardware queues use strict-priority or weighted round-robin scheduling to handle traffic classes. Browser-based HTTP/HTTPS management and SNMP monitoring support configuration and operational checks. Three speed-controlled fans provide active cooling, so this model is not fanless.
ORM Systems supplies SRW248G4P-K9 new sealed or certified refurbished, with up to a 3-year extended warranty on new units and up to a 1-year warranty on certified refurbished units; every condition includes 30-day returns, with terms applying. Certified refurbished units are inspected and bench-tested, with PoE output verified under load on every powered port, firmware verified, and configuration wiped to factory default. Specify the condition, quantity, and regional delivery requirements on the purchase order. PO accepted, Net-30 for government, and RMA with advance replacement support enterprise and volume orders across the UK, EU, US, and MEA.

When several locations need a repeatable configuration, the switch supports text-editable configuration files that can be downloaded to another unit. That capability separates configuration preparation from physical installation and allows the same settings to be reviewed before rollout. Specify the required configuration baseline and staging procedure before the purchase order.
When a troubleshooting or staging bench needs visibility into endpoint traffic, port mirroring supports eight source ports feeding one destination port in a single session. The destination connection must be reserved for the analyzer rather than another endpoint. Identify the monitored connections and analyzer attachment before ordering the staging hardware.
When a branch requires local subnet interfaces, the switch supports 32 IP interfaces for its static IPv4 routing configuration. Interface planning remains separate from the endpoint connection count and should include the intended subnet boundaries. Check the required interface count and prepare the addressing plan before specifying the unit on the purchase order.
Gigabit speed on every access port
The 48 access connections operate at 10/100 Mbps, not Gigabit speed. C1300-48P-4G is the current replacement-chain model with 48 Gigabit access connections.
30W power on each endpoint connection
Powered access connections support 15.4W per port under the shared budget. Endpoints requiring 30W from a PoE+ connection exceed this model's per-port power capability.
10G uplinks to upstream equipment
The fixed uplinks operate at Gigabit speed. The chassis has no removable uplink expansion card, so a different switch is required when the upstream connection must operate at 10G.

SRW248G4P-K9 identifies Cisco SF300-48P, a managed Small Business 300 switch with 48 Fast Ethernet PoE access connections and four Gigabit uplinks. Two uplinks are dedicated copper connections, while two are copper/SFP combo connections. The access ports provide standard PoE rather than PoE+.
SRW248G4P-K9 supports browser-based management over HTTP/HTTPS, SSH/Telnet access, and SNMP monitoring. The management functions include configuration, maintenance, and operational monitoring. SNMP versions 1, 2c, and 3 are supported, with the version 3 user-based security model available for authenticated management access.
SRW248G4P-K9 reached end of sale on April 27, 2015, and its last date of support was April 30, 2020. Cisco service has ended for this legacy model. A new sealed unit is remaining inventory, not a product that can still be ordered from Cisco.
ORM Systems offers SRW248G4P-K9 new sealed with up to a 3-year extended warranty, or certified refurbished with up to a 1-year warranty. Every condition has 30-day returns; terms apply. Cisco's original platform warranty was Limited Lifetime, while Cisco service ended April 30, 2020. ORM's warranty is separate.
SRW248G4P-K9 provides a shared 375W PoE budget across 48 powered access ports, with 15.4W available per port subject to that total. Running every powered port at its maximum would require 48 x 15.4W = 739.2W. Size the endpoint allocation against the shared budget before ordering.
Cisco SF300-48P supports Gigabit fiber transceivers including MGBSX1 for multimode fiber and MGBLX1 for single-mode fiber. The SFP cages belong to combo uplinks shared with copper connections. Specify the transceiver PID, fiber medium, and remote connection requirements rather than assuming that any SFP will be compatible.
Yes, SRW248G4P-K9 supports static IPv4 routing between subnets, with 32 static routes and 32 IP interfaces in the retrieved hardware specification. Its routing capability is static rather than a dynamic routing feature set. Confirm that the intended subnet and route counts fit before using the switch for local routing.
Yes, Cisco SF300-48P has a full-width rack-mount chassis measuring 440 mm wide, 44.45 mm high, and 350 mm deep. The unit weighs 5.87 kg. Check rack depth, mounting hardware, and clearance for cabling before the purchase order, particularly when replacing a shallower non-PoE unit.
SRW248G4P-K9 provides PoE on its access connections, whereas SRW248G4-K9 does not supply endpoint power. Both are discontinued Small Business 300 models. The powered model suits legacy installations with compatible PoE endpoints; the non-PoE model suits legacy connections where devices receive power from a separate source.
SRW248G4P-K9 has 48 Fast Ethernet access connections, while SRW224G4P-K9 has 24. Both are discontinued managed models with Gigabit uplinks. The larger unit suits legacy installations requiring the higher endpoint count; the smaller unit suits legacy installations whose access connection requirement fits within 24 ports.
SRW248G4P-K9 has 10/100 Mbps access connections, while C1300-48P-4G has Gigabit access connections. The older model is discontinued, and C1300-48P-4G is the current model at the end of its replacement chain. The legacy unit suits like-for-like sparing; the current model suits a Gigabit access refresh.
C1300-48P-4G is the current switch at the end of the SRW248G4P-K9 replacement chain. The immediate successor SF300-48PP-K9-NA is discontinued, followed by discontinued SF350-48P-K9-NA and CBS350-48P-4G-NA. The final model retains 48 access connections but changes their native speed from Fast Ethernet to Gigabit Ethernet.
Cisco SF300-48P has a published worst-case consumption of 473.5W at 110V AC and 456.8W at 220V AC. Those figures include the powered operating condition rather than just the endpoint PoE budget. Use the applicable input-voltage figure when planning the electrical circuit and upstream power capacity.
No, SRW248G4P-K9 uses three fans with speed control rather than passive cooling. The operating temperature range is 0°C to 40°C, and the published MTBF is 182540 hours at 40°C. Keep the cooling arrangement and ambient temperature requirement in view when specifying placement for this model.
