CBS250-48P-4G is a smart managed Layer 2+ access switch with 48 fixed 10/100/1000 PoE+ copper ports, four fixed 1G SFP uplinks and a rack-mount 1U chassis. The Cisco Business 250 Series model serves small business wiring closets, retail back offices and branch access layers where endpoint power and local VLAN routing are needed without a modular uplink bay. A 370W shared PoE budget supports phones, cameras and access points across the Gigabit ports, while static IPv4 routing keeps limited inter-VLAN paths on the access switch. Compared with CBS250-48PP-4G, the 48-port Gigabit PoE+ access switch keeps the same four 1G SFP uplinks but raises the PoE budget from 195W to 370W.
CBS250-48P-4G price for new stock is $1,025.85, a 29.3% saving from the Cisco list price of $1,451.25. CBS250-48P-4G refurb price is $471.45. CBS250-48P-4G is in stock and available for next-day dispatch. (terms applied)

104 Gbps switching capacity and 77.38 Mpps forwarding support wire-speed nonblocking operation across the copper and fiber ports. 370W PoE power is shared across 48 PoE+ ports, with up to 30W available to any one port until the budget is reached. CBS250-48P-4G supports Layer 2 controls including STP, RSTP, MSTP, LACP, 255 active VLANs, 8 hardware QoS queues, IGMP snooping and IGMP querier. Static IPv4 routing supports up to 32 routes and 16 IP interfaces, with IPv6 routing, DHCP relay and UDP relay for small routed edges. The Cisco Business 250 Series Smart Switches management set includes Cisco Business Dashboard, Cisco Business mobile app, HTTP/HTTPS web UI, SNMP, CLI, SSH and Telnet. An 8K MAC table, 512 MB DRAM, 256 MB flash and a 3 MB packet buffer support the smart switching image; stacking and modular uplink cards are absent.
CBS250-48P-4G can be supplied new sealed or certified refurbished, with the regional orderable variant matched to the destination country. Certified refurbished units are inspected and bench-tested; managed units are firmware verified, wiped to factory default, checked for power-on and POST, linked on every port, loaded for PoE output, and verified for SFP bay, PSU and fan status. Specify condition and regional stock location on the purchase order. ORM Systems accepts PO terms, Net-30 for government, RMA with advance replacement and UK, EU, US or MEA stock/RMA planning; new units carry up to 3-year extended warranty, certified refurbished units up to 1 year, and returns are 30 days on every condition, terms apply.

A small business wiring closet with phones, cameras and access points can consolidate 48 1G copper drops on one smart managed switch. The shared 370W PoE budget, 48 PoE+ ports and four 1G SFP uplinks define the endpoint power worksheet and fiber handoff before the PO.
A branch that only needs local inter-VLAN routing can keep simple Layer 3 paths at the access layer. Static IPv4 routing supports up to 32 routes and 16 IP interfaces, so specify this model only after counting routed VLANs, relay needs and upstream default routes.
A retail or branch rollout using Cisco Business Dashboard and Cisco Business mobile app can standardize configuration handling across locations without adding a separate dashboard probe. The embedded probe, HTTP/HTTPS web UI, SNMP and CLI access should be matched to the management process before staging.
10G fiber uplinks
Four fixed uplinks are 1G SFP on this model; the current C1200-48P-4X moves the same 48-port PoE access role to four 10G SFP+ uplinks.
All-port maximum PoE
370W is shared across 48 PoE+ ports, while 48 ports at 30W would require 1440W before switch overhead; size high-draw endpoint counts separately.
Hardware stacking
Business 250 hardware has no stacking ports, stacking kit, stack bandwidth or member limit; use a stackable access platform when one control plane must span switches.
Redundant power supplies
Power is a fixed internal AC supply with no redundant PSU bay; deployments requiring supply redundancy need a platform that ships with or accepts redundant power.

CBS250-48P-4G identifies a Cisco Business 250 smart switch with 48 Gigabit Ethernet PoE ports and four 1G SFP uplinks. The orderable hardware PID adds a country suffix; CBS250-48P-4G-NA is the United States variant, while other regions use their own suffixes.
CBS250-48P-4G is managed through Cisco Business Dashboard, Cisco Business mobile app, HTTP/HTTPS web UI, SNMP and CLI access. CLI access includes SSH and Telnet support, and the platform also supports an embedded dashboard probe for sites that do not run a separate probe.
Yes, CBS250-48P-4G-NA passed end-of-sale on 29 October 2024. Cisco service and support continue until 31 October 2029 for entitled hardware, and C1200-48P-4G is the named migration product for the same 48-port GE PoE, 4x1G SFP role.
ORM Systems offers CBS250-48P-4G new sealed or certified refurbished. Cisco lists a limited lifetime hardware warranty with service ending 31 October 2029; ORM offers up to 3-year extended warranty on new units and up to 1 year on certified refurbished units, with 30-day returns, terms apply.
No, CBS250-48P-4G does not require a separate software subscription line on the hardware order. The purchase order should carry the country-specific hardware PID, the intended condition and any required cabling or SFP modules rather than a Network Essentials or DNA license.
CBS250-48P-4G-NA was named as the replacement for SG250-50P-K9-NA in the 50-port Gigabit PoE Smart Switch refresh path. That mapping matters when a buyer is replacing an SG250-50P-K9-NA and wants the closest Cisco Business 250 configuration.
CBS250-48P-4G provides a 370W PoE budget across 48 PoE+ ports. Any single Gigabit Ethernet port can deliver up to 30W until the shared budget is reached, so 48 fully loaded 30W endpoints exceed the available PoE budget.
CBS250-48P-4G uses 1G SFP uplinks and supports MGBSX1, MGBLH1, MGBLX1, MGBT1, GLC-SX-MMD, GLC-LH-SMD, GLC-BX-U, GLC-BX-D and GLC-TE. SFP-H10GB-CU1M, SFP-H10GB-CU3M, SFP-H10GB-CU5M, SFP-10G-SR, SFP-10G-LR, SFP-10G-SR-S and SFP-10G-LR-S are for SFP+ models.
Cisco Business 250 can route limited traffic between VLANs using static IPv4 routing. The platform supports up to 32 static IPv4 routes and 16 IP interfaces, plus IPv6 routing, DHCP relay and UDP relay; buyers needing dynamic routed access should choose another platform.
Yes, CBS250-48P-4G is a rack-mount 1U switch with 445 mm width, 350 mm depth and 44 mm height. The package includes a mounting kit and power cord, and the switch uses an internal 100-240V AC, 50-60 Hz power input.
CBS250-48P-4G provides a 370W PoE budget, while CBS250-48PP-4G provides a 195W PoE budget. Both models have 48 10/100/1000 PoE+ ports and four 1G SFP uplinks; CBS250-48P-4G fits higher aggregate endpoint draw, while CBS250-48PP-4G fits lower PoE totals.
CBS250-48P-4X carries four 10G SFP+ uplinks where CBS250-48P-4G carries four 1G SFP uplinks. Both models keep 48 10/100/1000 PoE+ ports with a 370W budget, so CBS250-48P-4G fits 1G aggregation and CBS250-48P-4X fits 10G uplink handoffs.
C1200-48P-4G is the named migration product and provides a 375W PoE budget, while CBS250-48P-4G provides 370W. Both are 48-port GE PoE switches with four 1G SFP uplinks; C1200-48P-4G fits current standardization, while CBS250-48P-4G fits Business 250 spares.
