CBS350-48T-4G is a 48-port Gigabit managed switch for SMB access layers that need copper endpoint connectivity without PoE. The Cisco Business 350 managed switch provides Layer 2+ switching with 48 10/100/1000 RJ-45 access ports and four fixed 1G SFP uplinks for fiber handoff to an upstream switch or router. Its 1U rack form factor fits wiring closets where a small office network needs browser, CLI, dashboard, app, and SNMP management without a separate software license tier. The 48-port Gigabit access switch with fixed SFP uplinks is non-PoE, so phones, cameras, and access points need local power or a powered access model. CBS350-48P-4G keeps the same 48-port and 4x1G SFP layout but adds PoE+ with a 370W budget.
CBS350-48T-4G price for new stock is $1,207.50, a 22.2% saving from the Cisco list price of $1,552.50. CBS350-48T-4G refurb price is $766.50. CBS350-48T-4G is in stock and available for next-day dispatch. (terms applied)

104 Gbps switching capacity and 77.38 Mpps forwarding support wire-speed traffic across the copper access ports and fixed Gigabit SFP uplinks. Static IPv4 routing up to 990 routes, RIP v2, PBR, IPv6 routing, and 128 IP interfaces let the Business 350 Series handle routed VLAN boundaries at the SMB edge. CBS350-48T-4G carries 512 MB DRAM, 256 MB flash, a 16000-entry MAC table, and a 3 MB shared packet buffer. STP, RSTP, MSTP, LACP, 4094 VLAN support, IGMP snooping, IGMP proxy, DHCP snooping, IP Source Guard, Dynamic ARP Inspection, RADIUS, TACACS+, SSH, and SSL are available in the managed firmware. Hardware stacking is absent on this 4G model; the true-stacking list starts with selected 4X, multigigabit, and 10 Gigabit Business 350 switches.
Order CBS350-48T-4G new sealed or certified refurbished, matched to the regional suffix and any required 1G SFP transceivers. Refurbished managed units are inspected and bench-tested for power-on and POST, every port linking at rated speed, optics bay recognition, fan status, firmware verification, and configuration wiped to factory default. New units are eligible for up to a 3-year extended ORM warranty, certified refurbished units for up to 1 year, and every condition has 30-day returns, terms apply. PO is accepted, Net-30 is available for government, RMA with advance replacement is supported, and regional stock/RMA coverage spans UK, EU, US, and MEA.

A branch refresh with existing 1G copper endpoints can consolidate two smaller access switches into one 1U unit with 48 access ports and four SFP uplinks. Confirm fiber reach and transceiver PIDs before the PO, because the base switch includes the cages, not optics.
A small office that routes between voice, guest, and data VLANs can use static IPv4 routes up to 990 entries, RIP v2, PBR, and 128 IP interfaces. Validate the routing design against those limits before specifying the switch for inter-VLAN traffic.
A site already standardized on Cisco Business 350 hardware can keep a like-for-like spare for 48-port non-PoE access closets after Cisco end-of-sale. Match the regional suffix, rack kit expectations, and SFP optic PIDs so the spare fits the existing cabling plan.
PoE endpoint power
CBS350-48T-4G has non-PoE RJ-45 access ports. If the purchase must power phones or access points, C1300-48P-4G is the migration-family alternative with 48-port PoE.
10G uplinks to distribution
CBS350-48T-4G uses four 1G SFP uplinks. If aggregation requires 10G SFP+, C1300-48T-4X is the migration-family alternative with four 10G SFP+ uplinks.
Hardware stack control
CBS350-48T-4G is not in the hardware-stacking model list. Do not use this PID where a single control plane across multiple switches is mandatory.

CBS350-48T-4G is a Cisco Business 350 managed switch with 48 10/100/1000 RJ-45 access ports and 4 fixed Gigabit SFP uplinks. It is a rack-mount Layer 2+ model for SMB wired access where endpoint power is not required, with 104 Gbps switching capacity.
CBS350-48T-4G identifies the Business 350 family, a 48-port 10/100/1000 non-PoE copper configuration, and 4 Gigabit SFP uplinks. Cisco orders the hardware with a country or region suffix; for the U.S. region the complete PID is CBS350-48T-4G-NA.
CBS350-48T-4G is managed through the web UI over HTTP or HTTPS, Cisco Business Dashboard, Cisco Business mobile app, full CLI Text view, SNMP, and SSH. The software also supports Telnet server/SSH for IPv6 applications, plus RADIUS and TACACS+ for administrator authentication.
CBS350-48T-4G is end-of-sale, with Cisco's last order date on 29 October 2024 and last date of support on 31 October 2029. Cisco named C1300-48T-4G as the migration PID for the regional CBS350-48T-4G variants.
CBS350-48T-4G is available from ORM Systems new sealed or certified refurbished. Cisco's platform warranty is Limited Lifetime with next-business-day advance replacement where available until Cisco service ends 31 October 2029; ORM offers up to 3-year extended warranty on new units, up to 1 year on refurbished units, and 30-day returns, terms apply.
CBS350-48T-4G does not require a separate software license tier or subscription in the product order. The managed feature set is part of the switch firmware, so the purchase order should specify the regional hardware PID, optics if needed, condition, and support terms.
CBS350-48T-4G replaced SF350-48-K9-NA and SG350-52-K9-NA for U.S. regional ordering. SF350-48-K9-NA reached end of sale on 30 July 2022, while SG350-52-K9-NA reached end of sale on 30 October 2021. Both map to the 48-port GE, 4x1G SFP CBS350 configuration.
CBS350-48T-4G is non-PoE and does not deliver endpoint power on its 48 RJ-45 ports. Buyers powering phones, cameras, or access points should use a PoE model such as C1300-48P-4G, which is named as the migration-family 48-port GE PoE alternative.
CBS350-48T-4G has 4 fixed 1G SFP uplinks, not SFP+ uplinks. Supported 1G transceiver PIDs include MGBSX1, MGBLX1, MGBLH1, MGBT1, GLC-SX-MMD, GLC-LH-SMD, GLC-BX-U, GLC-BX-D, and GLC-TE; optics are separate from the base switch.
CBS350-48T-4G cannot be hardware-stacked. Hardware stacking is limited to specific CBS350 4X, multigigabit, and 10 Gigabit models, with up to 4 units and 200 ports in a stack; the 48T-4G model is not in that supported list.
CBS350-48T-4G supports Layer 2+ routing with static IPv4 routes up to 990 entries, RIP v2, IPv6 routing, Layer 3 interfaces, CIDR, PBR, DHCP server, DHCP relay, and UDP relay. For dynamic routing beyond RIP v2, choose a platform whose feature set names that protocol.
CBS350-48P-4G adds 48 10/100/1000 PoE+ ports with a 370W power budget, where CBS350-48T-4G has 48 non-PoE 10/100/1000 ports. Choose CBS350-48P-4G for powered endpoints; choose CBS350-48T-4G when separate endpoint power already exists.
CBS350-48T-4X carries 4 10 Gigabit SFP+ uplinks, where CBS350-48T-4G carries 4 Gigabit SFP uplinks. Choose CBS350-48T-4X for 10G aggregation from a 48-port copper access layer; choose CBS350-48T-4G for 1G fiber handoffs.
C1300-48T-4G is the named migration PID for CBS350-48T-4G and keeps the 48-port GE, 4x1G SFP configuration in the replacement family. Choose C1300-48T-4G for new Cisco-standardized refreshes; choose CBS350-48T-4G for like-for-like installed-base sparing.
