C1000-48P-4G-L Cisco Catalyst 1000 48-Port Gigabit 370W PoE+ Switch

48-Port Gigabit 370W PoE+ Switch

C1000-48P-4G-L is a Cisco Catalyst 1000 fixed switch with 48 x 10/100/1000 access positions with the documented PoE+ model profile and 4 x 1G SFP uplink slots. Power boundary: 370 W total PoE budget.

Exact selection decision

Calculate oversubscription and endpoint power across forty-eight access positions. Preserve a per-port power priority so critical phones, cameras or APs retain service when the aggregate request approaches 370 W.

Uplink and capacity plan

Map every uplink to optic or copper media, peer, speed, LACP group, spanning-tree role and failure behavior. Calculate access-to-uplink oversubscription from the exact port speeds; a shared four-uplink count does not make the FE, Gigabit, PoE and non-PoE models interchangeable.

Receiving and acceptance evidence

Commission representative high- and low-priority PoE endpoints, verify total draw and recovery after power interruption, then stress all four 1G uplinks under the intended VLAN and aggregation design.

Software and lifecycle record

Record serial, installed Cisco IOS release, configuration backup, management access, VLANs, security controls and supported transceivers. Cisco has announced end of sale for the Catalyst 1000 family, so verify serial-specific support and migration timing before a new deployment.
