Lenovo CE0152PB Gigabit Ethernet Campus Switch with Power over Ethernet

7Z350022WW (machine type and model 7Z35CTO2WW, feature code B59R) is the Lenovo CE0152PB Switch, a 1U access-layer switch with 48 fixed 10/100/1000 Mb RJ-45 ports that supply Power over Ethernet, plus four SFP/SFP+ ports that take 1 GbE or 10 GbE optical transceivers, 10 GbE active optical cables or 10 GbE direct-attach copper cables. The same CE0152PB hardware carries the number 7Z370022WW (7Z37CTO2WW, feature code B59V) under a different machine type.

Each RJ-45 port can deliver up to 15.4 W of 802.3af PoE or up to 30 W of 802.3at PoE+, and the switch supports up to 24 ports of 15.4 W or 12 ports of 30 W at the same time. Total PoE output across all ports is 370 W, drawn from one fixed 460 W AC power supply with an IEC 320-C14 inlet. The SFP+ ports carry no PoE.

The switch is non-blocking with wire-speed forwarding: up to 176 Gbps of switching throughput, up to 130 million packets per second with 64-byte packets, a 1.5 MB buffer and jumbo frames up to 9216 bytes. It holds 16384 MAC addresses and 4093 VLANs, and it runs Lenovo Campus Networking OS with Layer 2 and Layer 3 switching, static routing, RIP and OSPF.

Up to eight CE0128TB, CE0128PB, CE0152TB and CE0152PB switches can be stacked and managed as one unit. Management is through an out-of-band 10/100 RJ-45 port, an RS-232 console port, a web interface, the command line and SNMP v1, v2 and v3. Three fixed internal fans move air side to side. The chassis is 44 mm high, 441 mm wide and 254 mm deep and weighs 4.6 kg.

The package holds a pair of 2-post rack mount brackets, a 2 m RJ-45 to DB-9 console cable and a documentation flyer. A power cable and any SFP/SFP+ transceivers or cables are separate parts.
