Campus PoE Switch for Managed Networks

The Lenovo CE0128PB is a managed L2/L3 switch built for enterprise campus deployments. It delivers 24 RJ-45 ports at 1 GbE with PoE and PoE+ support plus four SFP+ uplinks at 10 GbE. IT teams needing Layer 3 routing, VLANs, QoS and stacking in a single rack unit will find the feature set aligned with campus access-layer requirements.

Sustained Load Behaviour

Under continuous traffic the switch forwards at line rate across all 24 primary ports and four uplinks with 9216-byte jumbo frames enabled. LACP aggregates maintain throughput during prolonged transfers while QoS policies preserve priority queues. The 185 W PoE budget remains available across all powered ports without throttling, and stacking links keep control-plane consistency during extended high-utilisation periods.

Thermals Noise and Power

A single fixed 260 W AC supply (100–240 V, IEC 320-C14) powers the system and PoE loads within the 1U chassis measuring 44 mm high, 441 mm wide and 254 mm deep. Fan speed adjusts to internal temperature so acoustic output stays low in typical office rack rows. The supply headroom above the 185 W PoE ceiling ensures stable operation without external redundancy modules.

Questions about this item

How much power does the 260 W AC supply deliver to PoE devices across all 24 ports?

The switch budgets a maximum of 185 W for PoE and PoE+ across every RJ-45 port combined.

Which SFP or SFP+ transceivers must I supply myself for the four uplink ports?

The four SFP+ cages accept standard SFP or SFP+ modules; the switch ships without any transceivers installed.

Can the 10 Gbps SFP+ uplinks pass traffic to the 1 Gbps RJ-45 ports without a separate router?

Yes, full Layer 3 routing between the 10 Gbps uplinks and the 24 Gigabit ports is supported.
