When the NI port of a laptop without AC power (that is, operating only on battery mode) is connected to the PoE module (WS-X4748-RJ45V+E), the NIC link does not come up (i.e., remains in disconnected status).

Neither issuing shut then no shut nor disabling then re-enabling the NIC port resolves the problem.

- PoE module(WS-X4748-RJ45V+E)
- Laptop NIC vendor: Marvell
- AC Power is not connected
