10 Embedded NICs/LAN on Motherboard (LOM)
The Dell™ PowerEdge™ T310 has an embedded dual-port Gigabit Ethernet. The embedded Broadcom
®
5716 LAN controller is on the T310 planar as an independent Gigabit Ethernet interface device. There
is one RJ-45 connector on the back of the system. The firmware for the LOM chip resides in a flash
part.
