to the Base network ports of the switch modules in slots 2X and 3X. The LOM supports Wake
on LAN (WOL) and PXE functions.

Connections between the LOM and I/O modules
NOTE
l
In addition to the LOM, the compute node connects to the Fabric ports of the switch modules
through the network ports on mezzanine cards.
l
Powering off the compute node forcibly will make the WOL function of the LOM ports invalid.
l
If flow control is enabled for a LOM port, the switch module connected to the LOM port must also
have flow control enabled.
