LAN
Two MMBs are mounted to set up a redundant configuration. If one MMB fails,
processing continues.
Hot maintenance is supported for the MMB.
The MMB includes a built-in hub that has the VLAN function. The VLAN function
controls communication between partitions and communication between the REMCS
port and a partition, thereby achieving a high security level. For details, see Section
4.1.1.1, "Management LAN."
Remarks:
When Speed/Duplex for the LAN port on the MMB is set to an item other than
"AUTO," use a cross cable to connect a switching hub to the MMB LAN port.
