The MMB provides the following LAN ports for maintenance purposes.
TABLE 1.6 Maintenance LAN/REMCS LAN
Port
Description
Remarks
CE LAN
FST (CE terminal) port for use in maintenance work
100Base-TX, RJ45
REMCS LAN
For a connection with the REMCS Center (*)
100Base-TX, RJ45
*: For REMCS connection without using the management LAN
The port-based VLAN function of the switching hub on the MMB blocks communication between the CE port
and REMCS port. The following shows an outline of the maintenance LAN and REMCS LAN of the MMB.
FIGURE 1.4 Maintenance LAN and REMCS LAN of the MMB
The maintenance LAN is configured with Web-UI or CLI of the MMB. The subnet of the maintenance LAN
must be separated from the other subnets such as one for the management LAN, the production LAN, etc.
When the MMB is duplicated, the maintenance LAN can only access to the MMB on the active side. The NIC
on the standby MMB is disabled.
Remarks
The active and standby MMBs in the PRIMEQUEST 2000 series server each have a CE terminal port used in
maintenance and a LAN port for REMCS notification. Communication through the ports is enabled only on the
active MMB and disabled on the standby MMB. A field engineer configures the maintenance LAN and
REMCS LAN during system installation.
1.5 Production LAN
This section describes the configuration of the production LAN for the PRIMEQUEST 2000 series.
1.5.1 Overview of the production LAN
The IOU includes LAN ports for the production LAN.
You can mount additional LAN cards in the PCI Express slots on the IOU and PCI_Box as needed, to use
their ports for the production LAN.
