Connector Number A unique number used to distinguish between plug-in cards on an MSEB CRU.
Actions
Clear Loopback Test
Clears the loopback test on a plug-in card (PIC). This action clears both the internal loopback test
initiated by the Internal Loopback Test action and the external loopback initiated by the guided
procedure for troubleshooting a ServerNet fabric. The action enables ServerNet ports so that packets
can be routed to the PIC from adjacent ports on the MSEB or IOMF2 and from the PIC in another
enclosure connected by the ServerNet cable to the PIC being tested. Use this action if the $ZCMOM
process terminates while a loopback test is being performed. This action is safe to use on any PIC
even if you are not sure a loopback test needs to be cleared on the PIC.
Enable Port
Enables the port for this CRU.
Parameter: Enabled (true = enabled, false = disabled)
External Loopback Test
The external loopback test checks the circuitry of a plug-in card (PIC) to determine if ServerNet
traffic can pass through the PIC. You can use this test on a PIC installed in any port of an MSEB or
IOMF2 CRU. This test requires you to remove the ServerNet cable attached to the PIC and install a
loopback plug.
The external loopback test indicates whether or not the PIC circuitry is operational or faulty. Unlike
the internal loopback test, the external loopback test also checks the connector on the PIC.
