Excluding a Hardware Element and Checking Exclusion Status
As Customer Administrator, you can logically Exclude a redundant hardware element from
the domain until it has been repaired or replaced. Exclusion is taken into account at the next
domain power ON. Hardware exclusion status can be viewed from the Domain Hardware
Details page. See Excluding / Including Hardware Elements, on page 4-17.
Checking, Testing and Resetting the PMB
The PMB is located in the module at the base of the cabinet and links the server to the PAP
unit via an Ethernet link. You may be required to carry out the following checks / actions:
• Check that PMB LED #0 is blinking green (PMB booted correctly):
When the system is powered on, the 7 activity and status LEDs (LED #1–LED #7) are
switched off and LED #0 is blinking.
• Check that PMB code wheels are set as follows:
CSS Cabinet Hexadecimal Code
(0 to F)
CSS Module Hexadecimal Code
(0 to F)
0 0
• Check that the Ethernet cable linking the server to the PAP unit is correctly inserted and
that the Ethernet link LED is green.
• Check the PAP – PMB link by pinging the PAP and the PMB:
PAP Address
