Detecting problems in the VM600 MPS rack
MAINTENANCE AND TROUBLESHOOTING
14.5.2.2 CPUM card
The CPUM cannot be hot swapped, that is, it is necessary to switch off (or disconnect) the
rack power before replacing this type of card.
NOTE: The removal of a CPUM card requires both strength and care!
Note that this card does not employ the lever mechanism described in
14.5.2.1 General precautions for removing cards.
The replacement CPUM card must have exactly the same hardware configuration (jumper
settings) as the original (suspect) CPUM card.
The replacement CPUM card must also have the same sub-modules installed as the original
card. This will allow the same communications possibilities.
Once the replacement CPUM card has been installed, the entire MPS (VM600 rack)
configuration must be downloaded using the VM600 MPSx software.
14.5.2.3 IOCN card
The IOCN can be hot swapped, therefore it is not necessary to switch off (or disconnect) the
rack power before replacing this type of card.
The replacement IOCN card must have exactly the same hardware configuration (jumper
settings) as the original (suspect) IOCN card.
14.5.2.4 RPS6U rack power supply
In a VM600 rack containing only one RPS6U rack power supply (that is, a configuration
without rack power supply redundancy), it is obviously necessary to interrupt the rack power
while the rack power supply is being replaced. The power should be switched off (or
disconnected) before the suspect rack power supply is removed and only switched on (or
reconnected) once the new rack power supply is installed.
In a VM600 rack employing two RPS6U rack power supplies to support rack power supply
redundancy, the rack and cards can continue to be powered while one of the rack power
supplies is being replaced (see 2.10.5 Racks with two RPS6U rack power supplies in order
to support rack power supply redundancy).
