3.2.2 Replacing an I/O Module
NOTE : When an I/O module is removed, the fans (in the PCMs) will increase to
maximum speed. This is to maintain proper cooling inside the enclosure.
Fans will return to normal operation when the replacement I/O module is
inserted and powers up.
To replace an I/O module:
1. Identify the failed I/O module with an amber Fault LED.
2. Label the cables as they will need to be connected to the same ports on the replacement
module. This is particularly important if your SS8460 is in a zoned configuration.
3. Disconnect the I/O cables from the module to be replaced.
4. Pull and swing open both handles. This will release the cam assembly and the I/O
module will begin to slide out of the bay.
5. Continue pulling the module completely out of the enclosure.
6. Slide in the replacement module and engage the locking handles to cam the module
into place. Ensure that both handles are completely closed.
7. Reconnect the I/O cables to their original port connectors.
After a few moments, the SS8460 will detect the replacement module. At this time, the
cooling fans will return to normal operation.
