To insert a module:
1. On the replacement module, press the release latch to release the handle.
2. Insert the module into disk bay. Note the orientation of module.
3. Continue to slide the module down until it contacts the baseboard and begins to engage
the handle. Carefully press down on the handle until it latches which will cam the disk
module into place.
4. Close the enclosure cover.
5. Swing down both handles completely to engage the locks.
NOTE : Both cover locks must be engaged before pushing the enclosure into the
rack. Otherwise, open cover alarm will sound.
6. Depress the rail locks on both sides and push the enclosure back into rack.
3.2.4 Replacing a 5V Regulator
NOTE : When a 5V regulator 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 module is
inserted and powers up.
To replace a 5V regulator:
1. Identify the failed 5V regulator with an amber Fault LED.
2. Pull and swing open both handles. This will release the cam assembly and the module
will begin to slide out of the bay.
3. Continue pulling the module completely out of the enclosure.
4. Slide in the replacement module and engage the locking handles to cam the module
into place. Ensure that both handles are completely closed.
After a few moments, the SS8460 will detect the replacement module. At this time, the
cooling fans will return to normal operation.
