DANGER
:
DANGER: The latch on the power supply acts as the DC power switch and removes only DC
power from the backplane. To remove the AC power from the cabinet, pull the AC
power cord from the back of the cabinet.
2. Unplug the power cord from the back of the cabinet to turn off the cabinet.
Replacing the processor circuit pack
To replace the processor circuit pack:
1. Remove the entire processor circuit pack.
2. Place the circuit pack in an antistatic carrier or bag. You might need to reinstall this circuit
pack if you must stop the migration.
3. Remove the TN2182 Tone Clock circuit pack.
4. Remove the octopus cable from the connector that is associated with slot 2 on the
connector panel.
5. Install the IPSI adapter to the connector that is associated with slot 2 on the connector

6. Install the maintenance cable onto the 9-pin D-sub connector on the adapter. This cable is
for emergency transfer and "auxsig" signal.
Note:
Note: The TN2312BP Internet Protocol Server Interface (IPSI) circuit pack takes only
one slot.
7. Insert the TN2312BP Internet Protocol Server Interface (IPSI) circuit pack into slot 2.
8. Attach the new label above the circuit pack slots.
