Adding New Carriers and EPN Cabinets
Remove Circuit Packs from Port Carrier
NOTE:
Skip these steps if a switch node carrier is being added to an empty carrier
position.
1. To ensure that circuit packs and power units in the port carrier are properly
replaced, label each component with its slot number.
2. Disconnect the power cords from the power units in the carrier.
3. Remove all circuit packs and power units from carrier. Store the circuit
packs in the static-proof packaging.
4. Remove the circuit pack blanks from slots that do not contain circuit packs.

Remove Port Carrier
NOTE:
Skip these steps if standard reliability and a switch node carrier is being
added to an empty carrier position.
NOTE:
Note the position of the TDM/LAN cables before disconnecting.
1. If a switch node carrier is being installed in the D position of an EPN,
remove the TDM/LAN cable from between the D and A carriers.
For other EPNs or the PPN, disconnect 1 end of the TDM/LAN cable
(between the D and A carriers) from the D carrier.
2. Remove the ZAHF4 TDM/LAN bus terminator from slot 21 of the D carrier.
3. Disconnect 1 end of the 8 ground straps (between the D and E carriers)
from the D carrier (see
high/critical reliability, respectively). These straps will be reconnected to the
new D carrier.
4. Disconnect the 8 ground straps from the D carrier (between the D and A
carriers or the D carrier and the enhanced fan unit—see
Figure
5. Disconnect the P1 (small 9-pin) connector from the D carrier. Move the
cable into a position where it will not interfere with removing the carrier.
6. Remove the 4 screws (top 2 first) holding the D carrier to the cabinet frame.
Use a long-handle screwdriver or 5/16-inch socket with a 10-inch
extension.
