Install Circuit Packs
1. Replace the circuit packs and power supplies in port cabinets “C” and “D”
if they were previously removed.
2. Using the label on the front of the carrier and the annotated “list
configuration all” (provided with the Release 8r removable media), install
the control circuit packs into the new expansion control cabinet.
3. Install the port circuit packs into the “A” cabinet using the label on the front
of the carrier and the annotated “list configuration all” as a guide.
NOTE:
Since the new Release 8r expansion control carrier has 6 more port
slots than the removed control carrier, there should be no need to
retranslate these circuit packs.
4. For an EPN in a critical reliability system, install a TN2182B Tone-Clock
and a TN570 EI in slots “1” and “2” of port cabinet “B.” See
Table 3-3
.

Change Cabinet Address Plugs
If a duplicated control cabinet was removed from position “B” and was not
replaced with a new port cabinet, the upgraded EPN’s port cabinets occupy
different positions in the cabinet stack.
1. Behind each port cabinet, find the address plug attached to 2 of the 6
backplane pins to the right of the pin-field block for slot “00.”
2. Change the location of each port cabinet address plug to reflect the
cabinet’s current position. See
Figure 3-1
