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 
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 
Table 3-3.
