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
555-233-115
NOTE:
Because the new expansion control carrier has 6 more port slots than
the one removed, you do not need to retranslate these circuit packs.
