Add MCC Port Carriers
A new port carrier can be installed when additional features or equipment exceed
the capacity of the present system. Port carriers are identified as B, C, D, and E
except for a PPN cabinet with the duplication option. The “B” carrier is the second
control carrier. PEC 63155 provides the necessary equipment for adding the
carrier.
Add each new port carrier to a port network in the “B,” “C,” “D,” “E” order of carrier
positions.
Before proceeding with the addition of a port carrier, ensure that at least 3
TN1650B Memory Circuit Packs exist in the system. Refer to the section entitled
‘‘Add Memory, Replace DUPINT Circuit Pack, and Unseat Disk Drive on SPE A’’
on page 2-34
for installation instructions.
Before proceeding with the addition of a port carrier, ensure that the TN1657 Disk
Drive is of Vintage 9 (or higher). Refer to
‘‘Install V9 or Later Disk Drive(s)’’ on
for installation instructions.
