N Installing The Processor - AT&T MERLIN LEGEND Release 3.1 Installation Manual

Installing the Processor
Installing the Processor
Installing the processor includes the following procedures:
If both of the following conditions are true, follow the procedures in
Chapter 9, "Modifying the Processor for Key Mode."
— Form 1, System Planning, indicates Permanent Key mode.
— Form 2c, System Numbering: Line/Trunk Jacks, indicates no GS
(ground-start) trunks in the Incoming Trunk Type column.
Insert the processor into the carrier as indicated in "Installing the
Processor in the Carrier," later in this chapter.
NOTES:
1. If the system is programmed for Permanent Key mode, check the switch
setting. Refer to Chapter 9, "Modifying the Processor for Key Mode" for
detailed procedures. If the switch is set to Permanent Key-only operation,
all trunks revert to loop-start. If the switch is not set, any programmed
designation for ground-start trunks is retained.
The ground-start pool never has trunks assigned to it automatically, but
must be programmed after the ground-start ports are designated. Ground-
start trunks are assigned to the ground-start pool on initialization, except in
a system switched for Permanent Key mode operation. (In Release 1.0,
ground-start and loop-start trunks automatically defaulted to loop-start.)
2. Beginning with Release 3.0, the feature module required for Release 2.1
and earlier is no longer needed. The Release 3.0 processor module
contains a PCMCIA memory card interface capable of accommodating a
4-MB memory card. This card is used to install or upgrade system
software and perform firmware upgrades on circuit modules. It can be
used to backup and restore system programming,
