Install circuit packs into the port cabinets [75 XE upgrade]
Return to Task List
!
Before inserting or removing a circuit pack from a cabinet, put on a wrist strap and attach
its plug or clip to the cabinet's frame.
!
The replaced port circuit packs must conform to the usable vintage requirements for a
Release 8si system (see Reference Guide for Circuit-Pack Vintages and Change Notices).
1
Using the label and the annotated
translation memory card), install the Release 8si control circuit packs into the new enhanced
control cabinet(s) or the expansion control cabinet, as appropriate.
NOTE:
You can use a TN756 Tone Detector/Generator in an upgraded PPN system. You can not
use the TN756 in an EPN upgrade. If a TN756 is being replaced by a new tone-clock
during the upgrade, you will replace this circuit pack either with a TN2182 tone-
clock/tone detector or with both a new Release 8si tone-clock (TN768 or TN780) and a
new tone detector (TN748B).
2
Reinstall the previously-removed port circuit packs into the A cabinet using the decal and the
annotated
as a guide.
NOTE:
If a TN2182 is installed, do not reintstall the TN756 in the port network.
You do not need to move and retranslate these circuit packs. The new Release 8si enhanced
control cabinet has 2 or 3 more port slots than the System 75 control cabinet you removed.

Change cabinet address plugs [75 XE upgrade]
Return to Task List
If a duplicated control cabinet was added to position B and did not replace a port cabinet, the upgraded
PPN's port cabinets occupy different positions in the cabinet stack. You must change the location of each
port cabinet's address plug to reflect the cabinet's current position (see
location,
on page 248).
The cabinet address plug-pins are to the right of the pin-field block for slot 00. For each port cabinet,
attach the address plug to the pair of backplane pins corresponding to the cabinet's position in the stack.
