System 75 XE to R8si (Blowback)

Remove circuit packs from the carrier [75 XE upgrade]

Return to Task List


Danger! 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.

  1. Label each port circuit pack in control cabinet A with its slot number.

  2. Remove all circuit packs and power units from the control cabinet. Store the circuit packs in the static-proof packaging.


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).

  1. If a TN741 (or an international TN419A) Tone-Clock resides in port cabinet B, remove this circuit pack from the port cabinet. It will not be reused.
