Replacing The Security Device On The Nt5D61 Iodu/C - Nortel Meridian 1 Replacement Manual

Replacing the Security Device on the NT5D61 IODU/C

Use this procedure to replace the Security Device on the NT5D61
Input/Output Disk Unit with CD-ROM (IODU/C) Card.
The Security Device is a field removable component and is located in the
upper right corner of an IODU/C card. The device does not contain feature or
software release specific information, but it has a unique custom program
necessary for each customer. It is intended to serve the customer through
numerous upgrade and feature changes.
The Security Device is replaced only if such a replacement is suggested by
maintenance and/or diagnostic programs.
Performing this procedure in a nonredundant system, such as a 51C,
will disrupt system operation. If possible, schedule the replacement at
the lowest traffic time.
See the X11 Administration (553-3001-311) for a description of all
maintenance commands, and the X11 System Messages Guide
(553-3001-411) for interpreting system messages.
Module covers are not hinged; do not let go of the cover. Lift the cover
away from the module and set it out of your work area.
At some point in this procedure the system will warm start, causing a
momentary interruption in call processing.
Note: To replace the Security Device, a new Security Device and
keycode are required. On redundant systems, the new keycode must
validate against the new and existing Security Device.
