Option 11C DTI operation is monitored and reported on through maintenance
messages, out-of-service alarms, and circuit card faceplate LEDs.
Option 11C maintenance provides several tools, either manual or automatic,
for maintaining effective DTI operation. These tools are service change and
maintenance commands that are accessible through the software overlays and
resident diagnostic routines.
To replace a DTI circuit pack, follow the procedure below:
1 Software disable the NTAK10 2.0 Mb DTI card(s) using LD 60
(command DISL N, where N is the 2.0 Mb DTI card number).
2 Software disable the clock controller using LD 60 (DIS CC 0).
3 Hold the NTAK10 by the lock latches, unlock the latches and slide the
card out of the cabinet. Once out of the slot you may remove any of the
daughterboards.
To avoid damage to the circuit cards from electrostatic discharge, wear
the wrist strap connected to the inside of your Option 11C cabinet
whenever handling the circuit cards. Figure 7 shows the location of the
wrist strap in relation to the cabinet.
