6.1 Interlock Switch Disable Procedure
This procedure describes how to disable the top cover interlock switch on the front panel
using the interlock switch disable tool (P/N 29-28408-01) for troubleshooting, testing, and
adjustment purposes. Disabling this interlock switch also disables the front door lock.

Service Aid 533, as described in Section 4.5.4.4.
To disable the interlock switch, proceed as follows:
1. Switch off the tape drive and place it in the operator access position (refer to Section 5.2).
2. Insert the interlock switch disable tool into the interlock switch located behind the front
panel (see Figure 6–1) and turn the tool ninety degrees clockwise.
3. To re-enable the interlock switch, turn the tool ninety degrees counterclockwise and
remove it.
