Accessing drawers
To observe or replace a DDIC, you must open the drawer in which it resides. The top drawer (Drawer 0) and the
bottom drawer (Drawer 1) are accessed from the enclosure front panel. See also Figure 25 (page 33).
Opening a drawer
1. Verify that the anti-tamper locks are not engaged. The red arrows on the locks point inward if the locks are
disengaged as shown in Figure 92. If necessary, unlock them by rotating counter-clockwise using a Torx T20
bit.
