Access A Drawer; Figure 23 Safety Lock To Release Left Drawer Slide Rail (Lower Drawer Used For Relational Clarity) - Seagate Exos E 2U12 Series Hardware Installation And Maintenance Manual

Access a drawer

Each tamper-resistant drawer contains 42 slots for drives in carriers (DDICs). The drawer supports its DDIC contents and own
weight when partially or fully open. A safety latching mechanism prevents access to more than one drawer at a time.
CAUTION Only open a drawer for no more than 10 minutes, or you will compromise airflow and cooling. DDICs are hot-
swappable.
To access a drawer:
1. Confirm the drawer is in the unlocked position. If it is locked, use a T20 Torx driver to unlock each drawer pull handle by
turning both locks counterclockwise on each drawer.
2. Complete the following actions to open the upper drawer:
a. Facing the front of the 5U enclosure, press and hold both drawer pull handles while pulling outward.
b. Stop as the drawer rails engage the safety lock latches, and then access three rows of slots for drive modules in their
carriers (DDICs).
3. Complete the following actions to close the upper drawer:
a. Press and hold the safety lock latches with the blue touchpoint at the front of both extended drawer slide rails.

b. Pressing simultaneously inward, begin sliding the upper drawer back into place until the safety lock clears the opening.
c. Placing the heels of both palms against the face of the drawer near the anti-tamper locks, exert even inward pressure
until the drawer is almost flush with the rack ear flanges.
d. Simultaneously press inward and hold both drawer pull handles as you push the drawer closed until it fully latches.
4. (Optional) Use a T20 Torx driver to lock each drawer pull handle by fully turning both locks clockwise on each drawer, and
then confirm the locks properly latched by attempting to open the drawer.
