Figure 162: Removing Fan Trays
Installing an MX2008 Fan Tray
This topic describes how to install the lower fan trays in a MX2008. This procedure applies to both the
standard fan tray and the optimized power fan tray.
To install the lower fan tray (see
1. Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and connect the strap to
one of the ESD points on the chassis.
2. Reposition the DC cable manager, if necessary, before installing the lower fan tray:
Unwrap any cables on the DC cable manager and remove the cables from the tray. Arrange the cables
so that they do not block the front of the cable manager, and tray and secure them with temporary
fasteners so that they are not supporting their own weight as they hang from the connector.
3. Loosen the two captive screws on the access panel and open.
4. Remove the fan tray from the antistatic mat or ESD bag.
5. Grasp the fan tray by the handle, and place one hand under the fan tray for support. Insert the fan tray
partially into the chassis while pressing the latch.
NOTE:
When inserting the fan tray, observe the correct orientation by the "this side up"
label on the fan tray.
6. Press and hold the latch again while carefully pushing the fan tray into the chassis.
