Removing a fan tray
Do not touch any naked conductors or terminals on the fan tray.
Do not place the fan tray in moist place. Prevent liquid from entering the fan tray.
Do not disassemble faulty fan trays yourself. When the internal wiring or components of a fan tray are
faulty, ask maintenance engineers for maintenance.
To remove a fan tray:
1. Wear an ESD wrist strap and make sure it makes good skin contact and is reliably grounded.
2. Grasp the two handles of the fan tray, as shown by callout 1 in Figure 43, and pull out the fan tray
slowly along the guide rails.
3. Put the removed fan tray in an antistatic bag.

CAUTION:
To prevent damage to the fan tray or the connectors on the backplane, insert the fan tray gently. If you
encounter a hard resistance when inserting the fan tray, pull out the fan tray and insert it again.
Install two fan trays of the same model on the switch. Do not power on the switch when it does not have
fan trays or has only one fan tray installed.
Make sure all slots have modules or filler panels installed when the switch is operating.
To install a fan tray:
