Installing and removing a fan tray
CAUTION:
•
For adequate heat dissipation, you must install five fan trays of the same model for the switch.
•
Make sure all slots have a module installed when the switch is operating.
•
If more than one fan tray fails during switch operation, do not remove the failed fan trays
simultaneously. Replace the fan trays one by one and finish replacing each fan tray within three
minutes.
Installing a fan tray
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 while inserting the fan tray, pull out the fan tray and insert it again.
Select fan trays for the switch as needed. For the fan trays available for the switch and their
specifications, see "
To install an LSPM1FANSA or LSPM1FANSB fan tray:
1.
Wear an ESD wrist strap and make sure it makes good skin contact and is reliably grounded.
2.
Unpack the fan tray and verify that the fan tray model is correct.
3.
Orient the fan tray with the "TOP" mark facing upward. Grasp the handle of the fan tray with one
hand and support the fan tray bottom with the other, and slide the fan tray along the guide rails
into the slot until the fan tray is fully seated in the slot and has a firm contact with the backplane.
