Replacing a fan tray
CAUTION:
•
When you replace a fan tray from a running device, be cautious
of electricity hazards, and do not touch the rotating fans to avoid
bodily injury.
•
When two fan trays are installed, follow these guidelines to
replace the fan trays:
{
If one fan tray fails, the switch can operate correctly if you
keep the failed fan tray in position, and immediate
replacement is not required. If you want to replace the
failed fan tray, finish the replacement within 3 minutes.
{
If both fan trays fail, replace the fan trays one after
another. Make sure the device does not operate for more
than 2 minutes when no fan trays are installed.
•
Make sure the new fan tray is the same model as the replaced
one.
To replace a fan tray:
1.
Prepare an antistatic bag for the removed fan tray.
2.

contact and is correctly grounded.

chassis. See callout 2 in
