Figure 49 Removing a subcard
Replacing a fan tray
CAUTION:
•
To avoid bodily injury, do not touch the rotating fans when replacing the fan tray.
• To ensure good ventilation, install a new fan tray within two minutes after removing the old one.
When a fan tray fails, replace the fan tray to ensure correct operation of the switch.
The fan tray removal and installation procedures for all S10500 switches are the same, even though the
fan tray slot is vertically oriented for the S10504, S10506, S10508, S10510, and S10512 switches and
horizontally oriented for the S10508-V switch. This section takes removing and installing a vertically
oriented fan tray on an S10506 as an example.
To remove a fan tray:
1. Prepare an antistatic mat to place the fan tray to be removed.
2. Put on an ESD wrist strap and make sure the wrist strap makes good skin contact and is reliably
grounded. For more information, see "
Installing FRUs ."
3. Loosen the captive screws on the fan tray.
4. Hold the handle of the fan tray with one hand to gently pull the fan tray part way out of the chassis.
After the fans stop rotating, support the bottom of the fan tray with the other hand, and take out the
fan tray from the chassis.
5. Put the removed fan tray on the antistatic mat.
6. Unpack the fan tray.
7. Holding the handle of the fan tray with one hand and supporting the bottom with the other, gently
slide the fan tray along the guide rails into the slot until it is firmly seated in the slot.
8. Fasten the captive screws on the fan tray.
