Replacing FRUs
CAUTION:
•
When you hot-swap an FRU, ensure electrical safety.
• To avoid device damage and bodily injury, follow the replacing procedures strictly.
The switch adopts the modular architecture and supports hot swapping of FRUs.
Replacing a fan tray
Follow these guidelines when you replace a fan tray:
• Never touch any part of the fans.
• Take out the fan tray after the fans completely stop rotating.
• The switch supports 1+1 fan tray redundancy. When one fan tray fails, the device can operate
correctly if the failed fan tray is still in position. You do not need to replace the failed fan tray
immediately.
Replacing the LSVM1S9800FAN/LSVM2S9800FAN fan tray
CAUTION:
•
When an LSVM1S9800FAN/LSVM2S9800FAN fan tray fails,
{
Do not remove the fan tray if you cannot replace the fan tray immediately.
{
Finish replacing the fan tray within 5 minutes.
• When both fan trays fail, replace the fan trays one after another. Make sure the device does not operate
for more than 3 minutes when no fan trays are installed.
The replacing procedures are the same for the LSVM1S9800FAN and LSVM2S9800FAN fan trays.
To replace the LSVM1S9800FAN/LSVM2S9800FAN fan tray:
1. Wear an ESD wrist strap and make sure it makes good skin contact and is reliably grounded.
2. Loosen the captive screws on the fan tray with a Phillips screwdriver until they are completely
disengaged from the switch chassis.
3. Grasp the handle of the fan tray with one hand and pull the fan tray part way out the slot. Support
the fan tray bottom with the other hand, and pull the fan tray slowly along the guide rails out of the
slot.
4. Put the removed fan tray into an antistatic bag.
5. Install a new fan tray. For more information, see " Installing the
LSVM1S9800FAN/LSVM2S9800FAN fan tray for the S9804 switch ."
