Replacing the LSVM1S9810FAN/LSVM2S9810FAN fan tray
CAUTION:
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.
The replacing procedures are the same for the LSVM1S9810FAN and LSVM2S9810FAN fan trays.
To replace the LSVM1S9810FAN/LSVM2S9810FAN 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
LSVM1S9810FAN/LSVM2S9810FAN fan tray for the S9810 switch ."
Replacing a switching fabric module
IMPORTANT:
Remove the fan tray in fan tray slot 1 before you remove the switching fabric module in slot 10. Remove
the fan tray in fan tray slot 2 before you remove the switching fabric module in slot 11. For more
information about replacing fan trays, see "Installing the LSVM1S9810FAN/LSVM2S9810FAN fan tray
for the S9810 switch."
CAUTION:
To avoid LPU damage, do not make the S9810 switch operate for more than 5 minutes when the switch
has no switching fabric modules installed.
To replace a switching fabric module:
1. Wear an ESD wrist strap and make sure it makes good skin contact and is reliably grounded.
2. Use a screwdriver to loosen the captive screws from the switching fabric module. Pull the ejector
levers at both sides of the switching fabric module outward and pull the switching fabric module
along the guide rails part way out. See Figure 40 .
3. Supporting the module bottom, pull the module completely out of the switch chassis. See Figure
41 .
4. Install a new switching fabric module. For more information, see " Installing switching fabric
modules for the S9810 switch ."
