Replacing a fabric module
CAUTION:
•
Remove the fan tray before you remove a fabric module. Reinstall the fan tray immediately after
you finish installing or replacing a fabric module on an operating device. After the fan tray starts
operating, you can replace or install fabric modules whose slots are covered by the other fan tray.
•
The smart speed adjustment feature increases the fan speed when only one fan tray is operating.
Take noise protection measures such as wearing an earmuff or earplug. In addition, make good
preparation before hot swapping a fabric module to minimize the operation time.
To replace a fabric module:
1.
Prepare an antistatic mat to place the removed fabric module.
2.
Wear an ESD wrist strap, and make sure it makes good skin contact and is reliably grounded.
For more information, see "Installing FRUs."
3.
Press the buttons on the ejector levers to release the ejector levers. Simultaneously rotate
outward the ejector levers and pull the fabric module part way out of the slot.
4.
Holding the fabric module bottom with the right hand and the middle part with the left hand, pull
the fabric module slowly out of the slot along the guide rails.
5.
Place the removed fabric module on the antistatic mat.
6.
Install a new fabric module. For the fabric module installation procedure, see "Installing FRUs."
