Installing or replacing a fan module
The RackSwitch G8264CS contains up to four hot-swap fan modules. Three fan
modules are required for normal operation.
The switch continues to operate when there is one failed fan module. If one fan
fails, the switch sends an error message. If a second fan fails, the switch sends an
error message, writes a failure log to flash memory, and shuts down.
Each fan module has a green LED that is visible from the rear panel. The LED
shows the status of the fan module, as follows:
v LED is lit: Fans are operational.
v
LED is off: Switch unit has no power.
v LED flashes: Fan speed has failed. Replace the fan module.
Removing a fan module
To remove a fan module, complete the following steps:
1. Loosen the retainer screw.
2. Grasp the extractor handle and gently pull the fan module from the slot.
Attention: Replace the fan module within 5 minutes to avoid overheating the
switch.
Installing a fan module
To install a fan module, complete the following steps:
1. If necessary, remove the filler plate from the appropriate slot. Loosen the
retainer screws and slide the filler plate out of the slot.
2. Remove the fan module from the antistatic shielded bag.
3. Slide the fan module into the card guides in the open slot and gently push it all
the way into the slot, so that it firmly engages with the connector (see the
illustration). Each fan module has a mechanical guide key to prevent you from
inserting the module incorrectly.
4. Tighten the retaining screw on the fan module. Torque the screw to
approximately 4 inch-pounds (0.5 Nm).
