Replacing and Cleaning

the Air Filter of Chassis

c CAUTION: You are strongly recommended to clean the air filter semimonthly to guarantee adequate ventilation.

The air filter of the Switch 8800 Family is installed at the air intake vents of the chassis. If you do not clean the air filter often, the dust accumulated on it will block the holes of the filter, hence affecting the ventilation of the chassis. For this reason, you are recommended to clean the air filter at a proper interval.

Both methods of dry-clean and rinsing are allowed. However, take care not to rub the air filter when you wash it, and simply air it after that.

Removing and cleaning the air filter of chassis

Step 1: Unscrew the captive screws at the top and bottom of the air filter with a flathead screwdriver.

Step 2: Hold the air filter at the left-rear by its upper and lower edges, pull part of it out of the chassis, put one hand underneath the air filter to hold it, and pull it out slowly along the guides.

c CAUTION: As the air filter is rather long, you should hold its front end with one hand, and bear its weight by putting another hand underneath it when sliding the air filter out of the chassis.

Step 3: Rather than taking the air filter mesh out, directly wash the air filter after removing it from the chassis, air it, and insert it into the chassis again.

Installing the air filter of the chassis

Step 1: Hold the front end of the air filter with one hand and put another hand underneath it, align it with the guides, and slide it into the chassis along the guides.

Step 2: Fix the air filter by fastening the captive screws at the top and bottom of the air filter with a flathead screwdriver.

c CAUTION: As the air filter is rather long, you should hold its front end with one hand, and bear its weight by putting another hand underneath it when sliding the air filter into the chassis.

Replacing a Module The fabric, I/O modules, and Application Modules of the Switch 8800 Family are in similar structure and can be installed and removed almost in the same way. This section describes the general procedures for removing and installing these module.

The Switch 8800 Family modules are hot-swappable.
