8.3 Air Filters
Both the Netra CT 810 servers and the Netra CT 410 servers have two types of air
filters: a power supply unit air filter, which filters the air going into the power
supply, and a main air filter, which filters the air going into the server. Both air filters
are located in the power supply unit. The power supply unit air filter is located at
the front of the power supply unit, and the main air filter is located in a tray at the
top of the power supply unit.
Both sets of air filters should be replaced every three to six months. If your server
environment is especially dirty, you might need to replace them more frequently.
The power supply unit air filter must be in place for safe operation. Note that you do
not have to power off the power supply unit or the system when removing or
installing any of the air filters.
There is a single part number for the kit that contains both the main air filter and the
power supply unit air filter for the Netra CT servers.
8.3.1 Removing the Air Filters
1. Squeeze in on the tabs at the sides of the power supply unit cover, and remove the
cover.
