The basic unit is kept cool by two fan units (two fans each), and the fans in the power supply units (three fans in each PSU) and/or the fans in the PSU dummy unit(s) (two fans in each dummy).

When a fan in a fan or power supply unit/PSU dummy module fails, the amber front identify LED (see figure 14 on page 50) on the front panel blinks. You can find out which unit is defective by checking the fan status via the server mana- gement software ServerView.

IEven though the system can continue operating with a defective fan, the defective fan or power supply unit/PSU dummy module should be replaced as soon as possible.

For how to replace a power supply unit/PSU dummy module, see section “Replacing a Power Supply Unit” on page 133.

Due to the hot-swap architecture, replacement is also possible during operation.
