Fan Subassemblies

This chapter contains procedures for removing and replacing the two fan
subassemblies of the Netra T4 system unit, as shown in

FIGURE 7-1

The chapter contains the following sections:

■

Section 7.1, “PSU Fans” on page 7-2

■

Section 7.2, “CPU Fan Assembly” on page 7-5

Caution –

The plug at the end of the AC power cord is the primary means of

disconnection for the Netra T4 AC 100 system.

Caution –

To isolate the Netra T4 DC100 system, open the circuit breakers in both

negative supply conductors.
