Field-replaceable units (FRUs)
The switch has two power supply (Figure 4 on page 5) and three fan assembly
(Figure 5 on page 5) FRUs that are redundant and hot swappable. The FRUs are
capable of functioning universally (100 - 240 VAC input range) without voltage
jumpers or switches. The power supply FRUs are identical and interchangeable;
the fan assembly FRUs are also identical and interchangeable. The switch chassis
itself (Figure 6 on page 6) is also a FRU.
Smart cards, which provide additional encryption security management options,
are available through IBM as FRUs. See the Fabric OS Encryption Administrator's
Guide Supporting Tivoli Key Lifecycle Manager (TKLM) Environments for more
information regarding this recommended optional functionality. Part numbers for
FRUs are listed in "Parts list (FRUs)" on page 52.
