The SAN48B-5 has two power supply and fan assemblies, as shown in Figure 14.
Fabric OS identifies the assemblies from right to left on the non-port side as
assembly 1 and assembly 2. (The actual appearance of the switch may differ from
this illustration but the locations are correct.)

Attention: Disassembling any part of the power supply voids the part warranty
and regulatory certifications. There are no user-serviceable parts inside the power
supply and fan assembly. The cooling system relies on pressurized air, do not leave
either of the power supply and fan assembly slots empty longer than two minutes
when the switch is operating. If a power supply and fan assembly fails, leave the
power supply and fan assembly in the switch until it can be replaced. Maintain
both power supply and fan assembly in operational condition to provide
redundancy.
Table 7 describes the power supply and fan assembly status LED colors, behaviors,
and actions required, if any.
