WARNING
Power supplies contain dangerous
voltages. Before attempting to work on any
power supply always unplug the device and
drain the power source by turning the
server on after the power supply has been
disconnected. Failure to follow these
instructions could result in serious injury
due to electrical shock.
To satisfy reliability requirements, TAG servers
are designed with Hot-Swappable power
supplies. If in the event of a power supply
module failure or if the power source fails and
only one module is receiving power, an audible
alarm sounds. For procedures on how to Hot-
Swap a power supply module refer to the
Procedures Section of this manual. Replacing
a Hot-Swap power supply.
Although most TAG power supplies for the 1U
and 4U series servers are similar in physical
sizes, and physical characteristics, some
servers use smaller foot print power supplies.
Figure 4-11 shows a typical 4U Hot-Swap
power supply.
