You can install or remove a hot-swap component while the EXP2500 is running. For
information about installing hot-swap components, see Chapter 4, "Parts listing,
EXP2512 and EXP2524 expansion enclosures," on page 25.
Blue on components and labels indicates touch points, where you can grip a
component, move a latch, and so on.

The major CRUs in the EXP2500 are SAS, nearline SAS, or Solid State hard
disk drives, ESMs, and power supplies. See "Replaceable EXP2500
components" on page 25.
All CRUs have fault or status light emitting diodes (LEDs) to indicate hardware
failures.
The EXP2500 uses a dual ac input power system. The redundant cooling of the
fans enables continued operation if up to three fans fail. The EXP2500 comes
with two 800-watt hot-swap power supplies, which provide redundant power for
all EXP2500 configurations. If a problem occurs with one of the power supplies,
the other power supply can meet the power requirements.
