Hot-plug components
This section describes how to handle hot-plug components and how to modify
your server hardware (e.g. adding/replacing hot-plug power supply units or hot-
plug HDD modules).
The hot-plug procedure increases the availability of system operation and
guarantees a high degree of data integrity and failsafe performance.
8.1.1
Hot-plug power supply units
I
A redundant power supply can be created by installing a second hot-
pluggable power supply unit (optional). If one power supply unit fails, the
other unit ensures operation can continue. The defective power supply
unit can be replaced without interrupting operation.
8.1.1.1
Removing dummy module
The slot for the second hot-plug power supply unit contains a dummy module.
This dummy module must be removed before installing a second power supply
unit.
Ê
Remove the dummy module from the second power supply unit slot.
V
CAUTION!
Keep the dummy module for future use. If the power supply unit is
removed and not replaced with a new unit, the dummy module must be
reinstalled due to cooling, to comply with applicable EMC regulations
(regulations on electromagnetic compatibility) and to protect against fire.
8.1.1.2
Adding a hot-plug power supply unit
Ê
Slide the second power supply unit into the empty slot until it locks into place
(see
section "Replacing the hot-plug power supply unit"
) and connect it up
(see
"Connecting the server to the mains" on page 55
).
