10. (IBM Business Partners only) Restart the server. Confirm that it starts correctly
and recognizes the newly installed devices, and make sure that no error LEDs
are lit.
11. (IBM Business Partners only) Complete the additional steps in “Instructions for
IBM Business Partners” on page 31.
If you have other devices to install or remove, do so now. Otherwise, go to
“Completing the installation” on page 135.
Installing a hot-swap dc power supply
The following notes describe the type of power supply that the server supports and
other information that you must consider when you install a power supply:
v
Before you install an additional power supply or replace a power supply with one
of a different wattage, you may use the IBM Power Configurator utility to
determine current system power consumption. For more information and to
download the utility, go to http://www-03.ibm.com/systems/bladecenter/resources/
powerconfig.html.
v
The server comes with one hot-swap 12-volt output power supply that connects
to power supply bay 1. The input voltage is -48 V dc or -60 V dc auto-sensing.
v Before you install a dc power supply in the server, you must remove all ac power
supplies. Do not use both ac and dc power supplies in the same server. Install
up to two dc power supplies or up to two ac power supplies, but not a
combination.
v
Power supply 1 is the default/primary power supply. If power supply 1 fails, you
must replace the power supply with the same wattage immediately.
v You can order an optional power supply for redundancy.
v
These power supplies are designed for parallel operation. In the event of a
power-supply failure, the redundant power supply continues to power the system.
The server supports a maximum of two power supplies.
v
It is the customer's responsibility to supply the necessary power cable.
To reduce the risk of electric shock or energy hazards:
– Use a circuit breaker that is rated at 25 amps.
– Use 2.5 mm
2
(12 AWG) at 90° C copper wire.
– Torque the wiring-terminal screws to 0.50 ~ 0.60 newton-meters (4.43 ~
5.31 inch-pounds).
For more information, see Statement 34 on page 121.
v If the power source requires ring terminals, you must use a crimping tool to
install the ring terminals to the power cord wires. The ring terminals must be UL
approved and must accommodate the wire that is described in the
above-mentioned note .
Statement 29:
CAUTION: This equipment is designed to permit the connection of the earthed
conductor of the dc supply circuit to the earthing conductor at the equipment.
