When using the SGI cluster manager software, you can monitor and manage your server from a

Preparing to Power On
To prepare to power on your system, follow these steps:
1. Check to ensure that the cabling between the rack’s power distribution units (PDUs) and the
wall power-plug receptacle is secure.
2. Setting the circuit breakers on the PDUs to the “On” position will apply power to the blade
enclosure supplies and will start the chassis manager board in each enclosure.
Tip: The chassis manager in each blade enclosure will stay powered on as long as there is
power coming into the unit. Turn off the PDU breaker switch that supplies voltage to the
enclosure if you want to remove all power from the enclosure.
3. If you plan to power on a server that includes optional mass storage enclosures, make sure
that the power switch on the rear of each PSU/cooling module (one or two per enclosure) is
in the
1
(on) position.
4. Make sure that all PDU circuit breaker switches (see the examples of I/O-rack PDUs in
Figure 1-3 on page 6, and Figure 1-4 on page 7) are turned on to provide power when the
system is booted up.
