Powering the system up and down

This section explains how to power up and power down individual units, or your entire Integrity MC990 X
system, as follows:
• Preparing to power up on page 16
• Powering up and down from the command line interface on page 17
• Booting directly from an RMC on page 17
Using an RMC connection, you can power up and power down an individual MC990 X server chassis, or
the entire system.

Preparing to power up

About this task
To prepare to power up your system, follow these steps:
Procedure
1. Check to ensure that the power connector on the cable between the rack PDUs and the wall power-
plug receptacles are securely plugged in.
2. For each individual MC990 X server chassis that you want to power up, make sure that the power
cables are plugged into all the chassis power supplies correctly, see the example in Figure 8: MC990
X server chassis power supply cable location on page 16. Setting the circuit breakers on the
PDUs to the (On) position will apply power to the individual MC990 X server chassis and will start the
RMC if it is plugged into the same PDU. Turn (Off) the PDU breaker switch on the PDU(s) that supply
power to the MC990 X server chassis or RMC power supplies if you want to remove all power from a
particular unit.
