Initially Powering On the System
If you are powering on the system for the first time, or if the system is completely shut
down, use these procedures to power on the server.
The multimodule System Controller (MMSC) display can be used to power on and
power off the entire rack configuration after initial power on (see Chapter 7, “Using the
System Controller”).
1. Verify that the system power switch, located in the lower rear of the system chassis,
is turned off.
2. Insert the PDU system power cable into the 200-240 VAC wall receptacle (see
Figure 5-6).
Warning:
The SGI 2400 and 2800 rackmount systems operate on 200-240 VAC.
Use extreme caution when working around this voltage. Never install or remove
power cords without first turning off the equipment.
3. Connect the power cord(s) of the system module(s) into either of the top two
(20-amp) receptacles of the PDU (see Figure 5-6).
Caution: The system modules must be plugged into the PDU that is supplied with
the rack. Do not use a power source outside of the chassis. The CrayLink Interconnect
cabling scheme requires that the system modules share a common AC ground. This
helps prevent damage to internal hardware components.
4. Connect the MMSC power cord to the PDU.
5. If the monitors and peripherals are equipped with voltage select switches, verify
that they are set for the appropriate AC voltage.
6. Connect the power cords from the monitor(s) and additional peripherals to the
appropriate three-pronged grounded outlets.
7. Turn on the system power switch (see Figure 5-7).
8. Turn on the system modules (see Figure 5-8).
9. Turn on the monitors, followed by any attached peripherals.
Note:
All internal storage devices are automatically powered on by the System
Controller.
10. Boot the system as described in “Booting Your System” on page 73.
