2. Route the power cables through the plastic strain-relief ties.
3. Route all cables along the rack cabinet rails.
Important: Allow slack in all cables to avoid tension in the cables and to allow
you to remove adjacent modules from the BladeCenter S chassis without
having to remove the cables.
4. Use the cable ties and cable straps to secure the cables together and attach
them to the rack cabinet rails.
Connecting the BladeCenter S chassis to power
Power is supplied to the BladeCenter S chassis when you connect one end of each
power cord to a power connector on the rear of the BladeCenter S chassis and the
other end of each power cord to a power distribution unit (PDU) or appropriate
electrical outlet. The BladeCenter S chassis does not have a power switch.
After you connect and route the cables, supply power to the BladeCenter S chassis
and verify that it is working correctly:
1. Connect each power cord from the power supplies to a 110 V ac or 220 V ac
PDU or electrical outlet.
2. Verify that the following LEDs are lit:
v The power-on LED on the system LED panel.
v The dc power and ac power LEDs on each power module.
v The OK LED on the advanced management module.
v The OK or Power LED on each I/O module.
Note: Initially, the port fault LEDs on the SAS connectivity module might be
flashing amber because the external ports are disabled by default. The ports
will be enabled when you complete the initial configuration of the advanced
management module.
v The power-on LED on each blade server. You might have to turn on each
blade server separately.
Disconnecting power from the BladeCenter unit
Disconnect power from the BladeCenter S chassis by shutting down all blade
servers and disconnecting the BladeCenter S chassis from all power sources.
Procedure
1. Shut down each blade server. See the documentation that comes with your
blade server for information about shutting down the operating system on the
blade server.
2. Disconnect all power cords on the BladeCenter unit from the power connectors.
Note: After you disconnect the BladeCenter S chassis from power, wait at least
5 seconds before you connect the BladeCenter S chassis to power again.
