Installing the System into a Rack
007-5536-001 17
Note that all power and data cables should be routed in such a way that they do not block the
airflow generated by the fans.
Providing Power
Plug the power cord from the server power supply unit into a rack power distibution unit (PDU)
or high-quality power strip that offers protection from electrical noise and power surges.
For higher availability it is recommended that you use an optional uninterruptible power supply
(UPS) with the server.
Finally, press the power-on button on the front-left node of the chassis and then the power button
on the front-right node, see Figure 2-4 on page 17 for an example.
Note: The Overheat/Fan fail LED is a bi-color (Red/Blue) that can indicate unit identification
(UID) when activated by an IPMI tool command, or manually by a switch on the chassis rear.
