Installing and Cabling the System
Null-Modem Cable
If you are cabling a serial device such as a laptop computer to the console connector
on the Integrated Administrator, be sure that you use the null-modem cable provided
with the enclosure and not a straight-through cable. Use Table 3-5 to determine the
specifications of this cable.

Powering Up the ProLiant BL e-Class System
As soon as you connect an AC power cord to a hot-plug power supply on the rear
panel, the enclosure powers up. Plug in the second power supply for redundancy.
As soon as you remove a server blade blank and install a server blade into the front
panel of the enclosure, the server blade powers up.
Powering Down the ProLiant BL e-Class System
You can power down one or more server blades or the entire enclosure.
