Turn off the system power and unplug the
power cord and all peripherals before
opening the system or connecting or
removing any peripheral device. Always turn
on any external peripheral device before you
turn on the system.
To avoid damaging the system, do not open
the housing for service or upgrades, unless
you are a qualified technician.
When you power off the system, the RDM
module still receives direct current so that it
can check the system's status. Be sure to
unplug the power cord before you install or
remove the RDM module.
