Removing Covers - Rack Mount LH 3000r
WARNING Before removing covers, disconnect the power cords and unplug telephone cables.
If possible, shut down the operating system. Disconnect the power cords to avoid
exposure to high energy levels that may cause burns when parts are short-circuited
by metal objects, such as tools or jewelry. Disconnect telephone cables to avoid
exposure to shock hazard from telephone ringing voltages.
Wear a grounded wrist strap and use a static-dissipating work surface when
handling NetServer components. Note that the power switch does not turn off the
standby power. Disconnect the power cord to turn off standby power.
NOTE If the backlight of the LCD is on, standby power is also on.
1. Extend the anti-tip foot from under the front of the rack.
WARNING This anti-tip device must be extended to prevent the rack and NetServer from tipping
over, which could damage the NetServer and injure people.
