2.3 THE 7C04 CHASSIS POWER SUPPLY MODULE
The 7C04 Chassis is equipped with a removable power supply
module. The power supply module which is located in the right
section of the chassis (Figure 2-2) operates on either 120 volts or
240 volts (AC) and automatically senses input power. The modular
nature of the chassis’ power supply allows it to be easily removed
and/or replaced.
2.3.1 Unpacking the Power Supply Module
Unpack the power supply module by using the following steps:
1. Remove the power supply module from the shipping box.
(Save the shipping box and packing materials in the event the
power supply module must be reshipped.)
2. Slide the two foam end caps off the unit and remove the plastic
bag.
3. Examine the power supply module and check for damage. If
damage exists, DO NOT install the power supply module;
contact Cabletron Systems Technical Support. Otherwise,
install the power supply module (see Section 2.3.2).
2.3.2 Installing the Power Supply Module
To install a power supply module in the 7C04 Chassis, use the
following steps and refer to Figure 2-3.
1. Hold the power supply module by placing one hand on the
handle located on the front panel and using the other hand to
support the body of the module.
2. Make sure you hold the power supply module in the upright
position. A recessed notch running from the front panel to the
back of the module is present only on the top of the module.
