System 310
Parts of the Chassis
If your system will be using AC current rated differently from the
setting indicated on the label, you can easily change these default
settings. Chapter 5 in this manual contains directions for changing
the voltage selector and the fuse. Whenever you change the voltage
setting, be sure to also replace the power cord with one designed for
the fixtures in your area.
The only parts of the AC power panel you should ever have to change
are the fuse, voltage selector board, and power cable. If the AC line
filter needs service, refer to the System 310 Hardware Maintenance
Manual for repair and replacement instructions.
HE INSIDE OF HE CHASSIS
This section describes the location and function of three pieces of
hardware that are found inside every System 310 chassis. You reach
these parts by removing the back panel or cover. The parts covered
in this section are listed below:
Fans
Power supply
Cardcage and backplane
WARNING
Because of the risk of electrical shock or fire,
only qualified service technicians should
attempt to remove the cover of the chassis.
The parts inside the chassis are shown in Figure 2-2. While operators
can safely change boards in the cardcage when the system is unplugged,
the rest of the parts shown in this figure should be changed only by a
qualified service technician. The figure is included so you do not have
to open the chassis to see inside.
Refer to Chapter 5 in this manual for instructions on how to install or
remove boards in the cardcage and jumpers on the backplane. For
repair and replacement information, refer to the System 310 Hardware
Maintenance Manual.
FANS
The System 310 contains two fans mounted on the inside of the
chassis. One cools the power supply and peripherals; the other cools
the cards in the cardcage. To keep your system from overheating,
always operate it with the top cover on and all connector and
peripheral installation holes plugged. Only the vents in the chassis
cover should remain open.
