CHAPTER 5
IN TALLING AND REMOVING PART
This chapter describes how to remove and install many of the
components in the System 310 chassis. The intent is to show you how
to reconfigure, not service, your system. Service information is
contained in the System 310 Hardware Maintenance Manual.
This chapter provides step-by-step instructions for installing and
removing the following parts:
• Fuse and voltage selector
• Back panel, connectors, and jumpers
• Top cover
• Backplane and cardcage priority and interrupt jumpers
There are two ways to open the chassis to alter the hardware: (1) by
opening the back panel; and (2) by removing the top cover.
Only
boards, fuses, and connectors can be installed by removing the back
panel. You must remove the top cover to make all other hardware
changes.
WARNING
Operators cannot service any parts that can be
reached by removing the chassis back panel
except the cardcage and the boards within it.
Only qualified service personnel should
attempt to do so.
CHANGING HARDWARE WI HOU REMOVING HE COVER
The back panel and the AC panel make up the back of the System 310
chassis.
Components that you are most likely to use, such as the
on/off switch, can be reached from the back. You can install the AC
power plug, change the fuse, or select a different AC line voltage on
the AC power panel; you can change cables and connectors on the
back panel; and, by removing the back panel, you can change the
boards in the cardcage.
CHANGING HE FUSE AND VOL AGE SELEC OR
You must replace the fuse when the fuse is blown or when you change
line voltages. For 100 or 120 VAC lines, use the 6-amp, 250-volt fuse
already installed in your system. For 220 or 240 VAC lines, you must
exchange the 6-amp fuse for a 3~amp, 250-volt fuse, and turn the
voltage selector board.
