The hardware interrupt switch is located on the server's left side (viewed
from the front of the server) near the front, as shown in Figure 1-1 on
page 1-3. The switch is recessed behind a small round hole . Pressing this
switch generates a nonmaskable interrupt (NMI), aborting application
software, disabling all ports except the console port, and passing control to
the monitor utility. For information on the monitor utility, refer to Chapter 4,
"Configuration," and Appendix C, "Monitor Utility."
If the server crashes or stops working entirely, you may need to use the
hardware interrupt switch to reboot or to perform a memory dump. For
information on memory dumps, refer to "Memory Dump Procedures".
WARNING: Use only a nonconductive object such as a plastic stylus to press
the hardware interrupt switch. Do not use the tip of a pencil. Graphite
particles can cause electrical shock to the operator and can damage
components on the server's circuit boards.
The inverted U-shaped cover is secured by three screws on the bottom
edge of each side of the chassis.
Both sides of the cover have vents. The vents on the left side (viewed from
the front of the server) are for air intake. The vents on the right side are for
air exhaust.
The front panel of the server includes the following:
Six LEDs
Reset switch
Internal 3.5-inch diskette drive (Model CS/3100 only)
Figure 1-3 shows the front panel of Model CS/3100. Model CS/3000 is
identical except for the diskette drive.
