Entering the Monitor C-3
If an error occurs while the server is running its software, the server
automatically accesses the monitor. At this point, 3Com or your network
supplier may ask you to perform a memory dump. For information on
memory dumps, refer to “Memory Dump Procedures” on page 6-5.
Using the Hardware
Interrupt Switch
You can use this method of accessing the monitor even if the server
becomes nonfunctional.
CAUTION: Do not press the hardware interrupt switch while the Self
Test LED is on. Doing so can corrupt memory or firmware
configurations. This LED can take up to a minute to go out.
Using a nonconductive object such as a plastic stylus, press the hardware
interrupt switch. The hardware interrupt switch is located on the server’s
left side (viewed from the front of the server) close to the rear, as shown
in Figure 1-2 on page 1-4. The switch is recessed into a round hole to
protect it from being pressed unintentionally.
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 following message appears:

>
If you are pressing the hardware interrupt switch because the server has
become nonfunctional, enter the following command:
k
Entering this command performs a soft reset, which resets the monitor’s
stack and internal variables and the Ethernet and serial controllers. At
this point, 3Com or your network supplier may ask you to perform a
memory dump. For information on memory dumps, refer to “Memory
Dump Procedures” on page 6-5.
