CHAPTER 5: Troubleshooting
The first two sections of this chapter discuss things to try when problems arise in
a ServManager system. If the trouble you’re having with the ServManager is
something you haven’t seen before, or if the trouble seems minor, try the
procedures detailed in
Sections 5.1
and
5.2
before doing anything else.
The third section of this chapter suggests possible causes and solutions to
frequently encountered problems; if the trouble is chronic, see
Section 5.3
.
Sections 5.4
and
5.5
discuss what’s involved in calling Black Box and
shipping your ServManager.
CAUTION!
We strongly recommend that you avoid opening the ServManager’s
cover. If for some reason you need to do this, be very careful to replace
each screw in the same hole you took it from. There are three different
lengths of screws involved, and putting a longer screw in a hole reserved
for a shorter screw can ground the chassis to the circuit boards and
cause serious damage.
5.1 Diagnostic Information
If you’re having difficulty with the ServManager, there is always the possibility
that it has accidentally been configured or set incorrectly. To receive
diagnostic information from a ServManager, including the current settings of
its parameters, take these steps:
1. Establish a remote-control connection with the ServManager as described
in
Sections 4.5.1
and
4.5.2
. (If you want to be able to save or print this
information, or even see the first part of it before it scrolls off the screen,
you should connect the ServManager to a computer running a terminal-
emulator program set to “capture” mode.)
2. Turn OFF the ServManager, then press and hold down the ENTER key
on its front-panel keypad while you turn the ServManager back ON. The
ServManager should immediately begin self-testing and sending ASCII
text of a diagnostic report out of its RS-232 port.
You might want to compare the reported conditions with the default and
possible settings listed in
Appendix A
and the command descriptions in
Sections 4.2
and
4.3
.
