8 Installing Your Switch
The Console Management ports are
RS-232
ports used
to interface with switch software. One port, called the
“modem” port, is a male
DTE
connector and the other,
called the “console” port, is a female
DTE
connector.
They are each 9-pin “D” (
DB-9
) connectors that
conform to the
IBM AT
serial port specification. If the
connecting device does not conform to the
IBM AT
serial port specification, you may need a special cable
or adapter.
7. Power On the Switch
Turn the power supply On/Off switch to the On (I)
position.
8. Verify LEDs
Check that
LED
s on the front panel of the chassis indi-
cate a normal state of operation. On an
MPX,
the
PS1
LED
should be on steady Green if one power supply is
inserted. If two power supplies are installed, both the
PS1
and
PS2
LEDs
should be on solid Green.
All modules are subjected to extensive power-on diag-
nostics during the Power-On Self-Test cycle (
POST
). For
this reason, you should allow the switch several
seconds to perform preliminary tests before evaluating
the
LEDs
. While the diagnostics are running, the
MPX
OK2
LED
will blink Amber. When diagnostics are
complete and all modules are operating correctly, the
OK1
LED
on all modules should be on solid Green and
the
OK2
LED
should be blinking Green. The tables
below summarize how
LED
s should display in normal
operation.
