Console/Modem Port.
The CMM’s
front panel provides one RS232 port for
console or modem connections. By
default, this female DB-9 connector
provides a DCE console connection.
However, by changing the onboard
jumper setting, the port can be changed
to a DTE modem connection.
For detailed information on changing
the jumper setting, refer to
.
Ethernet Management Port.
The
CMM’s front panel also provides one
Ethernet 10/100BaseT port (Copper
RJ45). Provides out-of-band network
management and can be used for Telnet
sessions, switch diagnostics, and for
downloading software to the switch.
This 10/100BaseT port supports both
10BaseT and 100BaseT with auto-
negotiation through the RJ45 connector.
Note:
In redundant CMM configura-
tions, the EMP is only operational on
the
primary
CMM. For more informa-
tion on redundant CMM configurations,
refer to
Ethernet Management Port LEDs
LINK.
Link Integrity Status. Displays solid
green when an Ethernet cable connection exists
at the CMM’s Ethernet management port.
ACT.
Flashes green as data is transmitted or
received on the CMM’s Ethernet management
port.
Module Status LEDs
OK1.
Hardware Status. Displays solid green
when powered on and the CMM has passed
hardware diagnostic tests. Displays solid amber
when powered on and the CMM has failed hard-
ware diagnostic tests.
OK2.
Software Status. Blinks green when the
CMM is operational. Displays solid amber when
a system software failure occurs. Blinks amber
when the software is in a transitional state (e.g.,
when software is being downloaded to the
switch).
Redundancy LEDs
PRI.
Displays solid green when the CMM is the
primary (active) management module.
SEC.
Displays solid green when the CMM is
the secondary (backup) management module.
For detailed information on CMM redundancy,
refer to
Temperature/Fan Status LEDs
TEMP.
Displays solid green when the CMM is
operating within the allowed temperature range.
Displays solid amber if a temperature error
occurs (i.e., the CMM is operating outside the
temperature range).
If the LED indicates a temperature error, you
can use the
show temperature
command to
access more information. Refer to the
CLI Ref-
erence Guide
for more information.
FAN.
Displays solid green when all fans in the
fan tray are running at normal speed. Displays
solid amber if a fan error occurs (i.e., one or
more fans are not running at normal speed).
If the LED indicates a fan error, you can use the
show fan
command to access more information.
Refer to the
CLI Reference Guide
for more
information.
