Step 9
Use a screwdriver to tighten the two captive installation screws on the supervisor module. Do not over tighten the captive
installation screws.
Step 10
Check the status of the module:
a) Verify that the supervisor module STATUS LED is lit.
b) Periodically check the STATUS LED.
If the STATUS LED changes from amber to green, it means that the supervisor module has completed the boot process
successfully, and is now online.
If the STATUS LED remains amber or turns red, it means that the supervisor module has not completed the boot
process successfully, and may have encountered an error.
c) When the switch is online, enter the
show module
command. Verify that the system acknowledges the new supervisor
module and that the module status is OK.
d) If the module is not operational, reseat it. If the module is still not operational, contact your Cisco customer service
representative.
What to Do Next
Install blank slot cover in empty slots, if any, to maintain consistent airflow through the switch chassis.
Module Interfaces
The supervisor module has the following interfaces or ports: USB ports, console port, management port, and uplink ports.
To avoid electric shock, do not connect safety extra-low voltage (SELV) circuits to telephone-network
voltage (TNV) circuits. LAN ports contain SELV circuits, and WAN ports contain TNV circuits. Some
LAN and WAN ports both use RJ-45 connectors. Use caution when connecting cables.

Console Ports
The supervisor engine front panel provides two types of console ports:
•
USB Console Port
—
This is the USB mini Type B Console Port.
•
10/100/1000 or RJ45 Console Port
—
This console port allows you to access the switch either locally (through a console terminal)
or remotely (through a modem). The console is an EIA/TIA-232 asynchronous, serial connection with hardware flow control
and an RJ-45 connector.
Only one of the consoles is active at a time. When a USB host (PC) is plugged into the USB console port the hardware automatically
switches over to use the USB console. Only a PC which has the necessary USB console device driver causes the USB console to
become active. Plugging in a PC that does not have the USB console driver support does not cause a switchover. When the USB
Cable is removed or the PC deactivates the USB connection, or a host is not detected on the USB console, the hardware automatically
switches to the RJ45 console port.
The console port allows you to perform the following functions:
•
Configure the switch from the CLI
•
Monitor network statistics and errors
