The alarm input is a dry-contact alarm port. You can connect up to four alarm inputs from devices, such 
as a door, a temperature gauge, or a fire alarm, to the alarm port. You can use the CLI to set the alarm 
severity to minor, major, or critical. An alarm generates a system message and turns on an LED. See the 

 for the LED descriptions.

The alarm output can be configured as a minor or major alarm. Output alarms often control an external 
alarm, such as a bell or a light. To connect an external alarm device to the relay, you connect two relay 
contact wires to complete the electrical circuit. See 

 for information on the alarm 

pinouts.

You can connect the switch to a PC running Microsoft Windows or to a terminal server through either 
the RJ-45 console port or the USB console port. 

RJ-45 console port. The RJ-45 connection uses an RJ-45-to-DB-9 female cable.

USB mini-Type B console port (5-pin connector). The USB connection uses a USB Type A-to-5-pin 
mini-Type B cable. 

The USB console interface speeds are the same as the RJ-45 console interface speeds.

To use the USB console port, you must install the Cisco Windows USB device driver on the device that 
is connected to the USB console port (device running with Microsoft Windows). 

For information about downloading the Cisco USB device driver, see the 

With the Cisco Windows USB device driver, connecting and disconnecting the USB cable from the 
console port does not affect Windows HyperTerminal operations. Mac OS X or Linux require no special 
drivers. 

The 5-pin mini-Type B connectors resemble the 4-pin mini-Type B connectors. They are not compatible. 
Use only the 5-pin mini-Type B. See 

.

The configurable inactivity timeout reactivates the RJ-45 console port if the USB console port is 
activated, but no input activity occurs on it for a specified time period. When the USB console port 
deactivates due to a timeout, you can restore its operation by disconnecting and reconnecting the USB 
cable. For information on using the CLI to configure the USB console interface, see the switch software 
guide.
