The alarm connector provides six alarm wire connections. The connector is attached to the switch front panel with the
provided captive screws.

Both alarm input circuits can sense if the alarm input is open or closed. The alarm inputs can be activated for
environmental, power supply, and port status alarm conditions. From the CLI, you can configure each alarm input as an
open or closed contact.
The alarm output circuit is a relay with a normally open and a normally closed contact. The switch is configured to detect
faults that are used to energize the relay coil and change the state on both of the relay contacts: normally open contacts
close, and normally closed contacts open. The alarm output relay can be used to control an external alarm device, such
as a bell or a light.
See the Cisco Connected Grid Switches System Management Software Configuration Guide for instructions on
configuring the alarm relays.

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 mini-Type B console port, also referred to as the USB-mini console port. These ports use the following
connectors:
RJ-45 console port uses an RJ-45-to-DB-9 female cable.
USB-mini console port (5-pin connector) uses a USB Type A-to-5-pin mini-Type B cable.
The USB-mini console interface speeds are the same as the RJ-45 console interface speeds.
To use the USB-mini console port, you must install the Cisco Windows USB device driver on the device that is connected
to the USB-mini console port and that is running Microsoft Windows.
Note:
For information about downloading the Cisco USB device driver, see the
USB Device Driver, page
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 requires no special drivers.
Note:
The 5-pin mini-Type B connectors resemble the 4-pin mini-Type B connectors, but they are not compatible. Use
only the 5-pin mini-Type B. See
