Chapter 1 Product Overview
Alarm Connector
Alarm Connector
You connect the alarm signals to the switch through the alarm connector. The switch supports two alarm
inputs and one alarm output relay. The alarm connector is on the bottom right of the front panel. See
Figure 1-3
.
The alarm connector provides six alarm wire connections. The connector is attached to the switch front
panel with the provided captive screws.

Alarm Connector
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 switch software configuration guide for instructions on configuring the alarm relays.
For more information about the alarm connector, see
Appendix C, “Cable and Connectors.”
SFP Modules Supported
The SFP modules are switch Ethernet SFP modules that provide connections to other devices. Depending
on the switch model, these field-replaceable transceiver modules provide uplink or downlink interfaces.
The modules have LC connectors for fiber-optic connections.
You can use any combination of the supported SFP modules.
