Alarm Output
The alarm output can be configured as a 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. For for information on the alarm pinouts. see Alarm Port, on page 64.
Console Port
You can connect the router to a PC running Microsoft Windows or to a terminal server through the RJ-45
console port. The RJ-45 connection uses an RJ-45-to-DB-9 female cable.
Power-Input Terminal
The power-input terminal provides screw terminals for the AC and DC power connections. The router can
operate with one or two power supplies. If one of the power sources fail, the other continues to power the
router. See Power Supply Installation, on page 33 for more information.
100/1000 SFP Ports (Uplinks)
The uplink ports support 100M optics and 1G optics. When using a 1000BaseT SFP, the port only operates
at 1000 mbps.
100/1000 SFP Ports (Downlinks)
The router Ethernet SFP modules provide connections to other devices. These field-replaceable transceiver
modules provide the downlink interfaces. The IR8340 router supports both FE and GE optics in the downlinks.
SFP modules have local connectors (LCs) for fiber-optic connections.
For information about SFP modules, see your SFP module documentation. For more information about SFP
modules and cables, see Transceiver Modules .
The small form factor pluggable (SFP) ports on the Cisco IR8340 router support the following SFP modules:
