10-Gigabit Ethernet SFP+ Ports
The XE ports described in Table 10 on page 54 support SFP+ transceivers.
NOTE: On the ACX2000 router, you can use Gigabit Ethernet transceivers in the GE ports, or
you can use 10-Gigabit Ethernet transceivers in the XE ports. Use one set of ports at a time. On
the ACX2100 router, you can use both sets at the same time.

ACX2000 and ACX2100 Alarm Contact Port
The ACX2000 and ACX2100 router has four external alarm contacts (also known as potential free contacts)
for connecting the router to external alarm devices. The port labeled ALARM uses a 15-pin D-type
connector. The external alarm contact has 15 pins that accept a single core wire from external alarm
devices. A DE15 alarm cable is required to connect the ACX2000 and ACX2100 router to external alarm
devices. Use the gauge wire appropriate for the external device that you are connecting.
Whenever a system condition triggers an alarm, the alarm relay contacts are activated, which in turn
activates the external alarm devices. The alarm setting is open or closed.
You can connect and configure two output alarms and four input alarms. Two additional output alarms
are reserved and are used to indicate major and minor system alarms. Each output and input alarm has
two contacts for connecting the router to external alarm devices. Contact 1 of each alarm can be configured
as Normally Open [NO] or Normally Closed [NC] through the CLI. Contact 2 of each alarm functions as a
