Alarm Relay Contacts
The craft interface has two alarm relay contacts for connecting the switch to external
alarm devices. Whenever a system condition triggers either the critical (major alarm) or
warning (minor alarm) alarm on the craft interface, the alarm relay contacts are also
activated. The alarm relay contacts are located on the upper right of the craft interface.
Figure 14 on page 25 shows the alarm relay contacts in EX9200 switches.

EX9200-2C-8XS Line Card
The line cards in EX9200 switches combine a Packet Forwarding Engine and Ethernet
interfaces in a single assembly. Line cards are field-replaceable units (FRUs) that you
can install in the line card slots on the front of the switch chassis. Line cards are
hot-insertable and hot-removable: You can remove and replace them without powering
off the switch or disrupting switch functions.
