Disconnecting the Alarm Relay Wires from the Craft Interface in an EX9200 Switch
The craft interface has two alarm relay contacts for connecting the switch to external
alarm devices (see Figure 88 on page 262).
Ensure that you have the following parts and tools available:
•
Electrostatic discharge (ESD) grounding strap
•
2.5-mm flat-blade (–) screwdriver
To disconnect the alarm relay wires from the switch and the alarm-reporting device:
1. Disconnect the wire at the external device.
2. Attach an ESD grounding strap to your bare wrist, and connect the strap to one of the
ESD points on the chassis.
3. Loosen the small screws on the face of the terminal block using a screwdriver and
remove the block from the relay contact.
4. Loosen the small screws on the side of the terminal block using a screwdriver. Remove
existing wires from the slots in the front of the block.
