Connecting the PTX5000 Packet Transport Switch to an External Alarm-Reporting
Device
To connect an external device to an alarm relay contact on the craft interface:
1. Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and connect
the strap to one of the ESD points on the chassis.
CAUTION: During the initial installation before the chassis is grounded,
you must connect to an approved site ESD point. See the instructions for
your site.
2. Prepare the required length of wire with gauge between 28-AWG and 14-AWG (0.08
and 2.08 mm
2
).
3. While the terminal block is not plugged into the relay contact, use a 2.5-mm flat-blade
screwdriver to loosen the small screws on its side. With the small screws on its side
facing left, insert wires into the slots in the front of the block based on the wiring for
the external device. Connect the major and minor alarm circuits to the NO (normally
open) pins on the alarm connectors. Tighten the screws to secure the wire.
NOTE: The top, middle, and bottom slots correspond to NC (normally
closed), C (common), and NO (normally open).
4. Plug the terminal block into the relay contact, and use a 2.5-mm flat-blade screwdriver
to tighten the screws on the face of the block.
5. Attach the other end of the wires to the external device.

Connecting PIC Cables to the PTX5000 Packet Transport Switch
The PTX5000 Packet Transport Switch supports PICs that use various kinds of network
cable, including multimode and single-mode fiber-optic cable. For information about
the type of cable used by each PIC, see the PTX5000 Packet Transport Switch PIC Guide.
You connect PICs to the network by plugging in network cable. To connect cable to the
PICs (see Figure 40 on page 89:
1. Have ready a length of the type of cable used by the PIC. See the PTX5000 Packet
Transport Switch PIC Guide.
2. If the PIC cable connector port is covered by a rubber safety plug, remove the plug.
