Connecting the SRX5400 to External Devices

Tools and Parts Required for SRX5400 Services Gateway Connections

To connect the device to management devices and to power on the device, you need the following tools and parts:

• Phillips (+) screwdrivers, numbers 1 and 2

• 2.5-mm flat-blade (-) screwdriver

• 2.5-mm Phillips (+) screwdriver

• Wire cutters

• Pliers

• Electrostatic discharge (ESD) grounding wrist strap

Connecting the SRX5400 Services Gateway to a Management Console or an Auxiliary Device

To use a system console to configure and manage the Routing Engine, connect it to the appropriate CONSOLE port on the Routing Engine. To use a laptop, modem, or other auxiliary device, connect it to the AUX port on the Routing Engine. Both ports accept a cable with an RJ-45 connector. One serial cable with an RJ-45 connector and a DB-9 connector is provided with the services gateway. To connect a device to the CONSOLE port and another device to the AUX port, you must supply an additional cable.

1. Plug the RJ-45 end of the serial cable (Figure 1 shows the connector) into the AUX port or CONSOLE port on the Routing Engine. Figure 2 shows the ports.

   Figure 2: Auxiliary and Console Ports

   

2. Plug the socket DB-9 end into the device's serial port.Note

   For console devices, configure the serial port to the following values:

   • Baud rate—9600

   • Parity—N

   • Data bits—8

   • Stop bits—1

   • Flow control—none

Connecting the SRX5400 Services Gateway to a Network for Out-of-Band Management

1. Plug one end of the Ethernet cable (Figure 3 shows the connector) into the ETHERNET port on the Routing Engine. Figure 4 shows the port.
2. Plug the other end of the cable into the network device.

Connecting an SRX5400 Services Gateway to an External Alarm-Reporting Device

To connect the services gateway to external alarm-reporting devices, attach wires to the MAJOR ALARM and MINOR ALARM relay contacts on the craft interface. (See Figure 5.) A system condition that triggers the major or minor alarm LED on the craft interface also activates the corresponding alarm relay contact.

Figure 5: Alarm Relay Contacts

The terminal blocks that plug into the alarm relay contacts are supplied with the services gateway. They accept wire of any gauge between 28-AWG and 14-AWG (0.08 and 2.08 mm²), which is not provided. Use the gauge of wire appropriate for the external device you are connecting.

1. Prepare the required length of wire with gauge between 28-AWG and 14-AWG (0.08 and 2.08 mm²).
2. 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 top. With the small screws on its top facing upward, insert wires into the slots in the front of the block based on the wiring for the external device. Tighten each screw to secure the corresponding wire.
3. 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. See Figure 6.

4. Attach the other end of the wires to the external device.

To attach a reporting device for the other kind of alarm, repeat the procedure.

Connecting Network Cables to SRX5400 Services Gateway MICs

1. Have ready a length of the type of cable used by the component.
2. Remove the rubber safety plug from the cable connector port.Warning

   Do not look directly into a fiber-optic transceiver or into the ends of fiber-optic cables. Fiber-optic transceivers and fiber-optic cables connected to a transceiver emit laser light that can damage your eyes.

   Caution

   Do not leave a fiber-optic transceiver uncovered except when inserting or removing a cable. The safety cap keeps the port clean and prevents accidental exposure to laser light.

3. Insert the cable connector into the cable connector port on the faceplate.Note

   The transceiver cages and optics on the components are industry standard parts that have limited tactile feedback for insertion of optics and fiber. You need to insert the optics and fiber firmly until the latch is securely in place.

4. Arrange the cable in the standard or extended cable manager to prevent it from dislodging or developing stress points. Secure the cable so that it is not supporting its own weight as it hangs to the floor. Place excess cable out of the way in a neatly coiled loop. Placing fasteners on the loop helps to maintain its shape.Caution

   Avoid bending a fiber-optic cable beyond its minimum bend radius. An arc smaller than a few inches in diameter can damage the cable and cause problems that are difficult to diagnose.

   Caution

   Do not let fiber-optic cables hang free from the connector. Do not allow the fastened loops of a cable to dangle, which stresses the cable at the fastening point.
