Connecting the EX9200 to External Devices
Connecting an EX9200 Switch to a Network for Out-of-Band Management
You can monitor and manage an EX9200 switch by using a dedicated management channel. Each switch has an Ethernet management port labeled with an RJ-45 connector for out-of-band management. Use the Ethernet management port to connect the EX9200 switch to the management device.
Ensure that you have an Ethernet cable with an RJ-45 connector available. One such cable is provided with the switch. Figure 1 shows the RJ-45 connector of the Ethernet cable supplied with the switch.
To connect a switch to a network for out-of-band management:
- Turn off the power to the management device.
Connect one end of the Ethernet cable to the management port.
In an EX9200 switch, the management port is on the Routing Engine module (RE module) installed in the switch and is labeled
ETHERNET(see Figure 2).
- Connect the other end of the Ethernet cable to the management device.
Connecting an EX9200 Switch 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 labeled
CONSOLE on the Routing Engine module (RE module) in an
EX9200 switch. To use a laptop, modem, or other auxiliary device,
connect it to the auxiliary (labeled
on the RE module or front panel. 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 switch. To connect a device to the
console port and another device to the auxiliary port, you must supply
an additional cable.
Ensure that you have an Ethernet cable with an RJ-45 connector available. An RJ-45 cable and an RJ-45 to DB-9 serial port adapter are supplied with the device.
Figure 3 shows the RJ-45 connector of the Ethernet cable supplied with the switch.
If your laptop or PC does not have a DB-9 plug connector pin and you want to connect your laptop or PC directly to the device, use a combination of the RJ-45 to DB-9 socket adapter supplied with the device and a USB to DB-9 plug adapter. You must provide the USB to DB-9 plug adapter.
To connect the device to a management console or auxiliary device:
- Turn off the power to the console or auxiliary device.
- Plug the RJ-45 end of the serial cable into the auxiliary
port or console port on an EX9200 switch. Figure 4 shows location
CONSOLEports on an RE module in an EX9200 switch.
- Plug the socket DB-9 end into the serial port of the switch.
Connecting the EX9200 Switch to an External Alarm-Reporting Device
To connect the switch to external alarm-reporting devices, attach
wires to the
MAJOR ALARM and
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.
The terminal blocks that plug into the alarm relay contacts are supplied with the switch. They accept wire of any gauge between 28 AWG (0.08 mm2) and 14 AWG (2.08 mm2), which is not provided. Use the gauge of wire appropriate for the external device you are connecting.
To connect an external device to an alarm relay contact (see Figure 5):
- Prepare the required length of wire with gauge between 28 AWG (0.08 mm2) and 14 AWG (2.08 mm2).
- 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. Tighten the screws to secure the wire.
- 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.
- 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.
