Connecting the ACX500 to External Devices
Connecting ACX500 Routers to Management Devices
To connect external devices and cables to the router, you need the following tools:
RJ-45 Ethernet cable and RJ-45 to DB-9 serial port adapter (provided)
Management host, such as a PC, with an Ethernet port (not provided)
Ensure that you use a waterproof fiber-optic cable with an outer diameter of 10 mm for the SFP ports, and that with an outer diameter of 6.5 mm for the RJ-45 ports.
For the ACX500 outdoor router, see Weatherproofing the ACX500 Outdoor Router topic to know how to access, secure, and weatherproof the router ports. See Front Panel of an ACX500 Outdoor Router to know more about the ports that are available under the management port cover on the ACX500 outdoor router.
When accessing the management ports of the ACX500 outdoor router, ensure to weatherproof the port units by securing back the interface port cover.
Connecting the Router to a Network for Out-of-Band Management
To connect to the
MGMT port on the ACX500 router:
- Turn off the power to the management device.
- Plug one end of the Ethernet cable into the
MGMTport on the router. (Figure 1 shows the connector. Figure 2 shows the port.)
- Plug the other end of the cable into the network device.
Connecting the Router to a Management Console
You can connect a console, laptop, or modem by connecting a
serial cable to the port on the front panel labeled
MGMT. This port accepts a serial cable with an RJ-45 connector, which
is provided with the router.
To connect a management console:
- Turn off the power to the console.
- Plug the RJ-45 end of the serial cable into the
MGMTport on the front panel (Figure 3 shows the connector. Figure 4 shows the ports.)
- Plug the DB-9 socket end into the device's serial port.
For console devices, configure the serial port to the following values:
Bits per second— 9600
Data bits— 8
Stop bits— 1
Flow control— None
Connecting the ACX500 Router to an External Alarm-Reporting Device
To connect the router to external alarm-reporting devices, attach
wires to the
ALARM relay contacts on the front
panel of the router. A system condition that triggers the red or yellow
alarm on the router also activates the corresponding alarm relay contact.
The terminal blocks that plug into the alarm relay contacts are supplied with the router. They accept wire of any gauge between 20 AWG and 14 AWG (0.52 and 2.08 mm2), which is not provided. Use the gauge of wire appropriate for the external device you are connecting.
For the ACX500 outdoor router, see Weatherproofing the ACX500 Outdoor Router topic to know how to access, secure, and weatherproof the router ports.
To connect an external device to an alarm relay contact:
- Prepare the required length of wire with gauge between 8 AWG and 14 AWG (0.08 and 2.08 mm2.
- Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and connect the strap to one of the ESD points on the chassis.
- 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.
- Orient the terminal block according to the labels to the
left of the appropriate relay contact (
NCmeans “normally closed”,
Cmeans “common,” and
NOmeans “normally open”).
- 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.
If you are attaching a reporting device for the other kind of alarm, repeat the procedure.
Connecting the ACX500 Router to External Clocking Devices
The ACX500 routers support external clock synchronization for Synchronous Ethernet, and external inputs.
Connecting 1 PPS Timing Devices to the Router
The two SubMiniature B (SMB, 1 PPS input and 1 PPS output) connectors on the front panel of the router connect to external clock signal sources.
To connect the SMB coaxial cable to the external clocking input port:
- Connect one end of the SMB coaxial cable to the 1 PPS SMB connector on the router.
- Connect the other end of the SMB coaxial cable to the 1 PPS source network equipment.
