Connecting the Router

This chapter contains the following sections:

Overview of the IR1800 Connecting Process

This chapter describes how to connect the IR1800 to Ground, Power, Ethernet devices and a network.

Preparing to Connect the Router

Before you connect the router to the devices, install the router according to the instructions in Installing the Router.

Preventing Damage to the Router

To prevent damage to your router, turn off the power to the devices and to the router until all connections are completed.

For hazardous location environments, follow these warnings when connecting to destination ports (antenna, serial, Ethernet, and console ports).


Warning
If you connect or disconnect the console cable with power applied to the switch or any device on the network, an electrical arc can occur. This could cause an explosion in hazardous location installations. Be sure that power is removed or the area is nonhazardous before proceeding. Statement 1080

Warning
Do not connect or disconnect cables to the ports while power is applied to the switch or any device on the network because an electrical arc can occur. This could cause an explosion in hazardous location installations. Be sure that power is removed from the switch and cannot be accidentally be turned on, or verify that the area is nonhazardous before proceeding. Statement 1070

Caution

Do not turn on the devices until you have completed all the connections to the router.

Connecting a PC, Server, or Workstation

To connect a PC (or other Ethernet devices) to an Ethernet switch port, follow these steps.

Procedure

Step 1

Connect one end of the Ethernet cable to an Ethernet switch port on the router.

Step 2

Connect the other end of the cable to the RJ-45 port on the network interface card (NIC) that is installed in the PC, server, or workstation.

Step 3

(Optional) Connect additional servers, PCs, or workstations to the other Ethernet switch ports.

Connecting a PC to the Console Port

Connect a PC to the console port either to configure the software by using the CLI, or to troubleshoot problems with the router.

To connect a terminal or PC to the console port on the router and access the CLI, follow these steps:

Procedure

Step 1

Connect the Micro-B USB console cable to the console port on the router.

Step 2

Connect the opposite end of the micro-USB cable to the USB port on your laptop or PC.

Step 3

To communicate with the router, wait for your laptop or PC to discover the new device.

Step 4

If your laptop or PC warns you that you do not have the proper drivers to communicate with the router, you can obtain them from your computer manufacturer or from this location:

Connecting to DC Power and CAN Bus Wiring


Warning
This product relies on the building’s installation for short-circuit (overcurrent) protection. Ensure that the protective device is rated not greater than 60 VDC minimum, 5A maximum. Statement 1005

Warning
Connect the unit only to DC power source that complies with the safety extra-low voltage (SELV) requirements in IEC 60950 and IEC 62368 based safety standards. Statement 1033

Warning
This product requires short-circuit (overcurrent) protection, to be provided as part of the building installation. Install only in accordance with national and local wiring regulations. Statement 1045

Warning
When you connect or disconnect the power and/or alarm connector with power applied, an electrical arc can occur. This could cause an explosion in hazardous area installations. Be sure that all power is removed from the switch and any other circuits. Be sure that power cannot be accidentally turned on or verify that the area is nonhazardous before proceeding. Statement 1058

Warning
Explosion Hazard—The area must be known to be nonhazardous before installing, servicing, or replacing the unit.Statement 1082

Warning
Explosion Hazard—Substitution of components may impair suitability for Class I, Division 2/Zone 2.Statement 1083

Plugs and Pinouts

The IR1800 uses a DC power accessory kit (part number PWR-MF4-125W-AC). This needs to be ordered separately. The power entry receptacle is on the IR1800. The pinouts are shown in the following figure.

The IR1800 can be installed without connecting to the CAN Bus. There is a 2-wire cable that can be ordered (CAB-PWR-15-MF4). The following is a diagram of the cable:

Verifying Connections

To verify that all the devices are properly connected to the router, turn on all the connected devices, and then check the LEDs.
