| Install the Router. |
There are three steps to installing your router:
![]() | Warning Hazardous network voltages are present in WAN interface card ports regardless of whether power to the router is OFF or ON. To avoid electric shock, use caution when working near WAN ports. When detaching cables, detach the end away from the router first. |
A. Connect the router to your local Ethernet network(s). The router can be connected to one or two local networks.
B. Install a WAN interface card. The router cannot make any connections outside the local network unless a WAN interface card is installed and connected. Without a WAN interface card installed, the router does function correctly between two local networks.
C. Connect the power supply. After you connect the power, you can confirm proper installation by checking that certain LEDs are on.
| Install the Router (continued). |
The router has three Ethernet ports, but supports only two Ethernet connections at one time. Connect the router to your local Ethernet networks in one of these ways:
Option 1: Connect the ETHERNET Ø 10BASET port and the ETHERNET 1 10BASET port.
Option 2: Connect the ETHERNET Ø AUI port and the ETHERNET 1 10BASET port.
You need two RJ-45-to-RJ-45 cables and two Ethernet hubs or switches for this option.
Step 1 Connect one end of the first cable to the yellow ETHERNET Ø 10BASET port, and connect the other end to a network port on the hub or switch.
Step 2 Connect the second cable to the yellow ETHERNET 1 10BASET port as described in Step 1
.
You need one RJ-45-to-RJ-45 cable, one AUI cable, and an Ethernet transceiver for this option. If the transceiver connects directly to the router, you do not need the AUI cable.
Step 1 Connect the Ethernet transceiver to the yellow ETHERNET Ø AUI port, and connect the transceiver to the local network.
Step 2 Connect one end of the RJ-45 cable to the yellow ETHERNET 1 10BASET port, and connect the other end to a network port on the hub or switch.

Look for a WAN interface card in the slot on the right-rear of the router, just above the slot labeled FLASH PC CARD. (There is no WAN interface card installed if there is a metal plate over the slot.) If the card is already installed, connect it to your WAN line according to the instructions that came with the card. To install a card, follow the instructions below.
Step 1 Confirm that the power is OFF.
Step 2 Remove the thumbscrews that hold the slot cover in place, and then remove the slot cover.
Step 3 Hold the card by the edges and line it up with the guide on the card slot.
Step 4 Insert the card into the slot and push in until it is firmly seated in the connector and the front panel is flush with the router rear panel.
Step 5 Tighten the screws that are in the card.
Connect the card port to the WAN line according to the instructions that came with the card.


| Install the Router (continued). |
After connecting the router to power and turning it on, you can confirm that you have installed the router correctly by checking certain LEDs. Connect the router to the power supply as shown below. Depending on where you are installing the router, your power supply and power outlet could be different from those in the picture.
Step 1 Connect the power supply cord to the power socket on the rear panel.
Step 2 Connect the power supply to a power outlet.
Confirm that the router has power by checking that the SYSTEM PWR LED on the front panel is on.
Step 3 Confirm that the router has power by checking that the SYSTEM PWR LED on the front panel is on.

| Verify Your Installation. |
| LED | Location | What to Look For |
|---|---|---|
SYSTEM PWR | Front | On means that power is being supplied to the router. |
SYSTEM OK | Front | On means that the router software is loaded and functional. Blinking means that the software is being loaded into router memory. |
OK | Rear, to the left of the Flash PC card slot | On means that the Flash PC card is correctly installed. If the LED is off, refer to the hardware installation guide that came with the router for instructions on how to re-install the card. |
LNK | Rear, one next to each 10BaseT port | On means that the router is connected to a local Ethernet network through this port. If you connected the router to a local network through the AUI port, then the LNK LED next to the ETHERNET Ø 10BASET should be off. |
ETHØ ACT | Front | Blinking means that there is network traffic on the local Ethernet network that is connected to the ETHERNET Ø 10BASET port or the ETHERNET Ø AUI port (only one of these two ports should be connected). |
ETH1 ACT | Front | Blinking means that there is network traffic on the local Ethernet network that is connected to the ETHERNET 1 10BASET port. |
Any WAN interface card LEDs | WAN interface card front panel | Refer to the documentation that came with the WAN interface card. |
