5 Installing the Router

Scenario 1: Installing the Router on a DIN Rail
Before You Start
Before the installation, ensure that the DIN rail has been secured in position.
The router is placed near the DIN rail for convenient movement.
Installation Procedure
Step 1 Place the router's real panel in front of the DIN rail and
ensure that the DIN rail fits in between the fixture near the
top of the router and spring latch near the bottom.
Step 2
Make the router incline forward with the bottom away
from the DIN rail, and place the fixture at the rear of the
router on the top of the DIN rail.
Step 3 Slowly push the router toward the DIN rail to make the
spring latch at the rear of the router move down. The
spring latch then bounces back to fix the router on the DIN
rail.
NOTE
If the spring latch is too tight to move down, you can pull down the spring latch during the installation.
Scenario 2: Installing the Router in a Cabinet (Using a 550 Horizontal Rack-Mounting Kit)
Before You Start
There must be a clearance larger than or equal to the router's width at the left and right of the router after the
installation. The clearance above the router must be at least two times the router's height and the clearance
below the router must be greater than or equal to the router's height.
