Powering on the Router
Connect AC Power to the Chassis

We recommend that you occupy all power supply slots of the router with power supplies. In case a power
module fails, it is recommended to retain the failed power module in its slot until it is replaced with a new
power module. This recommendation ensures that the system airflow is not impacted adversely, which may
then result in the overheating of the router and its components.
Note
A dual pole breaker is needed for installation. For determining the recommended breaker size, please adhere
to local and national rules and regulations. The breaker size is based on the specifications of the product for
the current drawn and the specified voltage level.
Note
Procedure
Step 1 Verify that the AC cable is installed in the correct AC source and outlet type.
Step 2 Set the AC-input power supply switch to the OFF (0) position.

Connect a DC Power Supply to the Chassis
When installing a DC-input Power Supply Unit (PSU), you will need access to the terminal block of the PSU
in order to connect the DC-input wires. If the front panel of the chassis has limited access because of other
interfering cables, consider connecting the DC-input wires to the terminal block, before you install the PSU
in the chassis. If you do have clear access to the terminal block, you can install the PSU in the chassis first
and then connect the DC-input wires.
The procedure to install the module in the chassis and the procedure to connect the DC-input wires have been
described in Connecting the DC-Input Wires, on page 17. You can complete either task first and then move
on to the next, and finally power up the PSU.
Install a DC Power Supply Unit in the Chassis
The power button has two modes of operation, which are described below. Press the power button for 10
seconds to toggle between modes; the LOCATE LED blinks for three seconds when you do.
• Auto-on: When in this mode, the power supply module automatically starts or restarts on application or
restoration of DC input power. This is the default mode.
For NEBS compliance, the power button must be in the auto-on mode. When power is restored after a
power failure, the power supply module recovers automatically.
• Protected: When in this mode, if the DC power source output voltage is zero, or drops out for more than
three seconds, you must press the power button for two seconds, to restore operation.
Note
To install a DC-input Power Supply Unit (PSU) in the chassis, follow the steps described here.

Step 3 Grasp the terminal block with one hand. Place your other hand underneath as you slide the PSU into the bay.
You will hear an audible click sound, which indicates that the module is locked into place, and connected
with the backplane. Only the terminal block housing is not flush with the chassis.
If you do not push the release latch in before you slide the module into the bay, you will not hear the click
sound, but this is an acceptable way of installing the module.
If the module is properly locked in place, you should not be able to remove the module without releasing the
latch.

Warning
Statement 1073—No User-Serviceable Parts
There are no serviceable parts inside. To avoid risk of electric shock, do not open.
Warning
Procedure
Step 1 Locate the circuit breaker on the panel board that services the DC circuit, and switch the circuit breaker to
the OFF position.
Step 2 Prepare the DC-input wires and the grounding wire. Crimp the lugs to the cable ends according to the lug
manufacturer’s direction and your local electrical codes for installation.
Use a heat-shrink sleeve to ensure that there is no exposed wiring extending from the terminal block, when
installed.
If you are using cables of different colors for your DC-input wires, we recommend one color for all the positive
circuits, a second color for all the negative circuits, and a third color, which is normally solid green or green
with yellow stripes, for the safety ground connection.
Step 3 Using a number one Phillips screwdriver, loosen the captive installation screw on the terminal block cover.
Step 4 Using a nut driver, loosen and remove the two nuts in the terminal slot meant for grounding, and set them
aside.
The nut driver you are using must have at least a three-inch shaft, to clear the height of the terminal block
cover and enable you to loosen or tighten the nuts in the terminal slots.
Statement 1046—Installing or Replacing the Unit
To reduce risk of electric shock, when installing or replacing the unit, the ground connection
must always be made first and disconnected last.
