For NCS-57B1 fan modules, hold the fan module with the LED and PID label at the top.
Step 4
For NCS-57C3-MOD fan trays, hold the fan tray with the latch on the right.
Step 5
Align the fan module or fan tray to the open fan slot in the chassis and press the module all the way into the slot until the
latches click and lock on the chassis.
On the NCS-57C3-MOD, the 2x60mm fan trays (NC57-C3-FAN2-FW) have alignments guides along the right

Step 6
If the chassis is powered on, listen for the fans. You should immediately hear them in operation. If you do not hear them,
ensure that the fan module is inserted completely in the chassis.
Step 7
Verify that the fan module LED is green. If the LED is not green, one or more fans are faulty.
After installation, we recommend that you move the fan handles to the right side so that the fan module LED
is visible.
Note
Replace Power Supply
The router provides the choice of two different power supplies:
• DC power—The DC power supply uses 2-position terminal block-style connector with positive
latching/securing and labeled connections for +24/48V, GRD, -24/48V. The terminal block connector
is of suitable size to carry the appropriate AWG wire size to handle the input current of the power supply.
No ON/OFF switch is provided.
