NOTE
For the NEBS-compliant installation, AC power connections must use a surge protection device (SPD) to protect the AC power
supplies from damage due to excessive power line surges.
Follow these steps to connect the AC power cord.
1. Locate the power supply AC inlet on rear of chassis for the associated installed power supply.
2. Lift the cord retainer and connect the AC power cord to the AC inlet.
3. Snap the cord retainer over the power plug to hold it in place.
DANGER
If the installation requires a dierent power cord than the one supplied with the device, make sure you use a
power cord displaying the mark of the safety agency that denes the regulations for power cords in your country.
The mark is your assurance that the power cord can be used safely with the device.
For information about powering on the system, refer to Activating the power source on page 172.
Connecting DC power
You can provide DC power for the router by installing a DC-to-DC power supply. The DC-to-DC supply converts 48V-DC input from a
power source to 12V-DC for your router.
DANGER
The procedures in this manual are for qualied service personnel.
NOTE
Because there are multiple power supply vendors, the LED layout on your DC power supply may dier from what is shown in
the following gure. However, the LED functions are identical.
NOTE
The 1200W and the 1800W power supplies are for use with the MLXe-4, MLXe-8, and MLXe-16 routers.
