Installing a DC Power Supply

Two 300 W DC power supplies are available for use with the E4G-400:
  • Model 10933 can connect to either a –48 V or a +24 V power source.
  • Model 10934A can connect only to a –48 V power source.

We recommend using a Model 10933 power supply, connected to a +24 V power source.

Connecting an E4G-400 router to DC power is a four-step process:

  1. Preparing the DC Cables
  2. Installing the DC Power Supply
  3. Connecting the Ground Cable
  4. Connecting the Power Supply to the DC Source Voltage
Warning

Warning

To prevent an electrical hazard, make sure the DC power cord is disconnected from the power supply before you install the power supply in the power supply bay.
Caution

Caution

Make sure the DC power supply circuit is not overloaded. Use proper precautions, such as a circuit breaker, to prevent overcurrent conditions. Do not use a breaker that is rated for more than 30 A.
