MMAC-Plus Installation Guide

Powering up the MMAC-Plus

The MMAC-Plus chassis is powered up by following the steps below:

1. Plug one end of the power cord (supplied with the power supply) into the AC

power socket on the lower right front corner of the power supply.

2. Plug the other end of the power cord into an AC receptacle. Turn on the

power supply using the switch located near the power socket.

3. The power supply uses a soft start feature and does a pre-power diagnostic

check. Outputs become enabled within 5 seconds of turning the power on.

4. Check that the PWR and SMB LEDs on the power supply are green.

If the LEDs are any color other than green, refer to the

Power Supply User’s

Guide

5. Check that all LEDs on the INB Terminator Module are green.

If the LEDs are any color other than green, refer to the

INB Terminator

Module Installation Guide

6. Check that the Status and Alarm LEDs on the Environmental Module are

green.

If the LEDs are not green, refer to the

Environmental Module User’s Guide

7. Check that the System Management Bus (SMB) and the Board OK (BOK)

LEDs on the front panel of each installed Interface Module are green. (Be sure

the boards have completed booting; this may take up to 20 seconds.)

If an Interface Module’s SMB and BOK LEDs are not green, refer to the User’s

Guide for that Interface Module.
