MMAC power supply module and
its access to a live outlet. Check
power cables for viability.
Check that the MMAC has
adequate power. Some
configurations, especially those

that more than one power supply
be installed in the MMAC.
Check to see that all power supply
LEDs are green.
Re-install ESXMIM in hub
according to instructions in
Chapter 3.
Install ESXMIM in a different
MMAC slot.
Examine ESXMIM backplane
connectors for evidence of bent or
broken pins.
Review terminal or emulation
settings for accordance with
requirements.
