Step 3: Power-Up and Power-Down
To Power Up the Chassis
1. Plug-In Chassis
Using the supplied cord, connect the chassis to an
appropriate AC power main. Use with a ground-fault circuit interrupter (GFCI) is
not recommended.
2. Close Circuit Breaker
Close the rear panel circuit breaker (ON position).

The chassis and host PC must be powered up and down in the following
sequence. The chassis should be powered up first, which will initiate its built-in
Self-Test. During Self-Test, the chassis STATUS LED will be blinking green
(1 s on, 1 s off). The STATUS LED will blink green and then stay green
continuously when the ESM is ready. The ESM then powers up each module
slot. The remote host PC should be turned on only after all installed modules
have performed their initialization—see your module documentation for
initialization information. An embedded controller such as the M9537A handles
this sequence automatically.
The method of powering up the chassis depends on the position of the INHIBIT
switch on the chassis rear panel, which can be set to the DEF (DEFault) position
or to the MAN (MANual) position. Refer to the M9506A User’s Guide for more
information.
