Chapter 3. Operating the M12
This chapter describes how to operate the M12 and includes the following
information:
v “Turning the switch on and off”
v
“Interpreting LED activity” on page 20
v “Interpreting POST” on page 30
v
“Maintaining the switch” on page 31
Note: Throughout this chapter, the term switch refers to the M12.
Turning the switch on and off
To turn the switch on, verify that both power cords connect to the ac power
connectors on the front of the chassis. Flip both green ac power switches to “|”. The
green ac power switches illuminate when they are on.
To turn off the switch, flip both ac power switches to “O”. To remove all sources of
power from the switch, disconnect both power cords from the power source.
Note: Removing all power from the switch triggers a system reset. When you
restore the power, all devices return to the initial state, and the switch runs a
POST.
Attention: After you power on the switch, run it for a minimum of 10 minutes
before you power off again.

Attention: Wear an electrostatic discharge (ESD) grounding strap when you work
with a 16–port card to prevent damage to the electrical components.
To ensure correct cooling of the chassis and protection from dust, install a filler
panel in any slots that do not contain a 16–port card.
Disassembling any part of a 16–port card voids the part warranty and regulatory
certifications.
