Powering on and off
Powering on and off switch modules and pass-through
cards
Switch modules and pass-through cards installed in the Blade Enclosure can be powered on and off
in one of two ways. Power on connected peripheral equipment first and then power on the modules
and/or pass-through cards. For information on status or confirmation after switch modules and/or
pass-through cards are powered on, see "Checking operations" in "Command line interface (CLI)
(EM card)."
Powering on from the Blade Enclosure
When the Blade Enclosure is powered on by rack power-on, switch modules and pass-through
cards installed in the Blade Enclosure are automatically powered on. Replacement switch modules
and pass-through cards are also powered on automatically if the replacement is done with the Blade
Enclosure powered on. (For information on powering on the Blade Enclosure, see the User‟s Guide
of the Blade Enclosure.)
Powering on by using the command line interface (CLI) of the EM card
Switch modules and pass-through cards installed in the Blade Enclosure can be powered on and off
by using the command line interface (CLI) of the EM card.
This section describes how to power on and off a CPU blade by using the CLI. For information on
the CLI, see "Command-line interface (CLI) (EM card)" and "How to describe a command" in the
User‟s Guide of the Blade Enclosure. You can connect to the CLI either through a telnet connection
or through the serial port. For information on connecting to the CLI, see the User‟s Guide of the
Blade Enclosure.
