Rev. B, April, 2016
The following commands allow the safe removal of a Control Card and the switch of activity from one
Control Card to the other without interruption of connections
Note: During normal operation, the Primary Control Card should always be the active
controller for the system.
During normal operation the Primary or Secondary Controller can be managed via the console port or over
an SSH connection.
The HALT Command
Typing
halt
at the command line will perform an orderly shut-down of the active Control
Card.
Once the Control Card is inactive, it will stop signaling the other Control Card. This prompts
the other card to become active. This will take only a few seconds.
Remove any cables (LAN, RS-232, Console, etc.) from the inactive card. It can now be
safely removed from the chassis.
At this point, the system is now running on the Secondary Control Card.
Note: Re-inserting the Primary Control Card restores the system back to running on the
Primary Control Card. Insure that the LAN connection to the card is restored promptly.
The PWROFF Command
Typing
pwroff
at the command line prompt, from either the Primary or the Secondary
Control Card, will halt BOTH Control Cards and turn off the power to all the I/O card slots
in the system except the controllers.
Note: I/O card slot power cannot be turned off on the TLX48.
Remove the AC power cord(s) from the Matrix Switch or from the AC source for a complete
system shut-down.
Remove any cables (LAN, RS-232, Console, etc.) from the Control Cards.
The Control Cards can now be removed, swapped or replaced as needed.
Upon turn-on, the Control Card in the top or the left slot will become Primary and the Card in either the
bottom or the right slot will be the Secondary back-up.
