Rev. H, February 2020
During normal operation the Primary or Back-up 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 Back-up Control Card.
Note: Re-inserting the Primary Control Card restores the system back to running
on the Primary Control Card. Ensure 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 Back-up
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 will be turned off on the TLX640.
•
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 Back-up.
How to Install and Replace Modules
How to Install or Replace an Input / Output Card
Note: No shutdown is required prior to installing/replacing Input/Output
Cards.
1
Turn the
card’s two thumbscrews counterclockwise until they disengage from the chassis.
Pull the card straight out using both handles.
Do not pull on the thumbscrews when
removing the module
– damage may occur! Use the handles!
2
Place the new module upright so that the POWER LED is on the top. Grasp the
module by the handles. The card should slide freely until it reaches the backplane
connector. At this point, use just enough force to firmly engage the card with the mating
connector.
If the module does not slide into the connector, do not force it!
Damage may occur. Remove the card and start over.
3
Once the module is completely seated, hand-tighten the thumbscrews.
Do not tighten
the thumbscrews with a screwdriver.
