How to Remove and Replace a Power Supply Module
Each Power Module is universal input 120-240VAC, 50-60Hz. Use the proper power cords for your
region. (Two PWR-000056-R power cords are supplied with the unit).
Warning!
Disconnect the power cord before proceeding!
Note: If only ONE power supply is installed, shutdown IS
required. If TWO power supplies are installed and only one is
being replaced, shutdown IS NOT required.
The Power Modules are universal input 120-240VAC 50-60Hz. Use the
proper power cords for your region (PWR-000056-R, supplied with the
unit).
Although the TLX160 functions properly with one Power
Module, it is recommended that the Primary and Secondary be
connected to two independent power sources for redundancy.
Step 1
Lift the green latch tab.
Step 2
While holding the tab up, pull the Power Module straight out of
the chassis by the handle.
Step 3
Insert the new Power Module into the chassis and slide it in
until it reaches the backplane connector. At this point, use just enough
force to firmly engage the module with the rear mating connector.
Warning!
If the module does not slide easily into the connector, do not force it! Damage
may occur. Remove the module, reseat it, and start over.
How to Safely Remove an Active Controller Card or Shut Down the System
During normal, non-maintenance operation, the
Primary Control Card should always be the Active
controller for the system.
However, there may be times when other conditions temporarily exist, such
as during maintenance, updates, repairs, etc.
Although the system will run normally on the Secondary Control Card, not having a second card
eliminates the fail-over protection afforded by a redundant, two-card system.
The following methods allow the safe removal of one or both Control Cards.
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 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.
•
The Controller Cards’ 3.3V stand-by voltage remains on, even after issuing a
pwroff
.
•
For a complete system shut-down, remove the AC power cord(s) from the Matrix Switch or from
the AC source.
In addition to the
PWROFF
command, the system can be safely shut down by pressing the HALT buttons.
The HALT Button
•
Each Controller Card has a HALT button for controlled shut-down. (
See pg. 7 for specific
operation of one or both HALT buttons.
)
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.
