If
the power available is too low to meet the requirements of the MUX at
each voltage level, you must augment the computer power supply, or
remove another board before installing the card. Contact your HP Sales
and Support Office for details.
Refer to the System Installation and Configuration Guide included with
your system for the proper placement and positioning of the card.
Before attempting to install this (or any) peA, follow the computer "shut .
down" procedure and TURN OFF the computer power supply. Failure
to
disconnect the current could result in an electrical shock, and it may
damage both the computer and the card. Any resultant damage will not
be covered by warranty.
The 27140A MUX card uses friction at the backplane contacts to hold the
card in place. Hold the card firmly by the extractor levers and gently push
it into the track-like guides of the slot. Once the card touches the back-
plane connectors (you'll notice the resistance), press it firmly into the
backplane.
As
the card reaches its limit of travel, the free ends of the ex-
tractor levers will start to fold down against the card. Press on them until
the card is fully seated in the backplane.
To remove the card, grasp the free ends of the extractor levers, and pivot
them toward you (away from the card cage). This will force the card out
slightly from the connectors at the backplane. Continue pulling, but be
careful to pull both levers evenly to avoid jamming the PCA or breaking
its components. Use the same caution against static build-up and dis-
charge discussed in the paragraph on unpacking the card while handling
the board once you have removed it.
Repair or replacement of other electronic components could invalidate
your warranty.
