Installing an HXU-358 Multiplexer Card
HXU-358 multiplexer cards are installed in the front of the Wideband 3190
or ACE chassis.
1
Unscrew the two hold-down lugs on each side of the chassis front cover.
The cover folds down.
2
Connect your ESD wrist strap to the ESD strap input above the HiGain
Management Unit (HMU) slot or above multiplexer slot A in the ACE.
An ESD touchplate is integrated on top of the card’s front panel for
added anti-static protection.
3
Align the edges of the replacement card with the slot guides in the
multiplexer tray.
4
Grasping the card eject tabs, gently push the card into the bay.
5
Firmly press in on the tabs until the card snaps into place.
If you are installing an HXU-358 in a Wideband 3190 that has
a legacy multiplexer (HXU-357), contact Customer Service. A
mixed system is not allowed.
