HXU-359 List 1
HXU-359 multiplexer cards can be installed in a Soneplex Wideband 3190 or
a standalone ACE enclosure.
1
For a Soneplex Wideband 3190, 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 on the chassis
(above the HMU slot on the Soneplex Wideband 3190).
3
Set switches 3 and 5 on the SW2 switch block located on the circuit
board, behind the front panel.
•
For an HMU-managed Soneplex Wideband 3190, set switches 3 and
5 to the Off position (default settings).
•
For a standalone ACE enclosure or to enable the HXU craft port, set
switches 3 and 5 to the On position.
4
Align the edges of the card with the slot guides in the multiplexer tray.
5
Grasping the card eject tabs, gently push the card into the bay.
6
Firmly press in on the tabs until the card snaps into place.The LEDs flash
momentarily. The Power LED and Active LED on the active multiplexer
remain illuminated. The LEDs on the inactive (standby) multiplexer
should be off, except for the Power LED.
If you are installing an HXU-359 in a Soneplex Wideband 3190
that has a different multiplexer model, contact Customer
Service. Do not mix multiplexers in a system.
When installed in a working system that already has an
HXU-359, the second HXU is automatically configured for that
system by the active HXU in the shelf.
