24 EX7000 Series Basic Operation
Installation is in the reverse order. Carefully insert the multi-pin white plastic connector, at the end
of the switch module cable, into the mating cable extending from the EX72SF enclosure opening.
Press the two plastic connectors firmly together until you can feel slight clicking action as the
release tab on the enclosure side connector drops into place, locking the two connectors together.
Next, align the sides of the carrier with the dark plastic card guides on each side of the rectangular
opening. Slide the switch and carrier all the way in until it reaches the rear stop which should
place the front body of the connector approximately flush with the front panel of the enclosure.
Place the faceplate back in position and secure with the two pan head Philips screws.
To remove a SP4T or SP6T switches from the enclosure, simply remove the four flat head Philips
screws from each corner of the switch. Slide the switch forward until it is away from the enclosure
and far enough out to access the 16 pin ribbon cable connector plugged into the rear of the switch.
Pull the release tab on the rear of the switch away from the connector and pull the ribbon cable
connector out of the switch.
Installation is in the reverse order. Carefully insert the ribbon cable connector into the mating
connector on the switch module. Align the ribbon cable connector tab with the release tab on the
switch’s connector. Press the ribbon cable connector firmly in until the release tab on the switch
clicks into place locking the connector in place. Slide the switch all the way in until it the
mounting flange is flush with the front panel of the enclosure. The switch can operate in any
orientation but the standard configuration is for the #1 port to be closest to the right side of the
enclosure which puts port 5 and 6 at the top. Align the four holes and secure with the four flat
head Philips head screws.
Following the mechanical installation, the EX72SF needs to have its Configuration file updated.
This will not be necessary for cases where a switch is simply replaced with another of the same
model. The Configuration file tells the internal control and drive circuitry exactly what is
connected to each port of the unit. Updating the Configuration file is accomplished by running the
Configurator software tool and following the intuitive prompts. Consult the Configurator User’s
manual for details. Alternatively, the new Configuration file can be generated by the factory and
downloaded over the Internet. Consult the factory for details.
EX7400
Generally speaking, most EX7400 models will have their switches mounted internally and are not
intended for easy field upgrades or repairs. Please contact the VTI Microwave in the event of a
failure.
