Reset Button

The reset button, accessible through a hole in the rear panel of the EX7000, implemented according to the LXI LAN Configuration Initialize (LCI) Mechanism specification, can be used to restore default network settings. This is useful for recovery from an incorrect or unknown network configuration. To perform a network reset:

1)Press and hold the reset button.

2)Continue to hold the reset until the LAN LED flashes (approximately 5 s).

3)Release the reset button.

The EX7000 will now revert back to the default network configuration (DHCP and AutoIP enabled) instead of its previous settings. VXI-11 Discovery (supported by the VISA IO-Libraries) can be used to determine the IP address of the instrument.

FRONT PANEL VIEW

 

The front panel of each EX7000 model is different. The EX71HD front panel is configured with

 

 

twelve identical mounting locations for miniature microwave switch modules. The EX72SF front

 

 

panel is configured with twelve locations for latching microwave switches. The twelve locations

 

 

are divided into six locations for SPDT switches and six locations for SPnT and/or transfer

 

 

switches. The EX7400 will be configured to satisfy its unique customer specified requirements.

 

 

Details for each EX7400 are supplied as supplements to this manual and are generally printed on

 

 

yellow paper.

 

 

EX71HD

 

 

The EX71HD enclosure, shown in Figure 1-1, and switch modules are fitted with blind mating

 

 

connectors to simplify switch module removal and installation. The mounting plate on the

 

 

switches contains two rear facing alignment pins that fit into holes on the front panel. These pins

 

 

only allow full insertion of the switch into the EX71HD enclosure opening when properly aligned.

 

 

 

 

NOTE

Before proceeding with the removal and/or installation of any microwave switch modules in any

 

 

of the EX7000 Series assemblies, turn the ac power switch to the OFF position and remove the ac

 

 

power cord.

 

 

To remove a switch from the enclosure, simply remove the four miniature hex head cap screws

 

 

from the four corners of the switch using a 5/64” hex key wrench and pull the switch forward.

 

 

There will be some slight resistance until the blind mate connectors disengage.

 

 

Installation is in the reverse order. Carefully insert the multi-pin connector end of the switch into

 

 

the opening, turning the switch module to arrange the two alignment pins to be on the top side of

 

 

the switch. Insert straight back until the blind mating connector alignment pins engage. Once these

 

 

alignment pins are engaged, press firmly until the switch slides in flush with the EX71HD front

 

 

panel. Insert and tighten the four 2-56 hex head cap screws.

 

 

Following the mechanical installation, the EX72HD 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.
