6 INSTALLATION

Remove power to the shelf by turning off the power supply or unplugging the power supply connected to the PatchSwitch chassis.

6.1Interlock Jumper Installation

If an interlock option is desired for the system, the proper jumper must be connected in each A/B Switch Module before installation in the chassis. Each A/B switch module has five interlock positions. One jumper position for each of four interlock groups labeled 1 through 4 and one vertical interlock group labeled V. See Figure 4-7for the location of the jumpers on the module.

Interlocking is used to protect the user from accidentally switching a common backup piece of equipment onto two or more different data lines. This is accomplished by allowing only the first module in that group to switch. The remaining modules remain in the “normal state” or the “A” position. Modules in the “B” position once switched to “A” will remain in the “A” position.
