PSU Module Fitting  

Procedure  

To remove a PSU module:  

1 Identify the PSU module to be removed and disconnect its mains power cord.  

If the MV-825-RTR is powered on, it should continue to operate using the second PSU  

module.  

2 Unscrew two PSU securing screws, see Figure 11-3.  

3 Carefully pull the PSU module out of the MV-825-RTR chassis, using the PSU handle, see  

Figure 11-2.  

PSU Module Fitting  

IMPORTANT:   

Fitting of PSUs should only be attempted by trained personnel.  

A pozidriv screwdriver is required.  

Procedure  

To fit a PSU module:  

1 Note the orientation of a PSU module in the MV-825-RTR chassis, see Figure 11-3.  

2 Carefully insert the PSU module into the empty PSU module slot at the chassis rear.  

When the module is nearly fully pushed in, an increased resistance is met as the  

module’s DC connector engages with the chassis.  

The module should be finally fully pushed in.  

3 Tighten the two PSU securing screws, see Figure 11-3.  

Do not over-tighten the screws.  

4 Connect a power cord and switch the mains supply on.  

The module starts up and the PSU status LED should be lit green.  

The MV-825-RTR operation should be uninterrupted.  

The status LED is described in AC Mains Inlets, on page 25.
