to act as a backup for several others. A salvo within the control system could then route the appro-

Maintenance
The frame requires very little in the way of routine or preventative maintenance. Other than clean-
ing the fan air intake filter, all that is required is periodic inspection of the system to make sure no
failures have occurred.
Miranda master control panels require no maintenance.
Periodic Inspection
Periodically inspecting the frame for signs of trouble is the best way to prevent unplanned outages.
The following items will be helpful when performing this inspection. Begin the inspection at the
front of the frame. Open the door to the frame and make these observations.
1 Check the +48VDC LEDs on the front of the PS6100 power supplies. An LED that is off or
very dim indicates a failed or failing supply.
2 Place your hand lightly across the air intakes on the front of the power supplies. You should feel
slight air movement, indicating that the internal cooling fans are running. These fans run at very
low speed, so you will notice only slight air movement. You can use a flashlight to verify that
the fan blades are rotating at the proper speed.
3 Look at each input/output module and verify that none of the red alarm LEDs are illuminated.
Normally, the green and/or amber LEDs are illuminated. Refer to Table C-8 on page 208 to
interpret the LED status indicators.
