Routine Maintenance
The NV5128 requires very little in the way of routine or preventative maintenance. Other than
cleaning the fan air intake filter, all that is required is periodic inspection of the system to make sure
no failures have occurred.
You might want to examine the system’s Indicator LEDs occasionally to ensure that the system is
operating normally and to make sure that air flow to the power supply fans is unobstructed.
Periodic Inspection
Periodically inspecting the NV5128 for signs of trouble is the best way to prevent unplanned out-
ages. The following items will be helpful when performing this inspection.
Begin the inspection at the front of the frame. Open the door to the router and make these observa-
tions.
1 Check the +48VDC LEDs on the front of the PS6000 power supplies. An LED that is off or
very dim in brightness indicates a failed or failing supply.
2 Place your hand lightly across the air intakes on the front of the power supplies. Slight air
movement should be felt, indicating that the internal cooling fans are running. These fans run at
very low speed, so only slight air movement will be noticed. A flashlight may be used to verify
that the fan blades are rotating at the proper speed.
3 Look at each active card and verify that none of the red alarm LEDs are illuminated. Normally,
the green and/or amber LED's should be illuminated. Refer to Indicator LEDs on page 76 to
interpret the LED status indicators.
Caution Only qualified service personnel should perform procedures in this section.
