MAINTENANCE

Maintenance requirements for the Redundant Amplifier switch are minimal, consisting merely
of periodic cleaning.

5.1 Preventive Maintenance

The outside of the Redundant Amplifier switch should be cleaned during routine headend
equipment maintenance.

5.2 Fuse Replacement

Caution

: 

For continued safe operation and to reduce the risk of fire, replace fuses with the

same type and rating

.
