This appendix outlines the procedures for uninstalling the LPOD-R PS .5, PS 1, or
PS 1.5 fan shroud, inspecting and cleaning the heat sinks, and then re-installing
the fan shroud.
Figure B-1. Comtech EF Data LPOD-R Outdoor Amplifiers / BUCs
The fans used by Comtech EF Data's LPOD-R family of Outdoor Amplifiers / Block
Up Converters (BUCs) (Figure B-1) are designed for long life, even in harsh
environments. Still, they are mechanical devices, subject to wear, and may need
replacement after several years.
In most environments, Comtech EF Data recommends clearing the heat sinks of
dust and debris approximately once per year to ensure optimal fan life. You can
use the temperature trending data, available from the LPOD-R HTTP Interface
'Status | Trending Graphs' page (Figure B-2 ) as a guide to determine if more or
less frequent preventative maintenance is required.
