Appendix C. MAINTENANCE
C.1 Overview
Figure C-1. Comtech EF Data LPOD Outdoor Amplifiers / BUCs
The fans used by Comtech EF Data's LPOD family of Outdoor Amplifiers / Block
Up Converters (BUCs) (Figure C-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. This
appendix outlines the procedures for uninstalling the LPOD PD 1, PS 1.5, or PS 2
fan shroud, inspecting and cleaning the heat sinks, and then re-installing the fan
shroud.
You can use the temperature trending data, available from the LPOD HTTP
Interface 'Status | Trending Graphs' page (Figure C-2 ) as a guide to determine if
more or less frequent preventative maintenance is required.
