RF-8000E Operations Manual
Chapter 6. Maintenance and Troubleshooting — 65
Keeping Spares
Because repeaters are often used to provide critical coverage, customers are advised to follow a
sparing policy. While most telecommunications carriers or system operators have internal policies
relative to equipment sparing, in the event that one does not exist, Peninsula Engineering Solutions
recommends maintaining a minimum of one (1) spare unit for every increment of 10 units or fraction
thereof. This assumes that all spares are immediately available to the technician in need for
installation.
When travel time to a site is long or access is difficult (helicopter, hike or horse), then, more spares
located close to or at the repeater site are recommended. Frequently, organizations will store an
amplifier inside an RF repeater, thus, placing the spare exactly where needed. Amplifiers stored in
sealed, anti-static packaging is recommended for on-site spare inventory.
Each organization should develop a company-specific, equipment-specific policy that meets their
needs, taking into account geographic considerations, and the quantity of repeaters used in the
network.
