PMP 320 Hardware Installation Surge Suppression Information
Surge Suppression Information
The AP has metal - to - metal contact from the tower or support structure, through the antenna,
through the coax cable, to the radio . Installing surge suppression at the AP is strongly
recommended to provide the best protection from lightning strikes.
Up to four 600S SD surge suppressors can be mounted in series on an Ethernet link without
degrading the link. The equivalent of a 600S SD is built into each of the 8 ports on a CMM4 and
counts as one of the four .
As an example, a typical installation might have properly - grounded 600S SD units within 3 ft (1
m) of each AP and additional properly - grounded 600S SD units on each Ethernet cable mounted
outside
at the point of cable entry to a telecommunications hut that contains the CMM4.
