2 RJ-45 connectors—One side (neither side is
better than the other for this purpose)
connects to the product (AP, SM, AC
Adapter, or cluster management module).
The other connects to the drop cable.
3 Ground post and washer—use heavy gauge
(10 AWG or 6 mm
2
) copper wire for
connection. Refer to local electrical codes
for exact specifications.
4 Ground Cable Opening—route the 10 AWG
(6 mm
2
) ground cable through this opening.
5 CAT-5 Cable Knockouts—route the two
CAT-5 cables through these openings, or
alternatively through the Conduit Knockouts.
6 Conduit Knockouts—on the back of the case,
near the bottom. Available for installations
where cable is routed through building
conduit.
The mounting procedure for the Surge Suppressor for PMP/PTP 450 Series is as follows:
1
Remove the cover of the 600SSH Surge Suppressor.
2
With the cable openings facing downward, mount the 600SSH to the
outside
of the subscriber
premises, as close to the point where the Ethernet cable penetrates the residence or building as
possible, and as close to the grounding system (Protective Earth) as possible.
3
Wrap an AWG 10 (or 6mm
2
) copper wire around the Ground post of the 600SSH.
4
Tighten the Ground post locking nut in the 600SSH onto the copper wire.
5
Securely connect the copper wire to the grounding system (Protective Earth) according to
applicable regulations.
6
Using diagonal cutters or long nose pliers, remove the knockouts that cover the cable openings to
the 600SSH.
7
Pack both surge suppressor Ethernet jacks with dielectric grease.
8
Wrap a splice loop in the loose end of the Ethernet cable from the SM.
9
Connect that cable to one of the Ethernet jacks.
Note
The 600SSH surge suppressor is shipped in the “isolated” position (pin 4 isolated by
68V from protective earth). If packet error issues occur over the Ethernet link (verify
by pinging the device through the 600SSH), configure the 600SSH to “grounded”
position (by moving the 600SSH switch from “isolated” to “ground”) to avoid ground
loops that may be present in the system.
