Rack Mount 1000 Mbps GigE Ethernet Surge Protector

Gas Discharge Tube design to be used with the popular   PRM4 and PRM24 1RU Rack Mount Chassis made by APC.  We also sell a PRM4 4 slot rack that is Din Rail Mount.

This GigE-APC Ethernet Surge Protector-Suppressor-Arrestor is ideal for the NOC because of the small form factor. Both solid state surge components as well as a Gas Discharge Tube allow it to protect CAT5/6 circuits like no other

Proven Circuit

The proven and popular 444SS GDT/Avalanch Diode parallel hybrid design is what puts this circuit ahead of the others. (See ITU-T K.99)  This design uses a triple hybrid design that incorporates, reactive,  solid state and Gas Discharge Tube protection to clamp both fast and large impulses.

Where a number of GigE devices are colocated becomes an ideal application for this Ethernet Surge Protector as a result of the 1RU size. This unit supports POE 802.3af modes A and B. Shielded RJ45 jacks provide grounds and bonding to shielded plugs and shielded cables.

Shielded Connectors

This 1000 Mbps Ethernet Surge Protector-Suppressor-Arrestor is a direct cross for the APC PNET6TR; however, this unit but is much more robust because of the shielded RJ45 jacks for industrial grounding/bonding and less loading for the long GigE circuits and greater protection from surges.

The design of this circuit does not employ Metal Oxide Varistors (MOV)s nor Back Up Gaps (BUGs); therefore it is both fast, durable and reliable!

It is simply a better circuit. Greater protection for your expensive equipment is provided by the GigE-APC Ethernet Surge Protector.

As previously mentioned, shielded and grounded jacks bond shielded CAT5 and CAT6 wiring to the building ground system. There are also multi stage surge elements that are designed specifically for demanding NOC and WISP environments. This product was invented at the request of our WISP customers who had had failures of the PNETR6.

Outdoor Version Available

This is the rack mount version of the outdoor product 800-GIGE-SS-HV.

    Linked at gigabit speeds sans any issues. The card is compact and works well as I have had the unit for over 11 months now (I bought this unit in November’16). The real test came during a freak thunderstorm in the mid west (circa Feb’17) and I can attest that ubiquitous unit can withstand one. The price is right albeit the packaging could have been more glittery but then again everything that ‘glitters’ ain’t ‘gold’ right? Go for it!

    For better or worse, your surge arrestors saved me from blowing an
    entire cabinet during a direct lightning strike last night. The Netonix
    PoE power supply blew (as did a bunch of expensive stuff on the tower),
    but I think without the arrestors, I’d be in a lot more painful

    We either had a really bad power surge or a very close lightning strike at our NOC over the weekend. No visible signs of a direct strike to the tower. I’m leaning towards the power surge since other networked things in the office died, and our office telco/network closet is uplinked to the server room via a pair of fiber. Railroad stuff was all messed up at several crossings. And other businesses nearby lost various electronics as well.

    Two AF24’s and an AF5. GigE-APCs at the bottom weren’t burned up, but were obviously dead. The AF POE injectors all shut down when plugged into them. The GigE-SS’s on top apparently stopped the surge from hitting the radios. After I bypassed the GigE-APCs at the bottom, the ethernet links would only run at 100Mbps, plus errors. After bypassing the GigE-SS’s on top this morning, all three are running GigE again with no errors. So that saved a lot of work today.

    However, it wasn’t so good for the 5GHz 450i cluster at the top. Don’t know how, but one survived. We relied on the 450’s built-in suppression at the top. Didn’t happen. The GigE-APCs were all dead. So yeah, you should probably just run GigE-SS’s near a radio, even if it claims surge suppression is built in.

    The PacketFlux PowerInjector+Sync had two of the ports with visible damage on the board. Took out the SiteMonitor Base unit with it. Forrest, if you want these for failure analysis, just let me know. I’d be happy to send them to you. When I got the office, the green LED was flashing 2, and I believe port #2 was a damaged one. It also took out all four of those ports on the CCR1036.

    I’ve seen similar events over the years and this clearly looks like bottom up, i.e. utility surge. And of course the one thing I forgot after doing the generator and transfer switches…. the f’n whole panel surge suppressor. I would’ve moved the existing one over to the other panel, but I needed different breakers.

    Bottom line, use MTC surge suppressors top and bottom and your life will be better.*
