APC 600 & Extra Surge Protection Gigabit & Coax when have just Phone
This was originally posted on APC forums on 8/18/2010
Ok, I have a APC 600 without the protection that I need, so I'll have to add a surge protection strip to the unit to get the coax & the Gigabit protection that I need.
Which is better?
Surge Protector plugged into the wall with the APC 600 plugged into it or APC 600 plugged into the wall?
Having studied surge protection for years during major lightning storms, I know the best methods for protection except for which goes first to the wall. (laughs)
For those with cable modems, you need a coax protector, 2 Gigabit protectors.
--Coax From Wall Into Protector
Gigabit Protectioned to Unprotected (#1)
Gigabit Unprotected to Protected (#2)
Having equipment hit with major lightning strikes many times over the last 25+ years, I know how unknown how a lightning strike will travel.
The above method protects the Coax Modem and the Computer.
If you leave off #1, then any extra juice from the computer that travels within the network adaptor even when protected. I've seen it happen.
If you leave off #1 & #2. Rarely (Once), I saw the network port blown.
HEAVY Lightning does Damage in unpredictable ways.
If you don't protect the Gigabit Switch/Hub and you protect ANY computer plugged into the Network, then You can more than likely blow the switch/hub and it will travel down the network cables to ANY unprotected computer.
Also for those of you who might forget, At least at the begining of Lightning season, Go outside and Double check the routing of your ground cable from the Power Box, The Telephone Box, The Cable Box, to make certain that it's still connected to the ground rod that is buried in the ground. Pull on it.
In several cases, I've found where it had either been hit with a lawn mower occassionally, Corrosion happened, etc. Without that ground cable, it lightning blows right on through ANY protector that the Utility company provides. Most of the time, I've found houses with damage where this was the case.
