Installing a data line protector
It is recommended that you use a data line protector to connect the OSU to the user’s LAN
or computer. The data line protector provides protection against static electricity and
momentary lightning surges on the OSU cable and the subscriber’s LAN, to the OSU, the
user’s computer, and other devices that may be connected to the local Ethernet LAN.
The recommended data line protector can be ordered from NextNet Wireless, using the part
number 585-9000-3414.
Figure 9 illustrates how the cables are connected through the data line protector and into the
power supply cord.
Note: So that the data line protector can provide protection to the OSU and user’s
LAN-connected equipment, the furnished ground cable must be connected to a good earth
ground or equivalent as required in article 250 of the National Electric Code. Failure to
provide correct grounding to the data line protector could result in damage to the user’s
computer or LAN-connected equipment.
