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, particularly in installations of the OSU above the roof line. 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 Motorola, using the part number
585-9000-3414.
Figure 7 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.
