Keep the cable from the NT to HiPath 3550 or HiPath 3500 as short as possible to ensure prop-
er operation.
Caution
7
There should be absolutely no ground connection between the HiPath 3550 wall
housing and the NT. Do not connect the shield of the connection cable you are using
either on the HiPath 3550 side or on the NT side.
If the HiPath 3550 system is separately grounded (such as with the 19-inch housing
of the HiPath 3500), you may make a connection between HiPath 3550 and NT.
