Eliminating Static Electricity from Twisted Pair Cables (Grounding)
Under certain conditions, twisted pair cables can become charged with static electricity. Connecting a statically charged
twisted pair cable to the XG0448 can cause the device or its LAN port to operate falsely or to become damaged.
Use a static removal tool to discharge twisted pair cables to ground prior to connecting them to the XG0448.
Note that a discharged twisted pair cable that has been left unconnected for a long time may become statically charged
again.
Ensuring Security
If no password is set, any users on the network can configure this device. In that situation, you cannot ensure security
against unauthorized use. Therefore we strongly recommend that you set a password.
