CHAPTER 5 Cabling the Device
MP-1288 | Hardware Installation Manual
6.
Connect the other end of the grounding wire to the building protective earth. This should
be in accordance with the regulations enforced in the country in which the device is
installed.
Connecting Ethernet Interfaces
The device provides two 100/1000Base-T Gigabit Ethernet ports (RJ-45) for connecting to the IP
network (e.g., LAN). The ports support half- and full-duplex modes, auto-negotiation, and
straight or crossover cable detection.
The ports can operate as a pair (Ethernet Group) to provide 1+1 port redundancy, where one
port serves as the active port while the other as standby. When the active port fails, the device
switches to the standby port.
The cabling specifications and procedure for connecting the device to the LAN is as follows:
■
Cable: Straight-through, Category (Cat) 5/5e/6 cable
■
Connector: Standard RJ-45
