the appropriate positions on the bottom of the MS8000.
Installation Procedure
Step1 Move the MS8000 in front of the workbench.
Step2 Lift the MS8000 a little higher than the workbench and place it on the workbench.
To ensure effective heat dissipation, keep at least a clearance of 10 cm (3.94 in.) around the MS8000.
Installing the Cables
Cabling Requirements
The principle of cabling is that service cables (such as network cable) should be separated from the
power cables. You can bundle the long cables with cable ties, and stick a label to a cable for indication.
Page 14
2-5
If your MS8000 is installed in a 19-inch rack, you can lay the cables either over the top or below the
bottom of the rack according to the actual situation (whether the signal cables of the equipment room
are wired on the rack top or below the rack bottom).
z Do not bundle cables near the heat dissipation hole to avoid speedy aging of cables.
z Fix the cables near the MS8000 and keep the cables loose between the interfaces and the fasten
points.
Connecting the Ground Wire
To ensure human and equipment safety against lightning and interference, the MS8000 must be
grounded reliably.
Step1 As shown in
Figure 2-5, connect one end of the ground wire to the grounding screw of the MS8000.
Figure 2-5 Connect the ground wire
(1)(1)
(1) Ground wire
Step2 Connect the other end of the ground wire to a ground point.
Generally, a rack has a set of ground bars, where you can connect the ground wire. In practice, you may
connect the ground wire properly according to the conditions.
Page 15
2-6
Connecting the AC Power Cable
The MS8000 ships with a cable retention clip. Before connecting the power cable, install the cable
retention clip first.
Step1 Ensure that the power switch of the MS8000 is off, and the power cable retention clip has been inst alled
on the MS8000 correctly.
Step2 Connect one end of the power cable to the power interface on the MS8000 rear panel, use the
cable-retention clip to fasten the power cable, and connect the other end of the power ca ble to a power
socket.
Figure 2-6 Connect the power cable
You are recommended to connect the power cable to a single-phase three-wire power socket. You
need to make sure that the neutral point of the power socket is properly grounded. Generally, the
neutral points in buildings are already grounded in construction.
Connecting the Console Cable and Network Cable
You can connect the console cable as per your requirements.
As shown in
Figure 2-7, connect the console cable and network cable. As for the other end of the
network cable, you can connect it according to the actual condition on the installation site, and the
connection is omitted here.
