x900 Series Switch and SwitchBlade
Supply cable specifications:
■
three-core cable is required
■
minimum core size: 3.3mm
■
minimum cable rating: 600V, 90 degrees C
Warning Disconnect the power supply cable before starting this procedure.
1.
Remove the transparent protective terminal cover.
2.
Strip the supply cable wires to expose 7.5mm (0.31in.) of bare conductor.
Terminate the wire with a nylon insulated solderless ring tongue terminal,
JST FN5.5-5 or equivalent, using a crimp tool.
3.
Connect the ground wire to the ground terminal. Use the diagram on the
rear panel of the switch to identify terminals. Tighten the terminal to
between 2.4 and 4.0 Nm (21.3 and 35.4 lbf in).
Caution Check that the PSU terminals are wired to the correct polarity.
You will damage it if you incorrectly connect it.
4.
Connect the positive feed to the + (positive) terminal and the negative feed
to the - (negative) terminal. Tighten the terminals to between 2.4 and
4.0Nm (21.3 and 35.4 lbf in).
Note that the DC return input terminal must be connected as an Isolated
DC return (DC-I).
5.
Ensure there are no exposed cable strands.
6.
Replace the cover. You must replace the transparent plastic terminal cover
before continuing.
7.
Secure the supply cable to the rack framework or a similar object to ensure
that connections are isolated from any force applied to the cable.
8.
Ensure the circuit breaker is off for the supply circuit and the Run/Standby
control on the PSU. Release the Run/Standby control so that it is not
pushed in (which is the Off position).
9.
Connect the supply cable wires to the circuit breaker.
10. Turn on the PSU by pushing in the Run/Standby control.
11. Confirm that the switch is receiving power.
Check that at least one of the PSU LEDs on the front panel of the switch is
lit green. If no LEDs light, refer to the Hardware Reference for
troubleshooting information.
