NOTE
The optional DC power cable is required when two systems of electrical power
equipment are used.
To add a second power supply system, remove the protective cap from DC power
connector 2 and attach the DC power cable. Store the removed cap securely.
NOTE
By adding a second power supply unit, a redundant supply of DC power can be
provided to the Switch.
However, in such cases, shut off the electrical power equipment before attaching
the redundant power cable.
(2) Removing
[Step 1]
Disconnect the DC power cable from the DC power connector on the back face of the
device. Push the tabs on the both sides and pull it out.
[Step 2]
Detach the ground cable from the device.
Prior to attaching or detaching the power cable, shut off your electrical power
equipment. Otherwise, a fire or an electric shock might result.
NOTE
By adding a second power supply unit, a redundant supply of DC power can be
provided to the Switch.
However, in such cases, shut off the electrical power equipment before detaching
the redundant power cable.
4.5.5 DC power cable (redundant power models (AX3630S, AX3640S))
Be sure to use a DC power cable specified by ALAXALA Networks Corporation.
Otherwise, a fire or an electric shock might result.
A trained engineer or maintenance staff should attach and detach the DC power
cable.
The terminals of DC power cable are to be connected. Wrong handling of the DC
power cable can cause a fire or an electric shock.
Prior to attaching or detaching the DC power cable, shut off your electrical power
equipment. Otherwise, a fire or an electric shock might result.
NOTE
For required specifications of power cables, see 2.3.4 Electrical power equipment
for −48 V DC (redundant power models (AX3630S and AX3640S)).
