As for electric parameters, both places for power module installation are identical. In the context of
device operation, the power module located closer to the edge is considered as the main module, and the
one closer to the centre—as the redundant module. Power modules can be installed and removed without
powering the device off. When an additional power module is being installed or removed, the switch
continues operation without restart.
To install a power module:
Step 1. Install the power module into the pocket shown in Fig. 7.3 or Fig. 7.4.
Step 2. Screw the module to the case.
Step 3. Follow the instructions in Section 7.2 to power on.
To install the device:
Step 1. Assemble the device. In case of installation to a 19" form-factor rack, mount the support brackets
from the delivery package to the rack.
Step 2. Ground the case of the device. This should be done prior to connecting the device to power
supply. An insulated multiconductor wire should be used for earthing. The device grounding and the earthing
wire section should comply with the Electric Installation Code. The earth bonding point is located on the rear
panel, see Fig. 6.4, Fig. 6.5, Fig. 6.6.
Step 3. If a PC or another device is supposed to be connected to the switch console port, the device
should be also securely grounded.
Step 4. Connect the power cable to the device.
Step 5. Turn the device on and check the front panel LEDs to make sure the terminal is in normal
operating conditions.
