Device rack installation
To install the device to the rack:
1. Attach the device to the vertical guides of the rack.
2. Align mounting holes in the support bracket with the corresponding holes in the rack guides. Use the holes
of the same level on both sides of the guides to ensure the device horizontal installation.
3. Use a screwdriver to mount the device to the rack.
4. To dismount the device, disconnect cables and remove support bracket screws from the rack. Remove the
device from the rack.

Power module installation
Device can operate with one or two power modules. The second power module installation is necessary when
the device operates under strict reliability requirements.
From the electric point of view, 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 inserted and removed without powering
the device off. When additional power module is inserted or removed, the device continues operation without
reboot.
