5.3.2 Multi-Device Deployment Scenario
Note
When multiple VCN520s or VCN540s are deployed, a guide rail needs to be installed for each device.
A VCN520 or VCN540 requires 2 U space. A guide rail requires 1 U space. Therefore, installing a
single device requires a total of 3 U space. Before installing devices, properly plan the cabinet space.
For details about how to install a device in the cabinet, see the single-device deployment scenario.
This section introduces how to install multiple devices in the cabinet.
If multiple VCN520s or VCN540s are installed, a guide rail needs to be installed for each device, as
shown in the following figure.
