Installation Guide |
6.1 Information About the Installation
This section describes the information to be learnt before RHUB installation, including the RHUB installation scenarios, clearance, and installation environment.
6.1.1 Installation Scenarios
An RHUB can be installed in a 19-inch cabinet, rack, shelf, or on a wall.
NOTICE
To prevent the RHUB from water drops, the RHUB panel must not face upwards (shown in Figure 6-1) in any installation scenarios.
Figure 6-1 Improper installation mode
The RHUB mounting ears are installed in standard mode or reverse mode. The reverse mode is used by default. The two installation modes are defined as follows:
•In standard mode, the front of the mounting ear is aligned with the RHUB panel, as shown in Figure 6-2.

•In reverse mode, the front of the mounting ear is 31 mm away from the RHUB panel, as shown in Figure 6-3.
Figure 6-3 Installing mounting ears in reverse mode
Installing an RHUB in a 19-Inch Cabinet or Rack
Installing an RHUB in a 19-inch cabinet or rack: Secure the mounting ear to the mounting bracket by using M6 screws.
•If there are no other modules installed in the 1 U space near the RHUB, install the RHUB directly. Otherwise, remove the modules before installing the RHUB.
•Before installation, you need to check the installation mode supported by the rack and adjust the position of the mounting ear.
Figure 6-4 and Figure 6-5 show RHUBs installed in a cabinet or rack, respectively.
