5.1 Information About the Installation
This section describes the information to be learnt before RHUB3908 installation, including the
RHUB3908 installation scenarios, clearance, and installation environment.
5.1.1 RHUB3908 Installation Scenarios
An RHUB3908 can be installed in a 19-inch cabinet, rack, shelf, or on a wall.
The RHUB3908 supports that 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:
lIn standard mode, the front of the mounting ear is aligned with the RHUB3908 panel, as
shown in Figure 5-1.
Figure 5-1 Installing mounting ears in standard mode
lIn reverse mode, the front of the mounting ear is 31 mm away from the RHUB3908 panel,
as shown in Figure 5-2.

Installing an RHUB3908 in a 19-Inch Cabinet or Rack
Installing an RHUB3908 in a 19-inch cabinet or rack: Secure the mounting ear to the mounting
bracket by using M6 screws.
lIf there is no other modules installed in the 1 U space near the RHUB3908, install the
RHUB3908 directly. Otherwise, remove the modules before installing the RHUB3908.
lBefore installation, you need to check the installation mode supported by the rack and adjust
the position of the mounting ear.
Figure 5-3 and Figure 5-4 show RHUB3908s installed in a cabinet or rack, respectively.

Installing an RHUB3908 in a 19-Inch Shelf
When an RHUB3908 is installed in a 19-inch shelf, the shelf must be installed on a wall. One
shelf can house multiple RHUB3908s with 1 U space between two RHUB3908s.
