6.1.1 Installation Scenarios

An RHUB can be installed in a 19-inch cabinet, rack, shelf, or on a wall.

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.

Installing an RHUB in a 19-Inch Shelf

When an RHUB is installed in a 19-inch shelf, the shelf must be installed on a wall. One shelf can house multiple RHUBs with 1 U space between two RHUBs.

Figure 6-6 and Figure 6-7 show RHUBs installed in a 19-inch shelf.

Installing an RHUB on a Wall

An RHUB can be installed on a wall.

The wall on which an RHUB is installed must meet the following requirements:



When a single RHUB is installed, the wall must have a capacity of bearing at least four times the weight of the RHUB.



Expansion bolts must be tightened to 10 N·m (88.507 bf·in.) to ensure the bolts work properly and the wall remains intact without cracks in it.

Figure 6-8 shows an RHUB installed on a wall.

6.1.2 Installation Clearance Requirements

When an RHUB is installed in a 19-inch cabinet, rack, shelf, or on a wall, a minimum clearance is required for easy cabling and operation and maintenance. A recommended installation clearance is provided based on experience.



Do not install or place inflammable materials above or under an RHUB.



A clearance of 350 mm must be reserved in front of the air intake vent of the fan of the power supply unit (PSU) for maintenance.

Figure 6-9 shows the installation clearance for the RHUB installed in a 19-inch cabinet, rack, or shelf.
