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.
