ACTIVITY
Mounting a USB HUB4 MAAP to a mounting bracket
Rack ounting the USB HUB
You can mount the HUB4 to an optional rack shelf or directly onto a rack using
an Extron rack space frame, such as the CPM112R (for the MAAP model) or the
AAP 301/302 (for the AAP model). See “Optional accessories” in appendix A,
“Reference information”, for a list of rack shelves and rack space frames that can be
used with the two USB HUB4 models.
UL guidelines for rack ounting
The following Underwriters Laboratories (UL) guidelines pertain to the installation
of the USB HUB4 onto the front of a rack:
• Elevated operating ambient temperature — If the equipment is installed in
a closed or multi-unit rack assembly, the operating ambient temperature of
the rack environment may be greater than room ambient. Therefore, consider
installing the equipment in an environment compatible with the maximum
ambient temperature (Tma) specified by the manufacturer.
• Reduced air ow — Install the equipment in the rack so that the amount of
air ow required for safe operation of the equipment is not compromised.
• Mechanical loading — Mount the equipment in the rack so that uneven
mechanical loading does not create a hazardous condition.
• Circuit overloading — When connecting the equipment to the supply
circuit, consider the connection of the equipment to the supply circuit and
the effect that circuit overloading might have on overcurrent protection and
supply wiring. Consider equipment nameplate ratings when addressing this
concern.
• Reliable earthing (grounding) — Maintain reliable grounding of rack-
mounted equipment. Pay particular attention to supply connections other
than direct connections to the branch circuit (such as the use of power strips).
