complete the connections in any order. Refer to “Network Wiring” on page 9 when
making network connections.
NOTE: To prevent overheating, do not operate this product in an area that exceeds
the environmental temperature range listed in the table of specifications.
Consideration must be given if installed in a closed or multi-unit rack assembly since
the operating ambient temperature of the rack environment may be greater than the
room ambient. Contact with thermal insulating materials should be avoided on all
sides of the unit.
NOTE: The maximum continuous current from equipment under any external load
conditions shall not exceed a current limit that is suitable for the minimum wire
gauge used in interconnecting cables. The ratings on the connecting unit's supply
input should be considered to prevent overloading the wiring.
