Power Cord Set Requirements
The wide-range input feature of the VH-4802 Ethernet switch permits it to
operate from any line voltage between 100 and 240 VAC.
The power cord set (appliance coupler, flexible cord, and wall plug) you
received with the switch meets the requirements for use in the country
where you purchased the switch.
Power cord sets for use in other countries must meet the requirements of
the country where you use the switch. For more information on power
cord set requirements, contact your Enterasys Networks Support
Representative.

and a maximum of 6.56 feet (2.0 m).
• All power cord sets must be approved by an acceptable accredited
agency responsible for evaluation in the country where the power
cord set will be used.
• The power cord set must have a minimum current capacity of 10A
and a nominal voltage rating of 125 or 250 VAC, as required by each
