Federal Communication Commission Interference Statement
This equipment has been tested and found to comply with the limits for a
Class B digital device, pursuant to Part 15 of the FCC Rules. These limits are
designed to provide reasonable protection against harmful interference
in a residential installation.
This equipment generates, uses and can radiate radio frequency energy
and, if not installed and used in accordance with the instructions, may
cause harmful interference to radio communications. However, there is no
guarantee that interference will not occur in a particular installation.
If this equipment does cause harmful interference to radio or television
reception, which can be determined by turning the equipment off and
on, the user is encouraged to try to correct the interference by one or
more of the following measures:
- Reorient or relocate the receiving antenna.
- Increase the separation between the equipment and receiver.
- Connect the equipment into an outlet on a circuit different from that
to which the receiver is connected.
- Consult the dealer or an experienced radio/TV technician for help.
This device complies with Part 15 of the FCC Rules. Operation is subject to
the following two conditions: (1) This device may not cause harmful
interference, and (2) this device must accept any interference received,
including interference that may cause undesired operation.

Power saving (***)
* This unit automatically detects and adjust for straight or crossover
Ethernet cables, so either type of cable may be used.
** Site-terminated Ethernet cables are not recommended. Always use
preassembled cables.
*** This function automatically recognizes the port link status and the
length of Ethernet cables, then adjusts the operating power accordingly.
This also adjusts the power when the data is not transmitted (the device
connected to this switch should be compatible with IEEE802.3az EEE).
