switch. After you select an appropriate outlet, use the following procedure to apply AC power.
1. Connect the fem ale end of the supplied AC power adapter cable to the power receptacle on the back
of the switch.
2. Connect the 3-pronged end of the AC power adapter cable to a grounded 3-pronged AC outlet.
3. On the rear panel, move the ON/OFF switch to the ON position ( ).
When you apply power:
Ÿ All green PoE and Link/ACT LEDs blink momentarily.
Ÿ Th e fa n starts.
Ÿ The yellow Power LED goes ON.
Ÿ The Link/ACT LEDs for every port connected to a device flash, as the switch conducts a brief
Power On Self-Test (POST ).
After the switch passes the POST, the Link/ACT LEDs for every port connected to a device go ON.
The PoE LEDs also go ON if Power Devices are connected. The switch is now functional and ready to
pass data.
If you do not hear the fan, or if the Power LED is not ON, check that the power cable is plugged in
correctly, the ON/OFF switch is set to the ON position, and that the power sour ce i s good and not
controlled by a wall switch. If this does not resol ve th e pr oblem, see Chapter 5, Troubl eshooting.

Jumbo Frames
The switch provides efficient large sequential data transfer s by supporting jumbo frames up
to 9000 bytes. Compared to stan dard Ether net fra mes that ru n up to 1500 by tes, using j umbo
frames significantly reduces the per-packet over head required to process pr otocol
encapsulation fields, reduce processing time , and increase transfer performanc e.
By default, jumbo frames are enabled on the switch. To u se jumbo frames, both the source
and destination end nodes (such as a computer or ser ver) must support jumbo frames. In
addition, when the connecti on o per ates at full-dupl ex, all swit che s in the network b etween t he
two end nodes must be able to accept th e extended frame size. For half-duplex c onnections,
all devices in the collision domain must support jumbo frames.
To disable jumbo fra mes, uncheck Enable Jumbo Frames.
Power Saving Mode
By default, the switch is configured for full power saving mode. This mode automatically
adjusts the power provided to ports. The foll owing power saving mode selections are
available:
Choices are:
Ÿ Full = activate maximum power saving mode. This is the default setting.
Ÿ Link-up = save power when the switch port link is up (operational).
Ÿ Link-down = save power when the switch port link is dow n (non-operational).
Ÿ Disable = deactivate power saving mode.

Additi onal Troubleshooting Suggestions
If the suggestions in Table 5-1 do not resolve your problem, refer to the troubleshooting
suggestions in this secti on.
Network Adapter Cards
Be sure the network adapter cards installed in the PC used to config ure the switch are in
working condition and the latest software dri ver has been in stalled.
Configuration
If problems occur after altering the switch’s network configuration, restore the original
connections and determine the pro blem by i mplementing the new c hang es one step at a time.
Be sure cable distances, repeater limits, and other phy sical aspects of the installation do not
exceed the Ethernet limitations.
Switch Integrity
If required, verify the integrity of the switch by resetting it. To reset the switch, use the reset
button on the front panel (see “Reset Button” on page 12) or use the Maintenance > Warm
Restart page on the switch’s Web managem ent interfa ce (see “Warm Restart Page” on page
60). If the problem continues, contact EtherWAN Sy ste ms technical support.
Auto-Negotiation
The 10/100 Mbps ports negoti ate the correct duplex mode and speed if the switch is
configured for auto-neg otia tion (t his is the swit ch’s def aul t setting) and t he device at the other
end of the link supports auto-negotiation. If the device does not support auto-negotiation, the
switch determines only the spe ed correctly and the duplex mode default s to half-duplex.
