switch. After you select an appropriate outlet, use the following procedure to apply AC power.
1. Connect the female 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:
All green PoE and Link/ACT LEDs blink momentarily.
The fan starts.
The yellow Power LED goes ON.
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 source is good and not
controlled by a wall switch. If this does not resolve the problem, see Chapter 5, Troubleshooting.

Port Configuration Page
Path: Configuration > Ports
The Port Configuration page lets you enable jumbo frames, configure power saving mode,
and view the switch port status and configure port modes.
33
EX17908 Web-Smart Switch User Guide
Jumbo Frames
Power Saving Mode
The switch provides efficient large sequential data transfers by supporting jumbo frames up
to 9000 bytes. Compared to standard Ethernet frames that run up to 1500 bytes, using jumbo
frames significantly reduces the per-packet overhead required to process protocol
encapsulation fields, reduce processing time, and increase transfer performance.
By default, jumbo frames are enabled on the switch. To use jumbo frames, both the source
and destination end nodes (such as a computer or server) must support jumbo frames. In
addition, when the connection operates at full-duplex, all switches in the network between the
two end nodes must be able to accept the extended frame size. For half-duplex connections,
all devices in the collision domain must support jumbo frames.
To disable jumbo frames, uncheck Enable Jumbo Frames.
By default, the switch is configured for full power saving mode. This mode automatically
adjusts the power provided to ports. The following power saving mode selections are
available:
Choices are:
Full = activate maximum power saving mode. This is the default setting.
Link-up = save power when the switch port link is up (operational).
Link-down = save power when the switch port link is down (non-operational).
Disable = deactivate power saving mode.
34
EX17908 Web-Smart Switch User Guide
Port Settings
Field
Description
Port
Number corresponding to each port on the switch.
Link
Read-only fields that show whether the switch ports are up or down.
Up ports are color-coded green and show the speed of the connection. In the example above, port 4 is
operating at 1000 Mbps full-duplex.
Down ports are color-coded red.
Mode
Configures the negotiation mode for the switch port. Choices are:
Auto Speed = port adjusts automatically to the speed and duplex setting of the device connecting to this port.
(default)
10 Half = port is configured for 10 Mbps half-duplex transmission only.
10 Full = port is configured for 10 Mbps full-duplex transmission only.
100 Half = port is configured for 100 Mbps half-duplex transmission only.
100 Full = port is configured for 100 Mbps full-duplex transmission only.
1000 Half = port is configured for 1000 Mbps half-duplex transmission only.
1000 Full = port is configured for 1000 Mbps full-duplex transmission only.
Disabled = port is out of action and not operational.
Flow Control
Enables or disables flow control for each port.
Check = enable flow control. Flow control handles situations where a transmitting computer is sending data
faster than a receiving machine can handle it. The IEEE 802.3x standard specifies a PAUSE flow control
mechanism communicated via MAC Control frames in full duplex Ethernet link segments. Like jumbo frames,
the PAUSE mechanism requires all device in the data flow path to support it. By default, flow control is
enabled on all switch ports. In small networks, however, you may want to disable flow control if you experience
throughput loss or low performance.
Uncheck = disable flow control.
The port settings appear in the center of the Port Configuration page. Each row of the page
corresponds to one port. The following table describes the port settings.

Description
Port
Number corresponding to each port on the switch.
VLAN aware Enabled
Enables or disables VLAN awareness for each port.
Checked = makes the port VLAN-aware. VLAN aware ports use VLAN-tagged frames to determine the
destination VLAN of a frame. VLAN-aware ports strip the VLAN tag from received frames and insert the tag
into transmitted frames (except for the PVID).
Unchecked = makes the port VLAN-unaware. VLAN unaware ports do not strip the tag from received frames
or insert the tag into transmitted frames.
Ingress Filtering
Enabled
Enables or disables ingress filtering for each port.
Checked = enable ingress filtering. The switch discards incoming frames for VLANs that do not include this
ingress port in their member set.
Unchecked = disables ingress filtering.
Packet Type
Sets the interface to accept all frame types, including tagged or untagged frames, or only tagged frames. Choices
are:
All = port can accept incoming tagged and untagged packets. Any received packets that are untagged are
assigned to the default VLAN. Any tagged packets are dropped, unless the port is a member of the VLAN
identified by the VLAN tag in the packet.
Tagged Only = port drops untagged packets and receives tagged packets only. Tagged packets are dropped,
unless the port is a member of the VLAN identified by the VLAN tag in the packet. Switches should be
connected to each other with the Packet Type set to Tagged Only.
2. Complete the settings in the page, and then click Apply.
EX17908 Web-Smart Switch User Guide
40
Field
Description
Pvid
The PVID (Port VLAN ID) is associated with untagged, ingress packets and assigned to untagged frames
received on the specified interface. The PVID has no effect on ports whose Packet Type is set to “Tagged Only.”
You cannot remove a port from VLAN 1, unless its PVID is changed to a value other than 1. Outgoing packets are
tagged unless the packet’s VLAN ID is the same as the PVID.
If the PVID is set to “None”, all outgoing packets are tagged.
If you select “Tagged Only” mode for a port, we recommend setting the PVID to “None” as the standard
configuration.

Aggregation/Trunking Page
Path: Configuration > Aggregation
The Aggregation/Trunking Configuration page lets you bundle (or aggregate”) multiple links
together to act as a single physical link for increased throughput. Bundling links provides load
balancing and redundancy of links in a switched inter-network.
In reality, the link does not have an inherent total bandwidth equal to the sum of its
component physical links. Traffic in a trunk is distributed across an individual link within the
trunk in a deterministic method using a hash algorithm. The hash algorithm applies load
balancing to the ports in the trunk automatically. A port failure within the trunk group redirects
network traffic to the remaining ports. Load balancing is maintained whenever a link in a trunk
is lost or returned to service.
You can configure up to four trunks. To assign ports to a trunk:
1. On the Group 1 row, click the trunk numbers you want to aggregate.
2. Click Apply.
3. To configure up to three additional trunks, repeat steps 1 and 2 on the next Group row.

The IGMP Configuration page lets you configure the switch’s Internet Group Management
Protocol (IGMP) settings. IGMP allows the switch to “listen in” on IGMP conversations
between hosts and routers by processing Layer 3 IGMP packets sent in a multicast network.
When IGMP is enabled, the switch analyzes all IGMP packets between hosts connected to
the switch and multicast routers in the network.
When the switch hears an IGMP report from a host for a given multicast group, the switch
adds the host’s port number to the multicast list for that group.

the switch and the connected
device are not the same.
Configure the switch and the attached device to auto-negotiate.
A segment or device is
not recognized as part of
the network.
One or more devices are not
connected properly or cabling
does not meet Ethernet
guidelines.
Verify that the cabling is correct.
Be sure all connectors are securely positioned in the required ports.
Equipment may have been disconnected accidentally.
Collisions are occurring
on the connected
segment.
Some collisions are normal
when the connection is
operating in half-duplex
mode.
Recheck the settings of the device attached to the switch port.
Be sure the switch and the attached device are using the same duplex
setting.
Be sure the switch and the attached device are set to auto-negotiate.
Check and, if necessary, change the settings on the Configuration >
Storm Control page (see page 51).
Link/ACT LED is flashing
continuously on all
connected ports and the
network is disabled.
A network loop (redundant
path) has been created.
Use the RSTP System Configuration to use the Rapid Spanning Tree
Protocol to eliminate loops (see page 43).
Break the loop by ensuring that there is only one path from any networked
device to any other networked device.

Additional Troubleshooting Suggestions
If the suggestions in Table 5-1 do not resolve your problem, refer to the troubleshooting
suggestions in this section.
Network Adapter Cards
Be sure the network adapter cards installed in the PC used to configure the switch are in
working condition and the latest software driver has been installed.
Configuration
If problems occur after altering the switch’s network configuration, restore the original
connections and determine the problem by implementing the new changes one step at a time.
Be sure cable distances, repeater limits, and other physical 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 management interface (see “Warm Restart Page” on page
60). If the problem continues, contact EtherWAN Systems technical support.
Auto-Negotiation
The 10/100 Mbps ports negotiate the correct duplex mode and speed if the switch is
configured for auto-negotiation (this is the switch’s default setting) and the device at the other
end of the link supports auto-negotiation. If the device does not support auto-negotiation, the
switch determines only the speed correctly and the duplex mode defaults to half-duplex.
