Introduction
The eG8G Switches are high-performance Gigabit Ethernet devices designed for the
network core. They provide eight 1000 Mbps ports that can significantly improve the performance
of your network’s backbone, and deliver the throughput needed to support a broad range of
advanced network applications.
With 16 Gigabits of aggregate bandwidth, these switches can provide the quickest solution to
meeting the growing demands on your network’s limited resources. This model offers eight
1000BASE-T RJ-45 twisted-pair ports slots. Each 1000 Mbps port can support high-bandwidth
connectivity within or between workgroups, and increased capacity for server farms, giving your
users faster access to network-wide resources.
To manage the switch, you can make a direct connection to the console port on the switch’s rear
panel.
You can configure the switch’s wide array of advanced features, such as:
•Full-duplex flow control (IEEE 802.3x)
•Broadcast storm control (broadcast packets surpressed at a configurable threshold)
•Port mirroring (for real-time debugging without affecting the target port)
•VLAN support for up to 32 groups, port-based or with 802.1Q VLAN tagging
•Support 4K VLan Tag
•Quality of Service supports two levels ofpriority with Weighted Fair Queueing

Installing the Switch
Before installing the switch verify that you have all the items listed under “Package Contents.” If
any of the items are missing or damaged, contact your local distributor. Also be sure you have all
the necessary tools and cabling before installing the switch. Note that this switch can be installed
on any suitably large flat surface or in a standard EIA 19-inch rack.
Package Contents
This package includes:
Description of Hardware
The Smart Switch contains eight 1000BASE-T RJ-45 twisted-pair ports. A serial port is provided
on the rear panel for out-of-band console configuration. The AC power socket is located on the
rear panel.
The RJ-45 ports operate at 1000 Mbps, 100 Mbps, and 10 Mbps with support for auto-negotiation
of speed, duplex mode, and flow control. When using auto-negotiation, the transmission mode and
flow control can be automatically set if this feature is also supported by the attached device.
The switches also include an LED display panel for key system and port indications that simplify
installation and network troubleshooting.

Mounting the Switch
These switches can be placed directly on your desktop, or mounted in a rack.
Before you start installing the switch, make sure you can provide the right operating environment,
including power requirements, sufficient physical space, and proximity to other devices that are to
be connected. Verify the following requirements:
• Power requirements: 100 to 240 VAC (± 10%) at 50 to 60 Hz (± 3Hz). The switch's power
supply automatically adjusts to the input voltage level.
• The switch should be located in a cool dry place, with at least 10 cm (4 in.) of space on the sides
for ventilation.
• Place the switch out of direct sunlight, and away from heat sources or areas with a high amount
of electromagnetic interference.
• If you intend to mount the switch in a rack, make sure you have all the necessary mounting
screws, brackets, bolts and nuts, and the right tools.
• Check if network cables and connectors needed for installation are available.
Mounting Switches in a Rack
Please comply with the following instructions to ensure that
the switch is securely mounted in the rack.
1. Use a standard EIA 19-inch rack.
2. Use the brackets and screws supplied in the rack
mounting kit.
3. Use a Philips screwdriver to attach the brackets to the
side of the switch.
4. Position the switch in the rack by lining up the holes in
the brackets with the appropriate holes on the rack, and
then use the rack-mount screws to mount the switch in
the rack.

Connecting the Switch System
Making a Connection to an RJ-45 Port
The RJ-45 ports on the 1000BASE-T model operate at 10 Mbps, 100 Mbps, and 1000 Mbps, full
and half duplex, with support for auto-negotiation of speed, duplex mode and flow control. You
can connect any RJ-45 port on the switch to any server or workstation, or uplink to a network
device such as another switch or a router. The 1000BASE-T standard uses four pairs of Category 5
twisted-pair cable for connections up to a maximum length of 100 m (328 feet).
Note: For 1000 Mbps operation, you should first test the cable installation for IEEE 802.3ab
1000BASE-T compliance. See “1000BASE-T Cable Requirements” on page 23 for more
information.
1. Prepare the devices you wish to network. For 1000 Mbps operation, make sure that servers
and workstations have installed 1000BASE-T network interface cards. Other network
devices should have RJ-45 ports that comply with the IEEE 802.3ab 1000BASE-T standard.
2. Prepare shielded or unshielded twisted-pair cables (straight-through or crossover) with RJ-45
plugs at both ends. Use 100-ohm Category 5 (Category 5e or better is recommended) cable
for 1000 Mbps Gigabit Ethernet connections.
3. Connect one end of the cable to the RJ-45 port on the other device, and the other end to any
available RJ-45 port on the switch. When inserting an RJ-45 plug, be sure the tab on the plug
clicks into position to ensure that it is properly seated.
Caution: Do not plug a phone jack connector into any RJ-45 port. This may damage the switch.
Instead, use only twisted-pair cables with RJ-45 connectors that conform with FCC standards.
Notes: 1. For 1000 Mbps operation, all four wire pairs in the cable must be connected.
2. 1000BASE-T ports support auto MDI/MDI-X, which means that at any operating speed
(10, 100, or 1000 Mbps), either straight-through or crossover cables can be used to connect
to any server, workstation, or other network device. (Refer to “Port and Cable
Assignments” on page 22 for more information.)
3. Make sure each twisted-pair cable does not exceed 100 meters (328 feet).
Powering On the Switch
1. Plug the power cord into the power socket on the rear of the switch, and the other end into a
power outlet. (If you have purchased a redundant power supply, plug it into the “DC INPUT”
receptacle on the rear of the switch.)
2. Check the LED marked Power on the front panel to see if it is on. The unit will automatically
select the setting that matches the connected input voltage. Therefore, no additional
adjustments are necessary when connecting it to any input voltage within the range marked
on the rear panel.
Note: The unit supports a “hot remove” feature which permits you to connect or disconnect cables
without powering off the switch and without disrupting the operation of the devices attached to
the switch.

5
Verifying Port Status
Check each connection by viewing the port indicator LEDs, as shown in the following figure and
table.
Verifying System Operation
Verify that all attached devices have a valid connection. The switch monitors the link status for
each port. If any device is properly connected to the switch, the Link indicator will light up for the
corresponding port. If the Link indicator fails to light when you connect a device to the switch,
check the following items:
• Be sure all network cables and connectors are properly attached to the connected device and the
switch.
• See if your cable is functioning properly by using it for another port and attached device that
displays valid indications when connected to the network.
• Be sure not to exceed the maximum length for the type and rating of fiber cable you are using.
Refer to the tables on the preceding page.

Applications
This switch segments your network, significantly increasing both bandwidth and throughput. Each
port on the switch can be attached to any Gigabit Ethernet-compliant device, such as another
switch or a server’s network adapter. All switch ports can operate at 1000 Mbps full duplex,
providing 2 Gbps of bandwidth to the attached device.
Bridging Functions - This switch provides fully transparent bridging functions. It automatically
learns each node address and uses the addresses to forward traffic. When traffic passes between
devices attached to different ports on the switch, the high-speed switching fabric forwards the
packets.
Switching Functions - Store-and-forward switching is used to forward traffic to other ports. This
scheme ensures data integrity and provides a clean data stream.
Configuration Options - This switch is designed to operate as a high-bandwidth backbone switch.
It segments the core of the network, providing full-duplex switched links to workgroup switches or
high-speed servers. The switch offers redundant power supply backup and also supports a host of
advanced management features that are required for efficient control of today’s network traffic.

7
Configuring the Switch from the Console Port
For advanced management capability, the onboard management agent provides a menu-driven
system configuration program. This program can be accessed by a direct connection to the serial
port on the rear panel.
The system configuration program supports management functions such as:
• Enable/disable any port
• Set the communication mode for any port
• Port trunking with 2, 3, or 4 members per trunk
• Port mirroring
• Configure the VLAN mode of the switch
• Configure port-based priority
• Display system information or statistics
• Restart the system – restoring factory defaults
• Changing the password
Required Connections
Attach a VT100 compatible terminal or a PC running a terminal emulation program to the serial
port on the switch’s rear panel. Use the null-modem cable provided with this package, or use a
null-modem connection.
When attaching to a PC, set terminal emulation type to VT100, specify the port used by your PC
(i.e., COM 1~4), and then set communications to 8 data bits, 1 stop bit, no parity, and 38400 bps.
Also be sure to set flow control to “none.”

8
Log-in Screen
Once a direct connection to the serial port is established, the log-in screen for the onboard
configuration program appears as shown below.
If this is your first time to log into the configuration program, then the default password is
“admin.” This password gives Read/Write access to all configuration parameters and statistics.
You should define a new password, record it and put it in a safe place. Select System Configuration
from the Main Menu and enter a new password for the administrator. Note that passwords can
consist of up to 15 alphanumeric characters and are not case sensitive.
You are allowed three attempts to enter the correct password; on the third failed attempt the current
connection is terminated.

12
Configuring Port Trunks
Ports can be combined into an aggregate link to increase the bandwidth of a network connection or
to ensure fault recovery. You can configure trunks between any two ES4008A switches. The ports
on this switch can be grouped into a trunk consisting of two, three or four ports, creating an
aggregate bandwidth up to 4, 6, or 8 Gbps. Besides balancing the load across each port in the
trunk, the additional ports provide redundancy by taking over the load if another port in the trunk
fails. However, before making any physical connections between devices, use the Port Trunking
Configuration menu to specify the trunk on the devices at both ends. When using a port trunk,
remember that:
• Ports can only be assigned to one trunk.
• The ports at both ends of a connection must be configured as trunk ports.
• The ports at both ends of a trunk must be configured in an identical manner, including
communication mode, and VLAN assignments.
• All the ports in a trunk have to be treated as a whole when moved from/to, added or deleted from
a VLAN.
• The trunk must be enabled prior to connecting any cable between the switches to avoid creating
a loop.

13
You can use the Port Trunking Configuration screen to set up port trunks as shown below:
The port groups permitted include:
To add a trunk, select <Add>. To delete a trunk, highlight the required entry and select “Delete
trunk # setting.” Before disconnecting a port trunk, take the following steps:
• Before removing a port trunk via the configuration menu, you must disable all the ports in the
trunk or remove all the network cables. Otherwise, a loop may be created.
• To disable a single link within a port trunk, you should first remove the network cable, and then
disable both ends of the link via the configuration menu. This allows the traffic passing across
that link to be automatically distributed to the other links in the trunk, without losing any
significant amount of traffic.

Using a Mirror Port for Analysis
You can mirror traffic from any source port to port 8 for real-time analysis. You can then attach a
logic analyzer or RMON probe to the target port and study the traffic crossing the source port in a
completely unobtrusive manner. When mirroring port traffic, note that the target port must be
included in the same VLAN as the source port.
You can use the Mirror Configuration Port screen to mirror one or any ports to the port 8 as shown
below. The default is that port mirroring is disabled.

Active Enables or disables port mirroring.

15
Configuring Virtual LANs
You can use the VLAN configuration menu to assign any port on the switch to any of up to 32
LAN groups. In conventional networks with routers, broadcast traffic is split up into separate
domains. Switches do not inherently support broadcast domains. This can lead to broadcast storms
in large networks that handle traffic such as IPX or NetBeui. By using IEEE 802.1Q compliant
VLANs, you can organize any group of network nodes into separate broadcast domains, thus
confining broadcast traffic to the originating group. This also provides a more secure and cleaner
network environment. You can use the Modify VLAN screen to configure VLAN membership,
Port VLAN ID and VLAN tagging.
Smart Switch : VLAN Table (1to8)

< Return > <Config> <Delete>
Use arrow keys to move. <Space> to make change.
Parameter Description
VLAN The ID for the VLAN currently displayed.
Range: 1-32
Member Set P or S indicates that the port belongs to this VLAN. P also indicates that the
PVID of the port is set to that of this VLAN.*
Untag Set If a port is set to U it indicates that the port is untagged. In order to
communicate with a device that does not support VLAN tagging, it will strip
VLAN tags from all frames transmitted out of the switch from this port.
* All ports by default are members of VLAN 1 with PVID 1. Ports may belong to multiple VLANS but must have
only one PVID. If a port is entered as a member of another VLAN with the PVID set to the VLAN ID of that
VLAN, it will appear as a static member of VLAN 1. It may then be removed from VLAN 1 if required.

16
Priority Configuration
This switch supports Quality of Service (QoS) by using four priority queues from 0 (lowest
priority), to 3 (highest priority). Inbound frames that do not have priority tags are tagged with the
input port’s default priority tag, and then placed in the appropriate priority queue at the output port.
Up to eight separate traffic classes are defined in IEEE 802.1p.
