Chapter 1 Operation of Web-based Management
Initial
Configuration
This chapter instructs you ho to configure and manage the
ET42202M-S-PD through the eb user interface. With this facility, you
can easily access and monitor through any one port of the s itch all the
status of the s itch, including MIBs status, each port activity, Spanning tree
status, port aggregation status, multicast traffic, VLAN and priority status,
even illegal access record and so on.
T
he default values of the ET42202M-S-PD are listed in the table belo :
IP Address 192.168.2.1
Subnet Mask 255.255.255.0
Default
Gateway
192.168.2.254
Username admin
Password system
After the ET42202M-S-PD has been finished configuration the it interface,
you can bro se it. For instance, type http://192.168.2.1 in the address
ro in a bro ser, it ill sho the follo ing screen and ask you inputting
username and pass ord in order to login and access authentication.
The default username is “admin” and pass ord is system. For the first
time to use, please enter the default username and pass ord, and then click
the <Login button. The login process no is completed. In this login menu,
you have to input the complete username and pass ord respectively, the
ET42202M-S-PD ill not give you a shortcut to username automatically.
This looks inconvenient, but safer.
In the ET42202M-S-PD, allo ed t o or more users using administrator’s
identity to manage this s itch, hich administrator to do the last setting, it
ill be an available configuration to effect the system.

Step2.Plug the other end of the cable into an external DC po er source.
Step3.Check the front-panel LEDs as the device is po ered on to be sure the POWER LED
is lit. If not, check that the po er cable is correctly plugged in.
AC Power Connecting
You can plug or remove AC po er cord through the AC socket from AC po er source.
Step1. Insert the po er cable plug directly into the AC Socket located at the back of the
s itch.
Step2. Plug the other end of the cable into a grounded, 3-Pin, AC po er source.
Step3. Check the front-panel LEDs as the device is po ered on to be sure the POWER LED
is lit. If not, check that the po er cable is correctly plugged in.
W ARNING :
For International use, you may need to change the AC
line cord. You must use a line cord set that has been approved for
the socket type in your country.
2-1.4 Port and system status LEDs
The ET42202M-S-PD switch includes a display panel for system and port indications that simplify
installation and network troubleshooting. The LEDs, which are located on left hand side of the front

ith information on ho to contact this person. The allo ed string length is 0 to
128, and the allo ed content is the ASCII characters from 32 to 126.
System name:
An administratively assigned name for this managed node. By convention, this is
the node's fully-qualified domain name. A domain name is a text string dra n
from the alphabet (A-Za-z), digits (0-9), minus sign (-). No space characters are
permitted as part of a name. The first character must be an alpha character. And
the first or last character must not be a minus sign. The allo ed string length is 0
to 128.
System Location:
The physical location of this node(e.g., telephone closet, 3rd floor). The allo ed
string length is 0 to 128, and the allo ed content is the ASCII characters from 32
to 126.

2-1.7 IP
The IPv4 address for the switch could be obtained via DHCP Server for VLAN 1. To manually
configure an address, you need to change the switch's default settings to values that are
compatible with your network. You may also need to establish a default gateway between the
switch and management stations that exist on another network segment.
Configure the switch-managed IP information on this page
Configure IP basic settings, control IP interfaces and IP routes.
The maximum number of interfaces supported is 8 and the maximum number of routes is 32.
Web Interface
To configure an IP address in the web interface:
1. Click Configuration, System, IP.
2. Click Add Interface then you can create new Interface on the switch.
3. Click Add Route then you can create new Route on the switch
4. Click Apply

Mode:
Configure whether the IP stack should act as a Host or a Router. In Host mode, IP traffic
between interfaces will not be routed. In Router mode traffic is routed between all

interfaces.
DNS Server
This setting controls the DNS name resolution done by the switch. The following modes are
supported:
•From any DHCP interfaces
The first DNS server offered from a DHCP lease to a DHCP-enabled interface will be
used.
•No DNS server
No DNS server will be used.
•Configured
Explicitly provide the IP address of the DNS Server in dotted decimal notation.
•From this DHCP interface
Specify from which DHCP-enabled interface a provided DNS server should be
preferred.
DNS Proxy
When DNS proxy is enabled, system will relay DNS requests to the currently configured
DNS server, and reply as a DNS resolver to the client devices on the network.
IP Interfaces
Delete
Select this option to delete an existing IP interface.
VLAN
The VLAN associated with the IP interface. Only ports in this VLAN will be able to access
the IP interface. This field is only available for input when creating an new interface.
IPv4 DHCP Enabled
Enable the DHCP client by checking this box. If this option is enabled, the system will
configure the IPv4 address and mask of the interface using the DHCP protocol. The DHCP
client will announce the configured System Name as hostname to provide DNS lookup.
IPv4 DHCP Fallback Timeout
The number of seconds for trying to obtain a DHCP lease. After this period expires, a
configured IPv4 address will be used as IPv4 interface address. A value of zero disables
the fallback mechanism, such that DHCP will keep retrying until a valid lease is obtained.
Legal values are 0 to 4294967295 seconds.
IPv4 DHCP Current Lease
For DHCP interfaces with an active lease, this column show the current interface address,
as provided by the DHCP server.
IPv4 Address
The IPv4 address of the interface in dotted decimal notation.
If DHCP is enabled, this field is not used. The field may also be left blank if IPv4 operation
on the interface is not desired.
IPv4 Mask
The IPv4 network mask, in number of bits (prefix length). Valid values are between 0 and 30
bits for a IPv4 address.
If DHCP is enabled, this field is not used. The field may also be left blank if IPv4 operation
on the interface is not desired.
IPv6 Address
The IPv6 address of the interface. AIPv6 address is in 128-bit records represented as eight
fields of up to four hexadecimal digits with a colon separating each field (:). For example,
fe80::215:c5ff:fe03:4dc7. The symbol :: is a special syntax that can be used as a shorthand
way of representing multiple 16-bit groups of contiguous zeros; but it can appear only once.
It can also represent a legally valid IPv4 address. For example, ::192.1.2.34.
The field may be left blank if IPv6 operation on the interface is not desired.
IPv6 Mask

The IPv6 network mask, in number of bits (prefix length). Valid values are between 1 and
128 bits for a IPv6 address.
The field may be left blank if IPv6 operation on the interface is not desired.
IP Routes
Delete
Select this option to delete an existing IP route.
Network
The destination IP network or host address of this route. Valid format is dotted decimal
notationor a valid IPv6 notation. Adefault route can use the value 0.0.0.0or IPv6 :: notation.
Mask Length
The destination IP network or host mask, in number of bits (prefix length). It defines how
much of a network address that must match, in order to qualify for this route. Valid values
are between 0 and 32 bits respectively 128 for IPv6 routes. Only a default route will have a
mask length of 0 (as it will match anything).
Gateway
The IP address of the IP gateway. Valid format is dotted decimal notationor a valid IPv6
notation. Gateway and Network must be of the same type.
Next Hop VLAN (Only for IPv6)
The VLAN ID (VID) of the specific IPv6 interface associated with the gateway.
The given VID ranges from 1 to 4094 and will be effective only when the corresponding
IPv6 interface is valid.
If the IPv6 gateway address is link-local, it must specify the next hop VLAN for the gateway.
If the IPv6 gateway address is not link-local, system ignores the next hop VLAN for the
gateway.
