After the GEP-2671/GEP-2672 has been finished configuration the it interface, you can browse it. For instance, type http://192.168.1.1 in the address row in a browser, it will show the following screen and ask you inputting username and password in order to login and access authentication.

The default username is “admin” and password is admin. For the first time to use, please enter the default username and password, and then click the <Login> button. The login process now is completed. In this login menu, you have to input the complete username and password respectively, the GEP-2671/GEP-2672 will not give you a shortcut to username automatically. This looks inconvenient, but safer.

In the GEP-2671/GEP-2672, it supports a simple user management function allowing only one administrator to configure the system at the same time. If there are two or more users using administrator’s identity, it will allow the only one who logins first to configure the system. The rest of users, even with administrator’s identity, can only monitor the system. For those who have no administrator’s identity, can only monitor the system. There are only a maximum of three users able to login simultaneously in the GEP-2671/GEP-2672.

NOTE:

When you login the Switch WEB to manager. You must first type the Username of the admin. Password was blank, so when you type after the end Username, please press enter. Management page to enter WEB.

When you login GEP-2671/GEP-2672 series switch Web UI management, you can use both ipv4 ipv6 login to manage

To optimize the display effect, we recommend you use Microsoft IE 6.0 above, Netscape V7.1 above or FireFox V1.00 above and have the resolution 1024x768. The switch supported neutral web browser interface

NOTE:

AS GEP-2671/GEP-2672 the function enable dhcp, so If you do not have DHCP server to provide ip addresses to the switch, the Switch default ip 192.168.1.1

CONNECTING NETWORK DEVICES

TWISTED-PAIR DEVICES

CABLING GUIDELINES

The switch is designed to be connected to 10, 100 or 1000Mbps network cards in PCs and servers, as well as to other switches and hubs. It may also be connected to remote devices using optional SFP transceivers.

Each device requires an unshielded twisted-pair (UTP) cable with RJ-45 connectors at both ends. Use Category 5, 5e or 6 cable for 1000BASE-T connections, Category 5 or better for 100BASE-TX connections.

The RJ-45 ports on the switch support automatic MDI/MDI-X pin-out configuration, so you can use standard straightthrough twisted-pair cables to connect to any other network device (PCs, servers, switches, routers, or hubs).

See Appendix B for further information on cabling.

CAUTION: Do not plug a phone jack connector into an RJ-45 port. This will damage the switch. Use only twisted-pair cables with RJ-45 connectors that conform to FCC standards.

CONNECTING TO PCS, SERVERS, HUBS AND SWITCHES

Step1. Attach one end of a twisted-pair cable segment to the device’s RJ-45 connector.

Figure 16: Making Twisted-Pair Connections

Step2. If the device is a network card and the switch is in the wiring closet, attach the other end of the cable segment to a modular wall outlet that is connected to the wiring closet. (See the section “Network Wiring Connections.”) Otherwise, attach the other end to an available port on the switch.

Make sure each twisted pair cable does not exceed 100 meters (328 ft) in length.

NOTE: Avoid using flow control on a port connected to a hub

unless it is actually required to solve a problem. Otherwise back pressure jamming signals may degrade overall performance for the segment attached to the hub.

Step3. As each connection is made, the Link LED (on the switch) corresponding to each port will light green (1000 Mbps) or amber (100 Mbps) to indicate that the connection is valid.

NETWORK WIRING CONNECTIONS

Today, the punch-down block is an integral part of many of the newer equipment racks. It is actually part of the patch panel. Instructions for making connections in the wiring closet with this type of equipment follows.

Step1. Attach one end of a patch cable to an available port on the switch, and the other end to the patch panel.

Step2. If not already in place, attach one end of a cable segment to the back of the patch panel where the punch-down block is located, and the other end to a modular wall outlet.

Step3. Label the cables to simplify future troubleshooting. See “Cable Labeling and Connection Records” on page 29

Figure 2-2.1: The time configuration

Parameter description:

Clock Source:

To click what clock source for the GEP-2671/GEP-2672. You can select “Use local Settings” or “Use NTP Server” for GEP-2671 time clock source.

Local Time:

Show the current time of the system.

Time Zone Offset:

Provide the timezone offset relative to UTC/GMT. The offset is given in minutes east of GMT. The valid range is from -720 to 720 minutes

Daylight Saving:

Daylight saving is adopted in some countries. If set, it will adjust the time lag or in advance in unit of hours, according to the starting date and the ending date. For example, if you set the day light saving to be 1 hour. When the time passes over the starting time, the system time will be increased one hour after one minute at the time since it passed over. And when the time passes over the ending time, the system time will be decreased one hour after one minute at the time since it passed over.

The switch supports valid configurable day light saving time is –5 ~ +5 step one hour. The zero for this parameter means it need not have to adjust current time, equivalent to in-act daylight saving. You don’t have to set the starting/ending date as well. If you set daylight

saving to be non-zero, you have to set the starting/ending date as well; otherwise, the daylight saving function will not be activated.

Time Set Offset:

Provide the Daylight saving time set offset. The offset is given in minutes east of GMT. The valid range is from 1 to 1440 minutes. default is 60 mins

Daylight Savings Type:

Provide the Daylight savings type selection. You can select “ By Dates” or “Recurring” two type for Daylight saving type.

From:

To configure when Daylight saving start date and time, the format is “YYYY-MM-DD HH:MM”.

To:

To configure when Daylight saving end date and time, the format is “YYYY-MM-DD HH:MM”.

NOTE: The under “from” and “to” was displayed what you set on the “From” and “To” field information.

2-2.2 NTP

NTP is Network Time Protocol and is used to sync the network time based Greenwich Mean Time (GMT). If use the NTP mode and select a built-in NTP time server or manually specify an user-defined NTP server as well as Time Zone, the switch will sync the time in a short after pressing <Apply> button. Though it synchronizes the time automatically, NTP does not update the time periodically without user’s processing.

Time Zone is an offset time off GMT. You have to select the time zone first and then perform time sync via NTP because the switch will combine this time zone offset and updated NTP time to come out the local time, otherwise, you will not able to get the correct time. The switch supports configurable time zone from –12 to +13 step 1 hour.

Default Time zone: +8 Hrs.

Web Interface

To configure Time in the web interface:

1.Click SYSTEM, NTP.

2.Specify the Time parameter in manual parameters.

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 only appear once. It can also represent a legally valid IPv4 address. For example, '::192.1.2.34'.

Buttons

These buttons are displayed on the NTP page:

Save – Click to save changes.

Reset - Click to undo any changes made locally and revert to previously saved values.

2-3 Account

In this function, only administrator can create, modify or delete the username and password. Administrator can modify other guest identities’ password without confirming the password but it is necessary to modify the administrator-equivalent identity. Guest-equivalent identity can modify his password only. Please note that you must confirm administrator/guest identity in the field of Authorization in advance before configuring the username and password. Only one administrator is allowed to exist and unable to be deleted. In addition, up to 4 guest accounts can be created.

Privilege Level :

The privilege level of the user. The allowed range is 1 to 15. If the privilege level value is 15, it can access all groups, i.e. that is granted the fully control of the device. But others value need to refer to each group privilege level. User's privilege should be same or greater than the group privilege level to have the access of that group. By default setting, most groups privilege level 5 has the read-only access and privilege level 10 has the read-write access. And the system maintenance (software upload, factory defaults and etc.) need user privilege level 15. Generally, the privilege level 15 can be used for an administrator account, privilege level 10 for a standard user account and privilege level 5 for a guest account.

Parameter description:

Group Name

The name identifying the privilege group. In most cases, a privilege level group consists of a single module (e.g. LACP, RSTP or QoS), but a few of them contains more than one. The following description defines these privilege level groups in details:

System: Contact, Name, Location, Timezone, Log.

Security: Authentication, System Access Management, Port (contains Dot1x port, MAC based and the MAC Address Limit), ACL, HTTPS, SSH, ARP Inspection and IP source guard.

IP: Everything except 'ping'.

Port: Everything except 'VeriPHY'.

Diagnostics: 'ping' and 'VeriPHY'.

Maintenance: System Reboot, System Restore Default, System Password, Configuration Save, Configuration Load and Firmware Load. WebUsers, Privilege Levels and everything in Maintenance.

Privilege Levels

Every group has an authorization Privilege level for the following sub groups: configuration read-only, configuration/execute read-write, status/statistics read-only, status /statistics read-write (e.g. for clearing of statistics). User Privilege should be same or greater than the authorization Privilege level to have the access to that group.

2-4 IP

IP is an acronym for Internet Protocol. It is a protocol used for communicating data across an internet network.

IP is a "best effort" system, which means that no packet of information sent over is assured to reach its destination in the same condition it was sent. Each device connected to a Local Area Network (LAN) or Wide Area Network (WAN) is given an Internet Protocol address, and this IP address is used to identify the device uniquely among all other devices connected to the extended network.

The current version of the Internet protocol is IPv4, which has 32-bits Internet Protocol addresses allowing for in excess of four billion unique addresses. This number is reduced drastically by the practice of webmasters taking addresses in large blocks, the bulk of which remain unused. There is a rather substantial movement to adopt a new version of the Internet Protocol, IPv6, which would have 128-bits Internet Protocol addresses. This number can be represented roughly by a three with thirty-nine zeroes after it. However, IPv4 is still the protocol of choice for most of the Internet.

2-4.1 IPV4

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 a establish a default gateway between the switch and management stations that exist on another network segment.
