Initial
Configuration
This chapter instructs you how to configure and manage the GTP-2880
through the web user interface. With this facility, you can easily access
and monitor through any one port of the switch all the status of the switch,
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.
The default values of the GTP-2880 are listed in the table below:
After the GTP-2880 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 empty. 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 switch will not give you a shortcut to username
automatically. This looks inconvenient, but safer.
In the switch, 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 switch.

CONNECTING
NETWORK
DEVICES
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.
TWISTED-PAIR
DEVICES
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
CABLING
GUIDELINES
The RJ-45 ports on the switch that support automatic
MDI/MDI-X pin-out configuration, so you can use
standard straight-through twisted-pair cables to
connect to any other network device (PCs, servers,
switches, routers, or hubs).
C
AUTION
:
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.
See Appendix B for further information on cabling.
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
5
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.

Patch-Down Block
Wall
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.
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

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.

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