Gigafast EE2400-G User manual

1. Introduction
The Fast Ethernet Switch with Gigabit modules is an auto-sensing
10/100Mbps switch with two build-in 10/100/1000 Gigabit ports. This
high-performance switch is developed primarily to be used either as a
segment switch or a desktop switch.
Thus, EE2400-G can provide up to 2 additional Gigabit ports for 2 gigabit
backbone connections within your Local Area Network (LAN).
All of the network ports on the Model EE2400-G can adapt automatically to
the speed of the connected network or the PC, and ports can operate at
either 10Mbps or 100Mbps. In addition, each port can automatically negotiate
with the connected device to operate in full-duplex mode. If the connected
device is operating in half-duplex mode only, or does not have the capability
to participate in the negotiation process, the port will default to half-duplex
mode. The BaseSwitch EE2400-G supports basic management function
(Console management). Console management involves the RS-232 console
port. The functions of the console management include Trunk Setting, VLAN
Setting, and Priority etc.
EE2400-G is compliant to 10/100/1000BASE-T standards. It operates in a
protocol-independent manner, eliminating the overhead for management
software and maintenance efforts. Furthermore, it features up to 2
Copper-wired gigabit ports to enable Gigabit backbone connections for
departmental workgroups or high performance servers. LAN users can very
easily upgrade their existing Ethernet/Fast Ethernet to Gigabit networking
environment. With easy Plug-and-Play installation, EE2400-G Gigabit
Ethernet Switch offers you an effortless and inexpensive upgrade to Gigabit
network.
There is a console port at the rear panel of this EE2400-G. User can setup
per-port 10/100Mbps, Half/Full duplex configuration from the console port.
The VLAN、Trunking and Priority functions of EE2400-G is also setup from
the console port. Users can setup VLAN groups for network management or
user can setup trunking connection for switch-to-switch connection with faster
bandwidth.

AC Power Connector
This is a three-pronged power connector where the power cord should be
attached. Just plug the female end of the power cord into the connector, and
the male end of the power cord into an AC power outlet. The switch supports
an input voltages ranging from 100~240V at 50~60 Hz.
Ventilators
These two ventilators fans help circulate the cool air through the heated
components inside the switch. The air holes on both sides of the switch also
serve as heat vents to dissipate the heat. For proper ventilation, please be
careful in your installation that in any case these openings should not be
blocked. An adequate margin space for the rear and both sides of the switch
should be provided. Be reminded that without proper air circulation to
dissipate the heat, the internal components of the switch might get
overheated, which might lead to system failure.
Each cooling fan is housed in a fan tray, which ensures its proper functioning
without getting entangled with external wirings or improper tempering. The
cooling fans are endurable and work reliably to prevent your switch from
overheating. Since the switch is equipped with two cooling fans, heat
dissipation can still function if one fan stops running. But if you find either fan
not functioning properly, please contact your local dealer for replacement.

Cabling Requirements
EtherEngine 2400-G Gigabit Ethernet Switch is primarily designed as a
central switching device to provide congestion-free bandwidth to your existing
10/100/1000Mbps network. It can also provide you with up to 2 gigabit
backbones to relieve your network bottleneck. It fits well into the
10/100/1000BASE-TX cabling architecture to facilitate not only 20/200Mbps,
but also 2000Mbps full-duplex transmission speed. The auto-detecting MDI
Uplink will automatically change the regular port to an uplink port that
provides a switch-to-switch cabling extension up to 100 meters.
The table below describes which types of cable should be used in which
circumstances:
10/100/1000BASE-T connection
The 24 RJ-45 station ports (MDI-X) and the copper-wired gigabit port require
either UTP or STP cable for connection. When configuring within the
10/100/1000BASE-T cabling architecture, the UTP cabling distance should be
within a maximum distance of 100.
RJ-45 station port cable requirements:
●10BASE-T
100 ohm Category 3, 4 or 5 unshielded or shielded twisted-pair (UTP/STP)
cables.
●100BASE-TX
100 ohm Category 5 UTP/STP cables.

Straight-through/crossover cabling requirements
Under most conditions, the 24 station ports on the Switch may accept normal,
straight-through cables, i.e., standard UTP/STP cables, which are the only
ones that can be used with a RJ-45 pin layout.
Normally, 10BASE-T networks require a straight-through Cat. 3,4,5 UTP/STP
cabling system. The cabling system could be found in most existing network
installations. 100/1000BASE-T networks require Cat 5 UTP/STP cabling
system.

3-e Pin Assignments for straight-through cabling
In some circumstances, however, crossover cables may be required. If a
station port on your switch must connect to a hub/switch, you must use a
crossover cable, which ha sits transmit (TD) and receive (RD) leads crossed
over to the other end of the cable.
Note:
The pin RJ-45 assignment used in 1000BASE-T is different from in
10/100BASE-TX. Therefore, a Switch-to-Switch 1000BASE-T connection
does not require a crossover cable.
However, the 1000BASE-T gigabit port can automatically determine whether
or not it needs to cross over between pairs. Therefore, the 1000BASE-T
gigabit port does not require an external crossover cable when connecting to
another Switch.
If EE2400-G interoperates with a device that cannot automatically correct for
crossover, it makes the necessary adjustment prior to commencing
auto-negotiation. If it interoperates with a device that implements MDI/MDIX
crossover, a random algorithm as described in IEEE802.3 section 40.4.4
determines which device performs the crossover.

Connecting to Power
EE2400-G Gigabit Ethernet Switch features a universal auto-select power
supply unit, which allows a power connection to a wide range of input
voltages from 90 to 240V AC @ 50 to 60 HZ.
To establish its power connection, simply plug the female end of the power
cord into the power connector on the rear of the switch and the male end of
the power cord into a suitable power outlet. Once you have correctly plugged
in the power, you can then turn on the Power Switch to activate the switch.

The following sections will introduce to you the basics of network connectivity
in workgroup/departmental computing within Ethernet/Fast Ethernet/Gigabit
Ethernet environment.
Connectivity Rules
10/100 Mbps Connection (10BASE-T/100BASE-TX)
Ethernet connection should be configured according to the following
connectivity rules:
The maximum length for UTP cables must not exceed 100 meters from
end station to a shared-access 10BASE-T/100BASE-TX hub.
Between any two end stations in a collision domain, there may be up to
five cable segments and four intermediate repeaters at most.
If there is a path between any two end-stations containing five segments
and four repeaters, then at least two of the cable segments must be
point-to-point link segments (e.g. 10BASE-T, 10BASE-5), while the
remaining segments may be of mixed segments (e.g.: 10BASE-2 or
10BASE-5).
Copper-wired10/100/1000Mbps
Connection(10/100/1000BASE-T)
Copper-wired Fast Ethernet/Gigabit Ethernet connection should be configured
according to the following connectivity rules:
The maximum length for STP/UTP cables is 100 meters from end station
and a shared-access 100BASE-TX hub.
The 26 Port 10/100/1000Mbps N-Way Auto-negotiating gigabit Switch
can be used to build or increase the bandwidth on a network.
EE2400-G Gigabit Ethernet Switch allows a 10BASE-T or 100BASE-TX hub
to be connected to the Switch via a 4-pair UTP/STP straight-through cable

(Category 3, 4 or 5). Each cable length can be up to 100 meters long (328
feet ). The hub-to-switch connection is daisy-chain port (MDI-II) on the hub to
any of the station ports (MDI-X) on the Switch.
For a 10BASE-T or 100BASE-TX hub, the LED indicators on the Switch
should give the following signals to indicate a proper connection:
Link/Act LED indicators should be ON at green color
FDX/COL Led indicators should be ON at green color
10/100M LED indicator should be ON if connected to 10BASE-T on red
color , if connected to 100BASE-TX on green color 100BASE-TX,
otherwise it should be OFF
Switch-to-Switch Connection (10/100BASE-TX)
EE2400-G Gigabit Ethernet Switch can be connected to another switch or
other device, such as a router or bridge by a two-pair UPT/STP
Straight-through or Crossover cable (Category 3, 4, 5).
Using a Straight-through Cable
When using a straight cable, the switch-to-switch connection is done through
the daisy-chain port (MDI-II) of the Switch to any of the 10Mbps or 100Mbps
station port (MDI-X) of another switch or device.
Using a Crossover Cable
When connecting any 10/100Mbps station port (MDI-X) of other switch or
device to any station port (MDI-X) of EE2400-G Gigabit Ethernet Switch, it is
required that you use a crossover cable.
RJ-45 Gigabit Port Description
The RJ-45 Gigabit port can automatically determine whether it needs to cross
over between pairs . Therefore, the 1000BASE-T gigabit port does not require
an external crossover cable when connecting to another switch.
