Product Description
The D-Link DFE-2600 series dual-speed stackable Ethernet/Fast Ethernet
hubs are designed to allow easy migration and integration between 10Mbps
Ethernet and 100Mbps Fast Ethernet, while providing manageability and
flexibility in cable connections.
The DFE-2600 hubs can operate with either IEEE 802.3 10BASE-T connections (twisted-pair Ethernet operating at 10 megabits per second), or IEEE
802.3u 100BASE-TX connections (twisted-pair Fast Ethernet operating at
100 megabits per second). All of the twisted-pair ports support NWay autonegotiation, allowing the hub to automatically detect the speed of a network
connection. This means you can connect all of your Ethernet and Fast Ethernet hosts to a DFE-2600 series hub stack, without any rewiring required when
a host is upgraded from 10Mbps to 100Mbps.
The DFE-2600 series hubs, available in 16-port and 24-port models, can be
stacked with up to five hubs in a stack. A stack of five 24-po rt hubs gives a
total of 120 Ethernet or Fast Ethernet ports. A DFE-2600 series hub stack
operates as a Class II Fast Ethernet repeater, allowing it to be linked to
another Class II Fast Ethernet stack in the same collision domain.
Introduction 1
Dual-Speed Stackable Hubs Us er’s Guide
In the basic configuration, the 10Mbps and 100Mbps segments are separate
and do not intercommunicate. An optional DFE-260S switch module (included with the DFE-2616x, DFE-2624x, DFE-2616ix, and DFE-2624ix) can
be installed in any hub in the stack, making it possible to transp arently br idge
between the 10Mbps and 100Mbps segments. In a managed hub stack, more
than one DFE-260S module can be used to provide redundancy if the two
modules are both in the primary master hub segment..
Other add-in modules are also available, providing 100BASE-TX, or
100BASE-FX connections. DFE-2600 series hubs each have two slots for
accepting slide-in modules.
Product Features
The list below highlights the features and specifications of the DFE-2600

Introduction 3
Dual-Speed Stackable Hubs Us er’s Guide
Dual-Speed Ethernet Hub
Technology Overview
Dual-speed Ethernet hubs have been developed to make it simpler to plan
networks containing both 10-Mbps Ethernet and 100-Mbps Fast Ethernet
technologies, especially when network hosts are being gradually migrated to
new Fast Ethernet connections.
Ethernet and Fast Ethernet workgroups, also called collision domains, are
configured in a star topology where all end-nodes (computers, servers,
bridges, etc.) branch out from a central hub. Two hubs can also be plinked’
to each other to form a much larger collision domain consisting of two linked
stars. And collision do mains can be easily interconnected thr ough switching
hubs and bridges to form a network large e nough to encompass a high-rise
building or campus environment.
A dual-speed hub is actually two repeaters in one housing. Any device that is
plugged into the hub is automatically connected (by NWay) to the fastest
repeater it can use. The 10-Mbps repeater receives Ethernet transmissions
from any port connected to it, and retransmits them to all other ports operating at 10 Mbps. Similarly, the 100-Mbps repeater retransmits Fast Ethernet
transmissions from ports operating at 100 Mbps to all other ports operating at
the same speed as shown below.

If there is a switching circuit in the hub (or in any hub in a stack), it will serve
as a bridge between the two repeaters.

The switching circuit does not, however join the 10Mbps Ethernet co llision
domain with the 100Mbps Fast Ethernet collision domain; it only allows them
to communicate. The two repeaters are two separate collision domains regardless of whether a switching circuit is present.
If a DFE-2600 series hub or hub stack is uplinked through a twisted-pair or
Uplink port to another dual-speed or Fast Ethernet hub or stack, the hub will
function as a Class II Fast Ethernet device and be subject to those connectivity rules. If it is uplinked to a 10BASE-T Ethernet hub or stack (10Mbps
only) then it will function as a normal 10BASE-T Ethernet repeater and is
then subject to those connection rules. And because it is a dual-speed hub
with two separate repeaters, it can connect to both at the same time, counting
as a repeater in each of the collision domains. For more detailed information,
please refer to Chapter 4,
Making Connections

Dual-Speed Stackable Hubs Us er’s Guide
♦ LED Indicator Panel
Refer to the next chapter,
Understanding Indicators
, for detailed infor-
mation about each of the hub LED indicators.
♦ Twisted-Pair Ports
Use any of these ports to connect stations to the hub. The ports are MDIX Nway ports, which means you can use ordinary straight-through
twisted-pair cable to connect the hub to PCs, workstations, or servers
through these ports, and the speed of the connection will be detected
automatically. If you need to connect to another device with MDI-X
ports such as another hub or an Ethernet switch, you should use a crossover cable, or connect using the Uplink port (described below). For more
information about crossover connection, see the
Crossover Cables
on page 112.
♦ Uplink Port
The Uplink port is an MDI port, which means you can connect the hub (or
hub stack) to another de vice with MDI-X p o rts using a n or di nar y straightthrough cable, making a crossover cable unnecessary.
Port 1 and the Uplink port are the same logical port, except their pinouts
are different.
Do not use both Port 1 and the Uplink port at the same
time.

Unpacking and Setup8
Rear Panel
(Note that the figure shows the rear panel for master models.)
♦ Module Slots
Used to install module options for various kinds of additional connections, as well as the DFE-260S 10Mbps/100Mbps bridge module. (In the
DFE-2616x, DFE-2616ix, DFE-2624x and DFE-2624ix, module slot 1 is
already occupied by the switch module which is standard on these models.)
♦ Daisy-Chain IN Port
When cascading a set of D-Link stackable dual-speed hubs, this port
should be connected to the Daisy-Chain OUT port o f the previous hub in
the stack (usually placed immediately above it). A cascade of five hubs
can be created in this way. The first and last hubs in the stack use only
one of the daisy-chain ports, while the others use both.
♦ Daisy-Chain OUT Port
Works in conjunction with the Daisy-Chain IN Port (see above). Connect
this port to the Daisy-Chain IN Port o f the next hub in the stack (usually
placed immediately below it), using the enclosed daisy-chain cable.
♦ Diagnostic (Console) Port -- Master Models Only

generators (such as motors), vibration, dust, and direct exposure to
sunlight.
♦
Leave at least 10cm of space at the front and rear of the hub for ventilation.
♦
Install the hub on a sturdy, level surface that can support its weight, or
in an EIA standard-size equipment rack. For information on rack installation, see the next section,
, for the acceptable temperature and humidity operating
Rack Mounting.
Unpacking and Setup10
When installing the hub stack on a level surface, attach the rubber feet to the
bottom of each device. The rubber feet cushion the hub and protect the hub
case from scratching.
Rack Mounting
The hub can be mounted in an EIA standard-size, 19-inch rack, which can be
placed in a wiring closet with other equipment. Attach the mounting brackets
at the hub front panel (one on each side), and secure them with the provid-
ed screws.
Then, use screws provided with the equipment rack to mount each hub in the
rack.

Replacing the Power Supply
The hub comes with a removable power supply for easy replacement. In the
unlikely event that the power supply fails or is damaged, follow the steps
below to replace it:
1.
Disconnect the power cord from the AC outlet.
2.
Disconnect the power cord from its connector on the rear of the hub.
3.
Using a Phillips screwdriver, remove the screws securing the power
supply to release the unit.
4.
Remove the power supply by sliding it out the rear of the chassis. Do
not plug in the power supply when it is outside the chassis! Doing so
could cause personal injury or damage to the power supply.
Unpacking and Setup12
5.
Slide the replacement power supply into the chassis, engaging the
connector carefully.
6.
Attach the power cord to the connector of the power supply and connect the other end of the power cord to the AC supply source.

Hub State Indicators
♦ Power Indicator
This indicator lights green when the hub is receiving power; otherwise, it
is off.
♦ Collision Indicators (COL10 and COL100)
These indicators indicate data collisions on the respective 10Mbps Ethernet or 100Mbps Fast Ethernet segments of the hub. (If several hubs are
stacked or linked together, all of them should detect and indicate the same
collision, since collisions span the entire network segment.) Whenever a
collision is detected, the respective COL indicator will briefly blink amber.
Understanding Indicators16
♦ Segment Utilization % (10Mbps and 100Mbps)
The utilization bar graphs provide a quick reference on the current traffic
load relative to the total available 10Mbps or 100Mbps network bandwidth. The graphs display a measure of the percentage of bandwidth in
use on the respective network segment. All data packets are counted,
whether valid or not.
♦ Hub ID Indicator
The Hub ID readout shows the ID (group) number of the hub within the
hub stack. The first time a hub is powered on within a hub stack, the
master hub in the stack assigns that hub an available ID number which is
then added to each hub factory serial number (encoded on an EEPROM
memory chip). The hub ID is then permanently assigned.
In an unmanaged stack (all slave models), all IDs will read “0” and no
permanent ID assignment is made. In a stack with a master (intelligent)
model, the master hub will detect the other hubs in the stack and automatically assign ID numbers which are then permanently saved by each
hub.
Module Indicators
The two module indicators, SLOT1 and SLOT2, indicate a good link to a
module installed in the respective slot. For the DFE-260S switch module the
indicator will come on when the module is installed. For the DFE-260FX
and DFE-260TX modules, the slot link indicator should light whenever the
module is installed and there is a valid link.

Port State Indicators
There is one port state indicator for each of the twisted-pair ports on the hub.
Each port LED status indicator reports the port link and activity status,
and shows whether or not the port has been partitioned.
The following describes each indicator and the meaning of each condition:
♦ Link (green)
The indicator of a port lights green when the port is connected to a powered Ethernet or Fast Ethernet station. If the station to which the hub is
connected is powered off, or if there is a problem with the link, the LED
will remain off.
♦ Receive (blinking green)
When information is received on a port, its indicator will blink off briefly.
Upon reception, the data will be transmitted to all other connected ports.
♦ Auto-partition (blinking amber)
The indicator of a port blinks amber when the port is automatically partitioned due to an abnormal network condition.
The hub will temporarily partition a port when too many line errors or too
many collisions are detected on the port. While the segment is automatically partitioned, the port will be isolated from the rest of the network
segment. When the problem is corrected or a valid data packet is received through the port, the port is automatically reconnected.
♦ Disabled (steady amber)
The indicator of a port is orange when the port has been manually disabled. No packet transmission or reception can occur on the port.
