Wichtige Sicherheitshinweise
1. Bitte lesen Sie sich diese Hinweise sorgfältig durch.
2. Heben Si e diese Anl e itung für den spätern Gebrauch auf.
3. Vor jedem R einigen ist das Ge rä t vom Stromnetz z u trennen. Ve rvenden Sie keine Flüssig- oder
Aerosolreiniger. A m be sten dient ein angefeucht e tes Tuch zur Reinigung.
4. Um eine Beschädi gung de s Gerätes zu vermeide n sollten Sie nur Zubehörteile verwenden, die vom
Herste ller zugelassen sind.
5. Das Ge rä t is vor Fe uc htigkeit z u schützen.
6. Bei der Aufstellung des Gerätes is t auf siche r n Stand zu acht e n. Ein Kippe n ode r Fallen könnt e
Verletzungen hervorrufen. Verwenden Sie nur sichere Standorte und beachten Sie die Aufstellhinweise
des Herstellers.
7. Die Belüftungsöffnungen dienen zur Luftzi rkulation die da s Gerät vor Ü be r hitzung schüt zt. Sorgen Sie
dafür, daß die se Öffnungen nic ht abgedeckt we rde n.
8. Beachten Sie beim Anschluß an das Stromnetz die Anschlußwerte.

References in this manual to the DFE-908 and DFE-908x hubs are frequently written simply as “hub” or “ hubs” where the text applies to all
models. Model numbers are normally used only to differentiate between
the two where necessary.
Unless differentiated by model number, all information applies to all models.

This chapter introduces the DFE-908 series stackable dual-speed Fast
Ethernet/Ethernet Hubs, as well as giving some background information
about the technology the hubs use.
Product Description
The D-Link DFE-908 series stackable dual-speed Fast Ethernet/Ethernet
Hubs are designed to allow easy migration and integration between 10Mbps
Ethernet and 100Mbps Fast Ethernet, while providing flexibility in cable
connections.
The DFE-908 series 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
Auto-Negotiation (NWay), 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-908 series hub stack, without any
rewiring required when a host i s upgrade d from 10Mbps to 100Mbps.
The DFE-908 series hubs, available in 8-port models, can be stacked with
up to five hubs in a stack. A stack of five 8-port hubs gives a total of 40
Ethernet or Fast Ethernet ports. A DFE-908 series hub stack operates as a
Introduction2
Class II Fast Ethernet repeater, allowing it to be linked to another Class II
Fast Ethernet stack in the same collision domain.
On the DFE-908, the 10Mbps and 100Mbps segments are separate and do
not intercommunicate. The DFE-908x contains a built-in switch, making it
possible to transparently bridge between the 10 Mbps and 100 Mbps segments.
Product Features
The list below highlights the features and specifications of the DFE-908
series hubs:
♦
Compatible with the IEEE 802.3 10BASE-T Ethernet and 802.3u
100BASE-TX Fast Ethernet industry standards for interoperability
with other Ethernet/Fast Ethernet network devices.
♦
Ethernet connections support Category 3 or better twisted-pair cables.
♦
Fast Ethernet connections support both shielded twisted pair and
Category 5 unshielded twisted-pair cables.
♦
Fast Ethernet connections support a maximum distance of 100 meters from end-station to hub, and a total network diameter of 205
meters.
♦
Eight NWay RJ-45 ports for connecting stations to the network.
♦
Built-in switching function (DFE-908x only) supports bridging between 10Mbps and 100Mbps segments.
Only one DFE-908x is
needed per stack.
♦
A stack can contain various D-Link dual-speed hub models.
