• 400-4TX MDA Not supported on the Accelar Series Modules (see

Table 2 on page 2)

• 8100-4TX MDA Supports BayStack 350/450, BayStack 410, and

Accelar Series Modules (see Table 2 on page 2)

Both models use four 10/100BASE-TX RJ-45 (8-pin modular) port connectors to attach Ethernet devices.

The RJ-45 ports are configured as media-dependent interface-crossover (MDI-X) connectors. These ports connect over straight cables to the network interface controller (NIC) card in a node or server, similar to a conventional Ethernet repeater hub. If you are connecting to another Ethernet hub or Ethernet switch, you need a crossover cable unless an MDI connection exists on the associated port of the attached device.

The 10/100BASE-TX MDA ports can operate at either 10 Mb/s or 100 Mb/s. The port speed is determined through autonegotiation with its connecting device.

Table 3 describes the 10/100BASE-TX MDA components and LEDs.

100BASE-FX MDAs

Warning: Fiber optic equipment can emit laser

or infrared light that can injure your eyes. Never look into an optical fiber or connector port. Always assume that fiber optic cables are connected to a light source.

Vorsicht: Glasfaserkomponenten können Laserlicht bzw. Infrarotlicht abstrahlen, wodurch Ihre Augen geschädi gt werden können. Schauen Sie niemals in einen Glasfaser-LWL oder ein Anschlußteil. Gehen Sie stets davon aus, daß das Glasfaserkabel an eine Lichtquel le angeschlossen ist.

Avertissement: L’équipement à fibre optique peut émettre des rayons laser ou infrarou ges qui risquent d’entraîner des lésions oculaires. Ne jamais regarder dans le port d’un connecteur ou d’un câble à fibre optique. Toujours supposer que les câbles à fibre optique sont raccordés à une source lumineuse.

Advertencia: Los equipos de fibra óptica pueden emitir radiaciones de láser o infrarrojas que pueden dañar los ojos. No mire nunca en el interior de una fibra óptica ni de un puerto de conexión. Suponga siempre que los cables de fibra óptica están conectados a una fuente luminosa.

Avvertenza: Le apparecchiature a fibre ottiche emettono raggi laser o infrarossi che possono risultare dannosi per gli occhi. Non guardare mai direttamente le fibre ottiche o le porte di collegamento. Tenere in considerazione il fatto che i cavi a fibre ottiche sono collegati a una sorgente luminosa.
