téléphonique central privé ou public. Raccorder seulement connecteurs de données RJ-45, systèmes de réseaux de téléphonie ou téléphones de réseaux à ces prises.

Il est possible de raccorder des câbles protégés ou non protégés avec des jacks protégés ou non protégés à ces prises de données.

WARNHINWEIS: RJ-45-Porte. Diese Porte sind geschützte Datensteckdosen. Sie dürfen weder wie normale traditionelle Telefonsteckdosen noch für die Verbindung der Einheit mit einem traditionellem privatem oder öffentlichem Telefonnetzwerk gebraucht werden. Nur RJ-45-Datenanscluße, Telefonnetzsysteme or Netztelefone an diese Steckdosen anschließen. Entweder geschützte oder ungeschützte Buchsen dürfen an diese Datensteckdosen angeschlossen werden.

The Switch has 24 10/100 Mbps auto-negotiating ports. Each port supports automatic MDI/MDI-X detection and can be connected to either a 10BASE-T, or 100BASE-TX device.

For each port, the speed and duplex mode (half duplex or full duplex for 10BASE-T and 100BASE-TX) are automatically determined by the capabilities of the connected device.

The Switch also support IEEE 802.3af-2003 standard (802.3af) Power-over-Ethernet capabilities. Each port can detect connected 802.3af-compliant network devices,

such as IP phones or wireless access points, and automatically supply the required DC power.

(2) Gigabit Combo Ports (RJ-45/SFP)

The Gigabit combo ports (RJ-45/Small Form Factor Pluggable (SFP) ports) are numbered 25 and 26. If the link connections on the SFP ports are active, the associated RJ-45 port of the same number is disabled.

The two SFP ports support fiber Gigabit Ethernet short-wave (SX) and long-wave (LX) SFP transceivers in any combination. This offers you the flexibility of using SFP transceivers to provide connectivity between the Switch and remote 1000 Mbps workgroups or to create

ahigh-capacity aggregated link backbone connection. The default active port is the SFP port. The selection of active ports can be configured via the Web interface.

The SFP port supports full duplex mode only.

SFP ports are numbered 25 and 26 on the Switch. When an SFP port is active it has priority over the 10/100/1000 port of the same number. The corresponding 10/100/1000 port is disabled when an SFP link connection is active.
