Switch — Rear View Detail 17

10BASE-T/The Switch has 8 auto-negotiating 10BASE-T/100BASE-TX ports 100BASE-TX Ports configured as Auto MDI/MDI-X. These ports automatically provide the

appropriate connection. The default state for 10/100 Mbps ports is auto-negotiation enabled, where the speed, duplex and flow control modes are negotiated.

Alternatively, you can manually set these ports to 10BASE-T half duplex, 10BASE-T full duplex, 100BASE-TX half duplex, 100BASE-TX full duplex and manually enable or disable flow control. The maximum segment length is 100 m (328 ft) over Category 5 twisted pair cable.

If you disable auto-negotiation, Auto MDI/MDI-X will also be disabled.

The Switch will supply up to 15.4W of power through ports 1, 2, 5 and 6 in conformance to the 802.3af specification. The Switch incorporates a PoE Status LED on the front panel, which indicates when power is being delivered to a device connected to one of these ports.

10BASE-T/The Switch 9 has one auto-negotiating

100BASE-TX/10BASE-T/100BASE-TX/1000BASE-T port configured as Auto MDI/MDI-X. 1000BASE-T Port This port automatically provides the appropriate connection. The default state for the 10/100/1000 Mbps port is auto-negotiation enabled, where

the speed, duplex and flow control modes are negotiated.

Alternatively, you can manually set these ports to 10BASE-T half duplex, 10BASE-T full duplex, 100BASE-TX half duplex, 100BASE-TX full duplex or 1000BASE-T full duplex and manually enable or disable flow control.

The maximum segment length is 100 m (328 ft) over Category 5 twisted pair cable.

If you disable auto-negotiation, Auto MDI/MDI-X will also be disabled.

SFP Port The Switch 9 FX has one SFP (Small Form Factor Pluggable) port that supports Gigabit Ethernet short-wave (SX) or long-wave (LX) fiber-optic SFP transceivers, or Gigabit Ethernet 1000BASE-TX SFP transceivers. This offers you the flexibility of using SFP transceivers to provide connectivity between the Switch and a 1000 Mbps core network or to create a high capacity aggregated link between two workgroups.

When using fiber-optic SFP transceivers, the only state for this port is auto-negotiation enabled. As the speed and duplex modes are fixed by the media type, only the flow control is negotiated with the link partner.
