Switch - Rear View Detail 17 10BASE-T/ 100BASE-TX Ports The Switch has 8 auto-negotiating 10BASE-T/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/ 100BASE-TX/ 1000BASE-T Port The Switch 9 has one auto-negotiating 10BASE-T/100BASE-TX/1000BASE-T port configured as Auto MDI/MDI-X. 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.

10BASE-T/
100BASE-TX Ports
The Switch has 8 auto-negotiating 10BASE-T/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/
100BASE-TX/
1000BASE-T Port
The Switch 9 has one auto-negotiating
10BASE-T/100BASE-TX/1000BASE-T port configured as Auto MDI/MDI-X.
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
