12CHAPTER 1: INTRODUCING THE OFFICECONNECT MANAGED SWITCH 9 AND SWITCH 9 FX

About the Switch The Switch is a 10/100 Mbps Ethernet Switch, which consists of:

■8 10BASE-T/100BASE-TX ports

and either:

■One 10BASE-T/100BASE-TX/1000BASE-T (10/100/1000) port or

■One 100BASE-FX LC port and one SFP port

The 100BASE-FX and SFP port is a combination port. When an SFP module is inserted it has priority over the 100BASE-FX port of the same number. The corresponding 100BASE-FX port is disabled when an SFP module is present.

The Switch supports Power over Ethernet on ports 1, 2, 5 and 6. If you plug in a compatible (IEEE 802.3af compliant) device, it will be automatically detected and power supplied to it. Power over Ethernet is enabled on these ports by default.

Summary of Table 3 summarizes the hardware features that are supported by the
