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.

WARNING: RJ-45 Ports. These are shielded RJ-45 data sockets. They cannot be used as standard traditional telephone sockets, or to connect the unit to a traditional PBX or public telephone network. Only connect RJ-45 data connectors, network telephony systems, or network telephones to these sockets.

Either shielded or unshielded data cables with shielded or unshielded jacks can be connected to these data sockets.

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.

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

When an SFP module is inserted it has priority over the 100BASE-FX port. The corresponding 100BASE-FX port is disabled when an SFP module is present.

100BASE-FX Port The Switch 9 FX has one 100BASE-FX LC port. This is a 100 Mbps fiber-optic port that can use standard multi-mode fiber-optic cable of up to 2 kilometers (1.2 miles). It uses the standard duplex LC connector that allows both the transmit and the receive fibers to be connected in the same space as an RJ-45 port.

When an SFP module is inserted it has priority over the 100BASE-FX port. The corresponding 100BASE-FX port is disabled when an SFP module is present.

Console Port The console port allows you to connect a terminal and perform local out-of-band management. The console port uses an RJ-45 to DB-9 null modem cable (supplied with the Switch) and is set to 19200 baud, 8 data bits, no parity and 1 stop bit.

The default configuration automatically detects any of the following baud rates: 1200, 2400, 4800, 9600, 19200, 38400, 57600, 115200. However, you must set the baud rate on your management device to 19200 baud if you want to view all the system initialization messages.

Power Socket The power adapter supplied with the Switch automatically adjusts its power setting to any supply voltage in the range 100-240 VAC. Only use the adapter provided with the Switch.

■No more than four Switch units are placed on top of one another, if the units are free-standing or stacked together with the stacking clip.

■The Switch is situated away from sources of conductive (electrical) dust, for example laser printers.

■The AC supply used by the Switch is separate to that used by units that generate high levels of AC noise, for example air conditioning units and laser printers.

Placing Units On If the Switch units are free-standing or stacked together with the stacking Top of Each Other clip, up to four units can be placed one on top of the other. If you are

mixing a variety of OfficeConnect Switch and Hub units, the smaller units must be positioned at the top.

If you are placing free-standing Switch units one on top of the other, you must use the supplied self-adhesive rubber pads to prevent the Switch from moving around on your desk, or when stacking with flat top OfficeConnect units. Apply the pads to the underside of each Switch, sticking one in the marked area at each corner.

Using a Stacking Use a stacking clip when stacking your Switch with other curved Clip OfficeConnect units. The stacking clip allows you to stack units neatly

and securely.

CAUTION: You can stack up to a maximum of four units. Smaller units must be stacked above larger units.

To fit the clip:

1Fit the clip across the top of the unit, as shown in Figure 5 (picture 1).

2Align the fastening pieces over the slots found on each side of the unit.

3Push the clip down gently to secure it, ensuring that the fastening pieces snap into the slots on the unit.

24 CHAPTER 2: INSTALLING THE SWITCH

To fit another unit:

1Rest the second unit on the top of the clip and align it with the front of the unit below.

2Press down gently on the unit to secure in onto the clip, ensuring the fastening pieces fit into the slots on the unit below, as shown in Figure 5 (picture 2).
