INTRODUCING THE |
OFFICECONNECT MANAGED |
SWITCH 9 AND SWITCH 9 FX
This chapter contains introductory information about the Switch 9 and Switch 9 FX and how they can be used in your network. It covers summaries of hardware and software features and also the following topics:
■About the Switch
■Switch — Front View Detail
■Switch — Rear View Detail
■Default Settings
12 CHAPTER 1: INTRODUCING THE OFFICECONNECT MANAGED SWITCH 9 AND SWITCH 9 FX
■ 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

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.
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.

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.
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.
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.

Choosing a Suitable |
The Switch is suited for use on a desktop, either free standing, stacked |
|
Site |
together with other units using the stacking clip, or mounted on a wall. |
|
|
Alternatively, the Switch can be placed in a wiring closet or equipment |
|
|
room, as an aggregator for other Hubs and Switches. A stacking kit |
|
|
containing one mounting clip is supplied with the Switch. |
CAUTION: Ensure that the ventilation holes are not obstructed.
When deciding where to position the Switch, ensure that:
■Cabling is located away from:
■sources of electrical noise such as radios, transmitters and broadband amplifiers.
■power lines and fluorescent lighting fixtures
■The Switch is accessible and cables can be connected easily.
■Water or moisture cannot enter the case of the Switch.
■Air flow is not restricted around the Switch or through the vents in the side of the Switch. 3Com recommends that you provide a minimum of 25mm (1in.) clearance.
■ Air temperature around the Switch does not exceed 50 °C (122 °F).
If the Switch is stacked with other OfficeConnect units its local air temperature may be greater than room ambient temperature.
■The air is as free from dust as possible.
■The unit is installed in a clean, air conditioned environment.
■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).

Wall-mounting |
There are two slots on the underside of the Switch that can be used for |
|
wall mounting. The Switch must be mounted with the LEDs facing |
|
upwards. |
|
When wall mounting the unit, ensure it is within reach of the power |
|
outlet. |
|
When wall mounting the unit, ensure that the rubber feet are not fixed. |
Mounting |
To wall mount the unit on a cement wall, follow these instructions: |
Instructions for |
|
Cement Walls |
|
1Make two holes 150 mm (5.9 in.) apart and insert two nylon or similar screw anchors that are suitable for the wall construction.
2Fix two suitable screws into the anchors, leaving their heads 3 mm (0.12 in.) clear of the wall surface. The screws should be at least 30 mm (1.2 in.) long.
3Remove any connections from the Switch and locate it over the screw heads. When in line, gently push the Switch on to the wall and move downwards to secure.
