INTRODUCING THE

OFFICECONNECT MANAGED

SWITCH 9 AND SWITCH 9FX

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 9FX

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.

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.

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

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.
