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.
