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.
10/100/1000BASE-T
Ports
The Switch 4200G has 12, 24 or 48 auto-negotiating
10BASE-T/100BASE-TX ports configured as Auto MDIX (crossover). When
auto-negotiation is enabled these ports automatically operate in MDI or
MDIX mode as needed. These ports provide 10/100/1000 Mbps
full-duplex connections to other Gigabit Ethernet devices. Full-duplex
allows packets to be transmitted and received simultaneously which
effectively doubles the potential throughput of a link.
These ports require either straight-through or cross-over Category 5
cables with RJ-45 connectors at each end. The maximum UTP cable
length is 100 m (328 ft) over Category 5 cable.
The 10/100/1000BASE-T ports will auto-negotiate the appropriate speed.

1000BASE-X SFP Ports SFP (Small Form Factor Pluggable) ports support fiber Gigabit Ethernet
long-wave (LX), long-haul (LH70) and copper (T) SFP Transceivers in any
combination. This offers you the flexibility of using SFP transceivers to
provide connectivity between the Switch and remote 1000 Mbps
workgroups or to create a high capacity aggregated link backbone
connection.
The default state for these ports is auto-negotiation enabled, where the
speed, duplex and flow control modes are negotiated. As the speed and
duplex modes are fixed by the media type, only the flow control is
negotiated with the link partner. Alternatively, auto-negotiation can be
disabled (except 1000BASE-T which auto-negotiation is mandatory) and
the flow control setting can be manually configured.
Console Port The console port allows you to connect a terminal and perform remote or
local out-of-band management. As the console port on the Switch is an
RJ-45 port, you will need to connect an RJ-45 to DB9 converter cable to a
standard null modem cable in order to connect a terminal.
Unit Status Display The Status Display is a seven segment display visible on the front of the
Switch. The Status Display indicates switch status conditions such as the
unit number, POST test ID, and software upgrade information. In the
unlikely event of a hardware fault occurring, the Status Display may be
used to help diagnose the problem. For information on using the Status
Display for problem solving, see “Solving Problems Indicated by LEDs” on
page 54.
