About the Switch

4200G

The Switch 4200G Family are mixed media devices which consist of:

■ 12, 24 or 48 10/100/1000BASE-T ports

■ Four 1000BASE-X SFP ports

■ One option module slot for a 10 Gigabit Ethernet port module on the

Switch 4200G 12-Port. Requires an optional XFP.

The Switch 4200G Family provides high-performance workgroups with a

backbone to server connection. You can also add the Switch 4200G

Family to any SuperStack

®

system as your network grows.

For information about using the software features of the Switch, refer to

the “Command Reference Guide” and the “Configuration Guide” on the

CD-ROM that accompanies the Switch.

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.
