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 5500 has 24 or 48 auto-negotiating 10BASE-T/100BASE-TX

ports configured as Auto MDIX (cross-over). These ports automatically

provide the appropriate connection. Alternatively, you can manually set

these ports to 10BASE-T half duplex, 10BASE-T full duplex, 100BASE-TX

half duplex or 100BASE-TX full duplex. The maximum segment length is

100 m (328 ft) over Category 5 twisted pair cable.

16 CHAPTER 1: INTRODUCING THE SUPERSTACK 4 SWITCH 5500 FAMILY

1000BASE-X SFP Ports SFP (Small Form Factor Pluggable) ports support fiber Gigabit Ethernet

short-wave (SX), 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-neogtiation 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 LED The Unit LED is a seven segment display visible on the front of the Switch.

The Unit LED can be used to indicate the unit number in a fabric, POST

test ID and software upgrade information. In the unlikely event of a

hardware fault occurring, the Unit LED may be used to help diagnose the

problem. For information on using the Unit LED for problem solving, see

“

Solving Problems Indicated by LEDs” on page 62

LEDs Table 4 lists LEDs visible on the front of the Switch, and how to read their

status. For information on using the LEDs for problem solving, see

“

Solving Problems Indicated by LEDs” on page 62.
