16 CHAPTER 1: INTRODUCING THE SWITCH 4500 FAMILY
Two 1000Base-T SFP transceivers are included with these units. These SFP
transceivers can be inserted in any of the four SFP slots to provide copper
Gigabit connectivity. If you install these in the inactive ports, then you will
need to issue the undo shutdown command on those ports to make
them active.
SFP (Small Form Factor Pluggable, or mini-GBIC) 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.
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.
