Chapter 1 Product Overview
Front Panel Description
The 10/100/1000 ports on the Catalyst 3560G-48TS switch are grouped in pairs. The first member of the
pair (port 1) is above the second member (port 2) on the left, as shown in Figure 1-10. Port 3 is above
port 4, and so on. The SFP module slots are numbered 49 to 52.

10/100 and 10/100/1000 Ports
• You can set the 10/100 ports to operate in any combination of half duplex, full duplex, 10 Mb/s, or
100 Mb/s. You can set the 10/100/1000 ports to operate at 10 or 100 Mb/s in half or full duplex or
at 1000 Mb/s in full duplex.
• You can set both the 10/100 and the 10/100/1000 ports for speed and duplex autonegotiation, in
compliance with IEEE 802.3ab. (The default setting is autonegotiate.)
• You can configure duplex mode to half, full, or autonegotiate on Gigabit Ethernet interfaces if the
speed is set to 10 or 100 Mb/s. You cannot configure half-duplex mode on Gigabit Ethernet
interfaces if the interface speed is 1000 Mb/s.
• When set for autonegotiation, the port senses the speed and duplex settings of the attached device
and advertises its own capabilities. If the connected device also supports autonegotiation, the switch
port negotiates the best connection (the fastest line speed that both devices support and full-duplex
transmission if the attached device supports it) and configures itself accordingly. In all cases, the
attached device must be within 328 feet (100 meters).
Warning
Voltages that present a shock hazard may exist on Power over Ethernet (PoE) circuits if
interconnections are made using uninsulated exposed metal contacts, conductors, or terminals.
Avoid using such interconnection methods, unless the exposed metal parts are located within a
restricted access location and users and service people who are authorized within the restricted
access location are made aware of the hazard. A restricted access area can be accessed only through
the use of a special tool, lock and key or other means of security.
Statement 1072
• 100BASE-TX and 1000BASE-T traffic requires Category 5 cable. 10BASE-T traffic can use
Category 3 or Category 4 cables.
