C H A P T E R 1 Product Overview The Cisco Metro Ethernet (ME) 2400 Ethernet Access switch—also referred to as the switch—is an Ethernet access switch to which you can connect other network devices such as routers, other switches, a home access gateway (HAG), or a computer. This chapter provides a functional overview of the Cisco ME switch.
Chapter 1 Product Overview Front Panel Description – 100BASE-LX – 1000BASE-BX – 1000BASE-LX/LH – 1000BASE-SX – 1000BASE-T – 1000BASE-ZX – Coarse wavelength-division multiplexing (CWDM) Note When installed in Cisco ME switches, 1000BASE-T SFP modules can operate at 10, 100, or 1000 Mbps in full-duplex mode or at 10 or 100 Mbps in half-duplex mode. Note By default, the SFP module ports on the Cisco ME switch are configured as network node interfaces (NNIs).
Chapter 1 Product Overview Front Panel Description Front Panel Descriptions The 10/100 Fast Ethernet ports on the switch are grouped in pairs. The first member of the pair (port 1) is above the second member (port 2) on the left. Port 3 is above port 4, and so on, as shown in Figure 1-1 (the Cisco ME AC switch) and Figure 1-2 (the Cisco ME DC switch). The SFP module slots are numbered 1 and 2. Cisco ME 2400 AC Ethernet Access Switch Front Panel 1 SYSTEM 2 3 1X RATING 100 1A-0.
Chapter 1 Product Overview Front Panel Description 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.
Chapter 1 Product Overview Front Panel Description SFP Module Patch Cable The Cisco ME switch supports the SFP module patch cable, a 1/2 meter, copper, passive cable with SFP module connectors at each end (see Figure 1-3). The patch cable can connect two Cisco ME switches in a cascaded configuration. SFP Module Patch Cable 126809 Figure 1-3 See “Inserting and Removing the SFP Module Patch Cable” section on page 2-21 for more information about using the SFP module patch cable.
