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. In all cases, the attached device must be within 328 feet (100 meters).

UNIs and NNIs are supported on the Cisco ME switch. UNIs are typically connected to a host, such as a PC or a Cisco IP Phone. By default, the 10/100 ports on the Cisco ME switch are configured as UNIs.

A port can be reconfigured from UNI to NNI and the reverse. When a port is reconfigured as another interface type, it inherits all the characteristics of that interface type. All ports on the Cisco ME switch are either UNI or NNI at any time.

For information on configuring interfaces, see the software configuration guide.

SFP Module Slots

The SFP module slots support the SFP modules that are supported on the Cisco ME switch. These are listed in the “SFP Modules” section on page 1-4.

By default, the SFP module ports on the Cisco ME switch are configured as NNIs. A port can be reconfigured from UNI to NNI and the reverse, but only four ports on the switch can be NNIs at the same time.

For more information on configuring interfaces, see the software configuration guide.

SFP Modules

The Cisco ME switch uses Gigabit Ethernet SFP modules to establish fiber-optic and 1000BASE-T connections. These transceiver modules are field-replaceable, providing the uplink interfaces when inserted in an SFP module slot. You can use the SFP modules for Gigabit uplink connections to other switches. You use fiber-optic cables with LC or MT-RJ connectors to connect to a fiber-optic SFP module. You use Category 5 cable with RJ-45 connectors to connect to a copper SFP module.

The Cisco ME switch supports these Cisco SFP modules:

100BASE-BX

100BASE-FX

100BASE-LX

1000BASE-BX

1000BASE-LX/LH

1000BASE-SX

1000BASE-T

1000BASE-ZX

CWDM
