Introduction

This guide provides information about conﬁguring and managing basic switching features on the Nortel Ethernet Routing Switch 2500 Series.

This guide describes the features of the following Nortel switches.

•

Nortel Ethernet Routing Switch 2526T

• Nortel Ethernet Routing Switch 2526T-PWR

•

Nortel Ethernet Routing Switch 2550T

•

Nortel Ethernet Routing Switch 2550T-PWR

The term "Ethernet Routing Switch 2500 Series" is used in this document to describe the features common to the switches mentioned above.

A switch is referred to by its speciﬁc name while describing a feature exclusive to the switch.

The Ethernet Routing Switch 2500 Series operates in the Standalone Mode and Stacking Mode in this product release.

Before you begin

This guide is intended for network administrators who have the following background:

•

basic knowledge of networks, switching, Ethernet bridging, and IP routing

•

familiarity with networking concepts and terminology

•

basic knowledge of network topologies

braces ({}) Indicate required elements in syntax descriptions where

there is more than one option. You must choose only one of the options. Do not type the braces when entering the command.

Example: If the command syntax is

show ip {alerts|routes}, you must enter either show ip alerts or show ip routes, but not both.

brackets ([ ]) Indicate optional elements in syntax descriptions. Do

not type the brackets when entering the command.

Example: If the command syntax is show ip interfaces [-alerts], you can enter either show ip interfaces or show ip interfaces -alerts.

italic text Indicates variables in command syntax descriptions.

Also indicates new terms and book titles. Where a variable is two or more words, the words are connected by an underscore.

plain Courier text

Example: If the command syntax is

show at <valid_route>, valid_route is one variable and you substitute one

value for it. Indicates command syntax and system output, for

example, prompts and system messages.

The Console port is a DB-9, RS-232-D male serial port connector. You can use this connector to connect a management station, console, or terminal to the Ethernet Routing Switch 2500 Series by using a straight-through DB-9 to DB-9 standard serial port cable. You must use a VT100/ANSI-compatible terminal (for cursor control and to activate cursor and functions keys) to use the Console port.

The default settings of the Console port are:

• 9600 baud with eight data bits

•

one stop bit

•

no parity as the communications format

•

ﬂow control set to disabled

Gigabit Interface Converter

Small Form Factor Pluggable Gigabit Interface Converters are hot-swappable input and output enhancement components designed for use with Nortel products to allow Gigabit Ethernet ports to link with ﬁber optic networks.

SFP GBIC Support on the Ethernet Routing Switch 2500 Series

Small Form Factor Pluggable (SFP) transceivers are hot-swappable input/output enhancement components designed for use with Nortel products to allow Gigabit Ethernet ports to link with other Gigabit Ethernet ports over various media types.

The Ethernet Routing Switch 2500 Series supports the following SFPs:

•

1000Base-SX SFP GBIC (mini-GBIC, connector type: LC)

•

1000Base-SX SFP GBIC (mini-GBIC, connector type: MT-RJ)

•

1000Base-LX SFP GBIC (mini-GBIC, connector type: LC)

•

CWDM SFPs

For more information about the SFP GBICs see Installing Gigabit Interface Converters, SFPs, and CWDM SFP Gigabit Interface Converters (312865).

Port connectors

The Ethernet Routing Switch 2500 Series uses 10BASE-T/100BASE-TX RJ-45 (8-pin modular) port connectors.

The Ethernet Routing Switch 2500 Series uses autosensing ports designed to operate at 10 Mb/s (megabits per second) or at 100 Mb/s, depending on the connecting device. These ports support the IEEE 802.3u autonegotiation standard, which means that when a port is connected to another device that also supports the IEEE 802.3u standard, the two devices negotiate the best speed and duplex mode.

4.1 19 November 2007

Hardware components of the Ethernet Routing Switch 2500 Series 27

The 10BASE-T/100BASE-TX switch ports also support half- and full-duplex mode operation.

The 10BASE-T/100BASE-TX RJ-45 switch ports can connect to 10 Mb/s or 100 Mb/s Ethernet segments or nodes.

ATTENTION

Use only Category 5 copper Unshielded Twisted Pair (UTP) cable connections when connecting 10BASE-T/100BASE-TX ports.

Auto-MDI/MDI-X

The 10/100BASE-TX port connectors support auto-MDI/MDI-X. Typical MDI-X ports connect over straight-through cables to the Network

Interface Card (NIC) in a node or server, similar to a conventional Ethernet repeater hub. However, with the auto-MDI/MDI-X feature, you can still use straight-through cables while connecting to an Ethernet hub or switch.

The auto-MDI/MDI-X feature is dependent on the autonegotiation feature. If autonegotiation is enabled on a port, the auto-MDI/MDI-X feature is automatically enabled on the port as well. If autonegotiation is disabled on a port, then the port operates as a standard MDI-X port.

Power over Ethernet on Ethernet Routing Switch 2526T-PWR and 2550T-PWR

The Ethernet Routing Switch 2526T-PWR and 2550T-PWR provide IEEE

802.3af-compliant power over the PoE-labeled front-panel RJ-45 ports. The switches provide power discovery and power management on each port basis. You can use the PoE ports to provide power to network appliances, such as IP Phones, wireless access points, and video devices.

You can enable or disable power to individual ports. For information about conﬁguring PoE, see "Power over Ethernet for the Ethernet Routing Switch

2526T-PWR and 2550T-PWR" (page 157).
