1. Introduction
Overview
ESB26 is an integrated Ethernet switch based on DX200 hardware platform. The ESB26
features a total of 26 Ethernet ports of types and placements as follows:
Port Placement Connector Traffic
20 full duplex 10/100Base
T/TX Ethernet ports
back panel AMP 2mm Z-pack
connectors compatible
downlink
2full duplex 10/100Base
T/TX Ethernet ports
front panel RJ45 downlink/uplink
21000Base-T ports front panel RJ45 downlink/uplink
21000Base-SX ports front panel LC uplink
ESB26 contains also one RS-232 interface (RJ45) on the front panel for management
purposes.
The two 1000Base-T ports support all the 10/100/1000 Mbit/s link speeds. Speed mixing is
supported, too, e.g. it is possible to use one of the 1000Base-T ports in gigabit mode while the
other runs in 100Mbit mode.
The intended use of the ESB26 is to collect the Ethernet links of different computer units and
preprocessor units of DX200-based network elements, and allow access to them from the
upper levels. The ESB26 can be used in all M98F DX200 based network elements. The
ESB26 can be assembled into a place of ESB20/ESB20-A by using the existing cabling.
NOTE
The ESB26 is designed to operate in forced cooling M98F only.
The two graphics below represent two examples of operational environments for the ESB26.
As presented, the ESB26s are used to collect traffic from/to different computer units and
preprocessor units and forward it towards 3rd party L3 switches. It is important to note that
VLAN-technology is used in order to divide the different units into several broadcast
domains. It must also be noted that redundant paths do exists and Rapid STP (as according to
IEEE 802.1w) is used in order to avoid loops.

The switch is managed via BiNOSCommand Language Interface (CLI) commands typed in
by the user by either of the following means:
•By direct connection, through a VT-100 compatible terminal connected to the
console port on the unit’s front panel;
•Remotely, using telnet over a TCP/IP communication network.

Hot-Swap
The card can be inserted and removed while power is applied to the IPA2800 chassis. Before
removing the card, press the Reset button twice within two seconds. This will disconnect
power from the card for 20 seconds. The LED will turn off, indicating that the card can be
safely removed.

2. Getting Started
Overview
ESB26 installation consists of inserting the card into the appropriate slot in the system,
turning the unit power on, and setting the IP Address in order to enable remote management.
All other management procedures may be performed remotely via Terminal Interface
management applications that are integrated into the unit.
This chapter describes how to install the unit, perform initial setup, use Terminal Interface
management applications, and how to perform basic switch operations.
Unpacking
After unpacking:
•Verify that the ESB26 unit has not been damaged during shipment.
•It is recommended that you keep the shipping package until the unit has been
installed and verified as being fully operational. As all electronic devices with
static sensitive components, ESB26 should be handled with care.

Using the CLI to Configure the Switch
The configuration program uses a CLI (Command Line Interface) that enables you to start
using the switch quickly and without extensive background knowledge. It does this by
prompting you for the information required to perform basic configuration procedures.
Using the CLI, you will be able to do the following:
• Establish host names and interfaces
• Enable transparent Ethernet bridging
• Configure Layer 2 switch protocols (GVRP, GMRP, Spanning Tree, etc.)
• Configure VLANs
System parameters are stored in a non-volatile memory. They have to be set up only once
during initial setup.
Getting Started with the CLI
Configuration of the switch is done by connecting a VT-100 (or compatible terminal) to the
card RJ-45 (Console) connector.
