SSIM-H2-02 Fast Ethernet - Translational Switch SmartStack Interface Module Installation and User Guide Introduction

1. Introduction

The Cabletron Systems SmartStack SSIM-H2-02 2-port Translational Switch

SSIM (SmartStack SSIM-H2-02) provides connectivity to 10/100 Mbps Fast

Ethernet for the SmartStack STS16-20RM Token Ring Switch. Designed for high

performance and low latency, the SmartStack SSIM-H2-02 seamlessly integrates

legacy Token Ring networks and Fast Ethernet backbones.

➽Note: References to SmartStack STS16-20RM are also applicable to SmartStack

STS16-20FRM.

The module mounts in one of the two front panel expansion module slots on the

SmartStack STS16-20RM switch.

Figure 1. SSIM-H2-02 Switch SmartStack Interface Module

The SSIM-H2-02 conforms to the IEEE standard 802.3U for 100 Mbps Fast

Ethernet 100BASE-TX.

A Translational Switch (TS) port can connect to a standard Fast Ethernet adapter or

it can act as a trunk port and carry traffic from all of the 63 VLANs it is possible to

configure inthe switch. This is achieved usingstandard IEEE 802.1QVLAN frame

tagging. For each VLAN, a virtual port is created which behaves much like an

ordinary Ethernet port.

The module supports all of the switching modes implemented in the switch. Eight

LEDs on the front panel indicate the overall operationalstate of the module and the

two ports. Configuration and detailed status information is available from the

switch console or from the graphical management application.
