STS-LM Stacker Link Module

Introduction

The SmartStack STS-LM Stacker Link Module is a single port

interface module, used to stack switches, that is installed into

the rear slot of the SmartStack Token Ring Switch. When two

SmartStack switches are connected through two STS-LM

modules, the switches can be combined to form one logical

switch. The STS-LM front panel is shown in Figure 1.

SmartStack STS-LM Package Contents

The STS-LM package contains the following items:

•

One STS-LM Stacker Link Module for the SmartStack

Token Ring Switch

•

One Stacker Link cable

•

One SmartStack STS-LM Installation Guide (this

document)

Installation

Use the following steps when installing the STS-LM module

in the SmartStack switch.

Note:

Stacker Link modules are

not

hot-swappable. Always

be sure that the power is off before installing or removing a

module. If the power is on, damage to the equipment may

result. Once the module is installed in the CrossFire 8600

Token-Ring Switch, external cables may be connected or

removed without having to remove power from the switch.

1. Disconnect power to the switch.

2. If a blank cover is over the stacker slot on the back panel,

remove it by unscrewing the two attachment screws.

3. To prevent possible static damage to the module, hold it by

its edges only. Be careful not to touch the top or bottom.

4. Slide the module into the slot evenly, taking care to line up

the edges with the guides.

5. Seat the module by pressing the front of the module with

your thumbs.

6. Secure the module to the chassis by tightening the thumb

(panel) screws at the left and right edges of the module’s

front panel. Do not overtighten the screws.

7. Return power to the switch.

SmartStack STS-LM Connectors and LEDs

The following tables describe the connectors and LEDs on the

STS-LM front panel.

Connecting the Stacker Link Cable

The proprietary 50-pin cable must be used to connect the

STS-LM in a stack.

The SmartStack switch can be configured in three different

ways to form a stack of switches:

•

Two SmartStack switches via two STS-LM modules

•

Up to five SmartStack switches via four STS-LM modules and

one STS-5SU Stacker Unit

•

Up to eight SmartStack switches via eight STS-LM modules

and one STS-8SU Stacker Unit

When inserting the cable connector, keep the connector

straight to minimize the risk of bent or damaged pins.

Working with a Stack

When the SmartStack switch powers up, it runs through a

series of diagnostics. Immediately after the diagnostics are

complete, the SmartStack switch enters the stack discovery

mode. The discovery mode is used to sense if the unit is cabled

to other SmartStack switch units. If the SmartStack switch is

connected to other units during the discovery mode, the

switches automatically combine to form a stack.

Each unit is assigned a box number. The switch with the lower

MAC address becomes Box 1, the switch with the higher

MAC address becomes Box 2 and so forth. When accessing

switch specific settings from a management console, you will

be prompted for a box number.

The switches in the stack combine certain configuration

parameters so that the stack as a unit uses one set of

parameters. These parameters are discussed below in “Inter-

box Parameters”.

The stack can now be managed as a single entity from a

management console or management application.

Inter-box Parameters

The SmartStack switches participating in the stack must

combine configuration information so that the stack as a whole

uses common parameters. One of the participating switches

becomes the provider of inter-box parameters.

If the switches have the same configuration information, the

switch that becomes Box 1 becomes the provider. If the

configuration information is different, a split-stack will be

formed and a warning message will be displayed on the

console screen. You will be requested to briefly press the

SysReq button on the switch that is to be the provider of inter-

box parameters. When you have selected the provider, the

other switch will replace its stack related configuration

parameters with those of the provider.

Connector Description

Stacker Port 50-pin SCSI-2 connector for proprietary

Stacker Link cable.

LED State Description

TX On Data is being transmitted to the

attached switch.

RX On Data is being received from the

attached switch.

ATTACH Off No connection has been established.

On A connection has been established.

Table 2. STS-LM LEDs

Checking the Installation

The SmartStack Token Ring Switch performs a diagnostic

self-test during the power on cycle. From a management

console, check that the switch lists the STS-LM port along

with the switch ports and that there are no error messages. The

STS-LM port will be listed as port 29.

If, after installation, there is poor system performance or the

STS-LM module does not work at all, remove the module and

check for any damaged or bent connector pins. You may need

a bright light to see inside the stacker slot to check for bent

pins. Also, verify that the module is set firmly in place.
