STS-5SU Internal Stacker Unit

Introduction

The SmartStack STS-5SU Internal Stacker Unit is a 4-port
interf ace modul e th a t is in stalled in to th e r ear slot of an y
SmartStack Token Ring Switch. When five SmartStack
switches are connected together through the SmartStack STS­5SU module, the switches combine to form one logical switch.
The SmartStack STS-5SU front panel is shown in Figure 1.

SmartStack STS-5SU Package Contents

The SmartStack STS-5SU package contain s the following
items:

•

One SmartStack STS-5SU Internal Stacker Unit for the
Cabletron SmartStack Token Ring Switch

•

One SmartStack STS-5SU Ins tallation Guide (thi s
document)

Installation

Use the fo ll owing steps w h en in stalling the Sm ar t S ta ck S TS ­5SU module in the SmartStack switch.

Note:

SmartStack STS-5 SU 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
switch, external cables may be connected or rem oved without
having to remove po wer from the switch.

1. Disconnect power to the switch.

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

remove it by unscrewing the two attachm ent screws.

3. To pr e v ent p os sible st atic da mage t o t he module, hol d it by

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

4. Slide the mod ule int o t he slot e ven ly, ta king ca re 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 chass is by tightening the thumb
(panel) screws a t the l eft and righ t e dges of the fr ont panel .
Do not overtighten the screws.

7. Return power to the switch.

SmartStack STS-5SU Connectors and LEDs

Connecting the Stacker Link Cable

A proprietary 50-pin cable must be use d to connect ports on
the SmartStack STS - 5SU module with up to four Smar tStack
STS-LM Link Modules in other SmartStack switches. Five
switches can be combined in this way to form a very cost­effectiv e stack of switches.

Note:

The SmartStack STS-5SU Internal Stacker Unit must
only be connected to Smart Stack STS-LM Li nk Modules. You
cannot create a stack by connecting SmartStack STS-5SU
modules together.

When inserting the cable connector, keep the c onnector
straight to minimize the ris k of bent or damaged pins.

W orking With a Stack

When the SmartStack switch powers up, it runs through a
series of diagnostics. I mmedi ately 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 units. If the SmartStack switch through a SmartStack
STS-5SU 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 swit ch with the lowe r
MAC address becomes Box 1, the swi tch with the higher
MAC address becomes Box 2 and so forth. When accessing
switch specific settings from a management consol e, you will
be prompted for a box number.

The switches in the stack combi ne certain configuration
parameters so that th e st ack as a u ni t uses one set of
parameters. These parameters are discussed below in “Inter­Box Parameters”.

The stack can now be managed as a single enti ty from a
management console or management application.

Inter-Box Parameters

The SmartStac k switches participating in the stack must
combine configuratio n information so that the s tack 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 t o be the provider of inter­box parameters. When you have sel ec ted the provider, the
other switch will replace its stack related configura tion
parameters with those of the provider.

Table 3 lists the inter-b ox parameters.

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 SmartStack STS-5SU
port along with the switch ports and that there are no error
messages. The SmartStack STS-5SU port will be listed as port

29.
If, after installation, there is poor system performance or the

SmartStack STS-5SU modul e does not work a t all, r emove the
module and check for any damaged or bent connec tor pins.
You may need a bright light to see inside the stacker slot to
check for bent pins. Also, veri fy that the module is set firmly
in place.
