Overview of the TokenSpeed Module

This chapter introduces the 8-port TokenSpeed module and covers the following
topics:

• A summary of module functions, capabilities, and features (starting on this
page)

Chapter 1

• A physical description of the module printed circuit board and the board in
relation to the Centillion switch chassis (see page

About the TokenSpeed Module

The 8-port TokenSpeed module inserts into one slot of a Centillion 100 or
Centillion 50 switch chassis to provide token ring ports and, optionally, an
integrated master control processor (MCP). This module replaces earlier module
versions that provided only four ports. The TokenSpeed module comes in the
following configurations:

• A TokenSpeed module with eight switched token ring ports with RJ-45
connectors for unshielded twisted pair (UTP) or shielded twisted pair (STP)
cable

• A TokenSpeed/MCP module with eight switched token ring ports with RJ-45
connectors for UTP/STP cable and a serial port implemented on a Mini DIN 8
connector

These modules offer identical functional features for token ring connectivity.
In addition to providing token ring connectivity, a Tok enSpeed/MCP module also
manages the Centillion switch. The MCP port can be used to connect a network
management station. One (and only one) MCP module is required for each
Centillion chassis; however, an ATMSpeed/MCP or EtherSpeed/MCP module
can also be used to meet this requirement.

This chapter provides information about typical uses of the TokenSpeed module
to improve network performance. The chapter includes information about the
following uses:

TokenSpeed Module Applications

• Giving a server a dedicated port (see this page)

• Segmenting a ring (see page

• Replacing a source route bridge or router (see page

• Concentrating rings into a router (see page

2-2)

Giving a Server a Dedicated Port

You can improve server response and increase throughput capacity by giving a
server a dedicated port on the TokenSpeed module.

Note: Giving a server a dedicated port on the TokenSpeed module need not

increase the source route hop count. You can maintain or even decrease the
source route hop count by assigning the server to the same virtual ring as its
communicating stations (refer to Using SpeedView 2.1 for Windows.)

To concentrate rings into a router , make sure virtual rings in the network are set up
in one of the following two ways:

• To segment a congested ring without using new router ports, be sure that all
stations previously connected to a single router port are in the same virtual
ring (refer to Using SpeedView 2.1 for Windows). The router will continue
to view the network the same way it did before the rings were segmented.

• To concentrate multiple, small ring segments into a router subnet and to free
router ports, be sure all segments are in the same virtual ring so that you can
group the entire virtual ring into a single router port. Be sure that the number
of devices in the virtual ring does not exceed the subnet size defined on the
router.

Using the 8-port TokenSpeed and TokenSpeed/MCP Switch Modules

Caution: Centillion modules use electronic components that are sensitive to

static electricity. Static discharge from your clothing or other items around
you, even at levels that do not create a spark, can cause damage. Take all
possible precautions to prevent static discharge damage when working with
printed circuit boards.

Keep each board in its protective conductive bag until you are ready to install
it. If possible, place all printed circuit boards on an antistatic mat and wear a
grounded antistatic wrist strap and leash to free yourself of static.

If you lack a grounded antistatic wrist strap and mat, be careful to stand in one
place where you work (so you do not generate static electricity by friction) and
to free yourself of static by touching the metal of a grounded chassis before
handling a printed circuit board.

Installing the TokenSpeed Module

You can insert or remove a TokenSpeed module from a switch chassis while the
power is on without interrupting service in the other installed modules. This
ability is referred to as “hot swapping.”

Note: A TokenSpeed module can be hot inserted into a switch chassis at any

time. However, before removing an active module from a switch chassis, you
must deactivate the module by either unplugging all port cables or disablin g all
ports on the module. For additional information, see “

Replacing a Module” on page 3-11.

To install and secure the module in the chassis, follow these steps:

1. Remove the filler panel.
a. Loosen the two captive retaining screws on a filler panel until they

pop free of the chassis frame.

Verifying the Installation

When the TokenSpeed module is installed and the cables are connected to the
ports, the module is ready for operation. All connected ports are enabled, unless
they have been disabled by SpeedView. Enabling and disabling TokenSpeed
module ports is described in Using SpeedView 2.1 for Windows.

You can verify the installation of a TokenSpeed module by looking at the LEDs
on the module while the module is operating and during the system startup
sequence. This section describes the TokenSpeed module LEDs and the LED
sequence that occurs when the module starts.

Removing and Replacing a Module

A TokenSpeed module can be hot inserted in a chassis at any time, but a
TokenSpeed/MCP module should not be removed from a functioning switch.
Installing a TokenSpeed/MCP module resets the switch and loads the default
configuration, thus interrupting network connectivity.

able 3-3 for default ring

If you are adding a module to an empty slot in an already functioning switch,
follow the instructions that begin on page

3-2. If you are replacing an installed

module, follow the instructions in the next two sections.
To remove or replace a TokenSpeed or TokenSpeed/MCP module, you need a

medium-size f lat-tip screwdriver to loosen and tighten the retaining screws on the
module.

If you suspect that a TokenSpeed module is malfunctioning, see Chapter

4,

“Troubleshooting the TokenSpeed Module,” before you replace the module.

Note: To minimize configuration conflicts, you should replace a module with

another identical module. If the new module is not identical to the module
previously in that slot, the new module remains inoperative until it is
reconfigured using SpeedView.

Replacing a TokenSpeed Module

You do not need to turn off the switch power before you replace a TokenSpeed
module that does not have an MCP.

To replace a TokenSpeed module, follow these steps:

1. Disable all ports on the module using SpeedView, or disconnect the cables

from each port.

Disabling the ports on a module is described in Using SpeedView 2.1 for
Windows.

2. Wait 45 seconds.

Waiting allows the system software to process the requests to disable the
ports.

Caution: If you remove a module without waiting 45 seconds after disabling

the ports, you must power cycle the Centillion switch chassis. When you turn
off the power on the Centillion switch chassis, you must w ait 15 to 20 seconds
before turning the power back on. The TokenSpeed modules begin switching
an additional 15 to 20 seconds after power is resumed.

The switch begins executing the loaded switch image and prompts you to
reset the switch.

12. Choose Reset to verify that the downloaded image is installed properly.

Troubleshooting the TokenSpeed Module

When the switch completes the reset and starts operating properly, you may
continue normal operation. If the reset is unsuccessful or an error indication
appears, repeat the entire procedure. If it fails again, call Bay Networks customer
support. Please be ready to provide the service representative with the information
listed on page

4-1.

TokenSpeed Module Startup Failure

Symptom: The switch startup process completes successfully, but the Activity
LED blinks continually.

To resolve the problem, follow these steps:

1. Check all modules in the chassis to make sure they are firmly seated and

that the retaining screws are tight.

2. Remove and reinsert the failing module.

If the problem persists, contact Bay Networks customer support. Please be ready
to provide the service representative with the information listed on page

4-1.

Port Insertion Problems

Symptom: The Act LED on a token ring port does not flash for a period of 15 to
20 seconds.

No flashing on the Act LED on a token ring port typically indicates port insertion
problems.

To resolve the problem, follow these steps:

1. Verify that the port is not operational by accessing the SpeedView

multicast frame transmit and receive count statistics (Mcst xmit and
Mcst rcv). Verify that the statistics are updating regularly over a period
of 15 to 20 seconds.

If the counts change, the token ring port is inserted and operating. If the port
is operating but the Activity LED stays dark, the LED may be damaged.

If the counts do not change, the token ring port is not inserted or enabled.
Proceed to the following steps to verify proper installation, configuration, and
connection for the port.

2. Verify that the cabling is correct.

See Appendix

B, “Cables,” for information about the token ring port types

and pin assignments for different connectors.

3. Using SpeedView, verify the following items:

• The appropriate port type is configured: Station, Hub, Bay/SNPX RO,
RI–other, or RO–other.

For more information about setting port types, see “

Token Ring

Connections” on page 3-6.

• The port is enabled.

4-4 893-01019-A

TKNSPD.BK Page 5 Thursday, July 17, 1997 11:43 AM

• Port speed and speed sensing are configured appropriately.
– If the port speed is not set to Auto, and Speed Sense is disabled,

the port is forced to operate at a particular speed. Verify that the
configured speed matches the actual speed of the ring.

– If Speed Sense is enabled, be sure that at least one device on the

connected ring is not set to Speed Sense.

– If the switch is connected to an intelligent hub that has automatic

speed sensing, such as a Bay Networks hub, configure a specific
speed for the port on the TokenSpeed module and disable the
Speed Sense option.

• The ring number assigned to this port does not conflict with other ring
numbers in the network.

Troubleshooting the TokenSpeed Module

If the ring parameter server tells the port a different ring number from the
number that is configured, the port will deinsert.

4. Disable the port; then enable it again.

5. If the port still fails to insert, try inserting the port into another ring

segment.

If the second port inserts successfully, check the status of the first ring.
If the second port fails to insert into the other ring, contact Bay Networks

customer support. Please be ready to provide the service representative with
the information listed on page 4-1.
