Installing the CoreBuilder 7000 Family ATM Switch
The two slots just under the power supply contain switching modules,
one slot for the active switching module and one slot for the redundant
switching module.
The switching module is the core switching engine of the CoreBuilder
7000 family ATM switch, controlling and monitoring passive backplane
and ATM activity. The switching module has a control port for connection
to a terminal, a management port for connection to a network
management station, and a service port for use by 3Com technicians.
The next four slots contain interface modules. These can be of many
different types; some are shown in the figure (see the
Family ATM Switches User Guide
for details).

The CoreBuilder 7000 family ATM switch is designed to meet the
requirements of environments where network interruptions cannot be
tolerated. The CoreBuilder 7000 family ATM switch platform has a fully
redundant design, with dual load-sharing power supplies and redundant
switching engines. All CoreBuilder 7000 family interface cards and
switching engines are hot swappable to ensure continuous operation
during configuration and servicing.
For information about determining the required power supply for various
CoreBuilder 7000 family ATM switch installations and providing
redundancy for various power loads see “Redundant Power Supply” on
page 7-1.
For information about using the redundant switching module see
“Redundant Switching Module” on page 7-9.
In addition to hardware redundancy, the CoreBuilder 7000 family ATM
switch also provides redundant LANE services which are managed by the
Transcend Network Management System. Each switch contains a
complete set of LES and LECS functionality. In case of failure, LANE
services can be transferred to another CoreBuilder 7000 family ATM
switch elsewhere in the network.

Safety Precautions
When handling replacement parts, 3Com recommends that you always
use a wrist strap connected to a proper ground. This helps prevent the
module from being damaged by electrostatic discharge. Additionally,
when not in use, the module should be stored in an antistatic bag.
If the system is powered on when you are replacing a module, do not
insert any metal objects, such as a screwdriver or a finger with jewelry, in
the open slot. This could cause burns or other bodily harm, as well as
system damage.
Vorsichtsmaßnahmen
Mesures de sécurité
Wenn Sie Ersatzteile handhaben, benutzen Sie immer ein Band am
Handgelenk, daß gut geerdet ist. Das hilft vermeiden, daß das Ersatzteil
durch elektrostatische Entladung beschädigt wird. Darüber hinaus sollte
ein Modul, wenn nicht benutzt, in einem antistatischen Beutel
aufbewahrt werden.
Steht das System unter Strom, wenn sie ein Modul installieren oder
auswechseln, führen Sie keine Metallgegenstände, wie einen
Schraubenzieher oder einen Finger mit Schmuck in den offenen Schlitz
ein. Das könnte zu Verbrennungen oder anderen Körperschäden führen,
sowie auch zu Schäden am System.
Lors de la manipulation des pièces de rechange, 3 Com recommande de
toujours utiliser une bande attachée au poignet et reliée à la terre. Cela
aidera à éviter que la pièce ne soit endommagée par une décharge
électrostatique. De plus, lorsqu'il n'est pas utilisé, le module doit être
conservé dans un emballage antistatique.
Si le système est alimenté lors de l'installation ou du remplacement d'un
module, ne jamais insérer d'objet métallique tel qu'un tourne-vis ou un
doigt portant un bijou dans la fente. Cela est susceptible de provoquer
brûlures ou autres dommages corporels, et d'endommager le système.

Installing a Power
Supply Module
The CoreBuilder 7000 family ATM switch provides a dual load-sharing
power supply capability where the second unit can serve as a redundant
power supply. For more information, see “Redundant Power Supply” on
page 7-1.
For certain combinations of installed interface cards, the second power
supply cannot be used as a redundant supply (see “Providing Redundancy
for Various Power Loads” on page 7-6).
This section discusses the following topics:
Installing a Power Supply Module
Replacing a Redundant Power Supply Module
To install a power supply module:
Orient the module so that its sides enter the guides on either side of the
1
chassis slot.
Slide the module into the chassis until the face panel is flush with the
2
enclosure.
Secure the screws on either side of the front panel.
3
If a redundant power supply is not installed in the second power supply
4
slot, cover the slot with a blank panel for safety.
Replacing a
Redundant Power
Supply Module
This section describes how to replace a redundant power supply module.
You can replace the redundant power supply without having to turn off
the system (hot-swap). For more information on the operation of the
redundant power supply module, see “Redundant Power Supply” on
page 7-1.
To replace a redundant power supply module:
Disconnect the power cord from the power supply.
1
Loosen the screws at the extreme right and left of the power supply, near
2
the handles (refer to Figure 4-1).
Grasp the handles of the redundant power supply you want to replace

Setting up Switch
Module Redundancy
This section describes procedures for installing and setting up both a
main and redundant switch module together.
Two different setup procedures are described. The first procedure covers
setting up the main and redundant switch module hardware redundancy
without setting up LANE redundancy. This procedure only requires
operating the Local Management Application (LMA). The LMA is
described in the CoreBuilder 7000 Family ATM Switch User Guide. The
second procedure sets up the main and redundant switch module
hardware redundancy as well as LANE redundancy. It requires both the
LMA and the Transcend Enterprise Manager.
There are two situations where you would use the procedures of this
section:
The initial installation of main and redundant cards.
1
The main card in the first slot has failed and the redundant card in the
2
second slot has taken over as the main card. The failed card in the first
slot has been replaced by a new card and this new card is now the
redundant one.

Setting up Switch
Module Redundancy
and LANE
Redundancy
This section presents a procedure for setting up both switch module
hardware redundancy and LANE redundancy in the same session. Both
the LMA and the Transcend Enterprise Manager are used.
General Description of the Procedure
The following is a general description of the procedure for orientation
purposes only. When you perform the procedure, use the detailed steps
in the following sections.
Install both switches in chassis and run RESETCFG.BAT on each one.
1
Connect Ethernet ports of each switch module and install at least one
interface card in the chassis.
Configure the first switch using the Integrated Fast Setup of the LMA and
2
do not reboot the switch in the Integrated Fast Setup.
Reboot the switch after one minute using the LMA menu.
3
Answer “no” to the prompt “Erase the setup parameters?” and use the
4
LMA to check that all configuration parameters (i.e., database, IP, NNI
etc.) have passed successfully to the second switch module.
Configure LANE redundancy in the first switch using the Transcend
5
Backbone and Services Setup window and close the window when
finished.
Reboot the switch after one minute
6
Configure LANE redundancy in the second switch module using the
7
Transcend Backbone and Services Setup window and close the window
when finished.
After one minute use the MIB browser to check the LECS order list and
8
the Backbone and Services Setup window to check the LECS database.
Reboot the box.
9
Check the second switch using the MIB browser to check the LECS order
10
list and the Backbone and Services Setup window to check the LECS
database.
Switch Module
Preparatory Steps
Carry out the following preparatory steps.
Install main and redundant switch modules in the switch module slot 1
1
and slot 2 respectively (see “Installing a Switch Module” on page 4-5). Do
not run the Integrated Fast Setup yet.
Each time the switch is rebooted during this procedure the cards change
roles. The main card becomes the redundant card and vice versa. The
main card can always be identified by its ACT LED flashing once every
two seconds. The ACT LED of the redundant card flashes at a lower rate.
Verify that at least one interface card of any type is installed in the
2
CoreBuilder chassis in any interface card slots 3-6. Data is transferred
between switch modules via a communications chip on an interface card.
Verify that the Ethernet management ports in both switches are
3
connected to the NMS station. They can either be connected through a
hub to the NMS station or through an Ethernet interface card in the same
chassis, such as the CoreBuilder 7400 High Density Ethernet/ATM
interface card, to the NMS station.
4-9
During the procedure you will need to verify connectivity between the
NMS station and the switch by pinging the switch module from the NMS
station.
Connectivity between the switch module and its attached devices is
established by an RARP transmitted by the switch module when it boots.
The RARP causes a device to learn the MAC address of the switch
module. However, there are certain devices, for example, a Solaris station,
which will not learn a new MAC address for an IP when one already
exists. If you are using one of these devices as an NMS station, and you
are unable to ping the switch module, try erasing the switch module’s
MAC address from the device’s ARP table and ping again.
Verify that the RS-232 terminal line is connected to the console port on
4
the main switch module.
Procedure Execution
Reset the configuration of both switch modules by executing the
1
RESETCFG.BAT file supplied with your software.
Do not use the LMA menu (1) SYS / (2) RES to reset the switch module
configuration.
4-10

a
system in Load Mode: Load.
Reboot the switch using the LMA menu command: (1) SYS / (7) RBO.
b
The switch will reboot in debug mode.

c
module.
From a DOS window on the LMA terminal execute

where “com” is the communications port you are using and “speed”
is 115200 for a CoreBuilder 7000HD switch module and 57600 for a
CoreBuilder 7000 switch module.
Transfer the RS-232 cable to the service port of the redundant switch
e
module.
Repeat step d)
f
Transfer the RS-232 cable to the console port of the main switch
g
module.
Switch Module Redundancy Setup
Set up the main switch module using the Integrated Fast Setup (see
2
“Integrated Fast Setup” on page 6-3). Do not reboot the switch from the
Integrated Fast Setup procedure (answer “no” to the prompt).
The main menu appears.
Wait for one minute to allow the configuration data to transfer from the
3
main switch module to the redundant switch module.
Reboot the switch using the LMA menu sequence: (1) SYS / (7) RBO. This
4
causes the configuration data to be recorded in flash memory and also
causes the redundant switch module to become the main switch module.
After the switch reboots, answer “no” to the prompt: “Do you wish to
5
erase the setup parameters”.
Run the Integrated Fast Setup procedure as in step 2) to verify that the
6
setup parameters have been transferred correctly to the second switch
(the Integrated Fast Setup procedure now displays the setup parameters
resident in the second switch module). Press Enter repeatedly to verify
these parameters; do not enter new values.
Switch Module
Verify that the ELAN names in the LECS database are identical in both
7
switch modules. Use menu item (2) LEM/(1) LCS/(5) LNT to check that the
LECS database of the second switch includes the ELAN name of the first
switch. For example, Elan6666_0 - Elan6666_15
LANE Redundancy Setup
Verify connectivity between the switch module and the NMS station by
8
pinging the switch module from the NMS station.
Load the Transcend application and open the Wizard Tool from the
9
ATMvLAN tool bar
Open the Backbone and Services Window.
10
Configure the LECS order as desired and press the Apply button.
11
Configure the LECS database. Add all the primary and redundant ELAN
12
names desired to the LECS database and press Apply. Make a list of the
ELAN names you have selected. You will need them for setting up the
other switch module.
When finished, close the Backbone and Services window.
13
4-11
Wait one minute to allow the LECS order database to transfer to the
14
other switch module.
The LECS ELAN database does not transfer automatically.
Reboot the switch using the LMA menu sequence:
15
(1) SYS / (7) RBO.
The purpose of this step is to make the first switch module active in order
to set up the LANE services there.
After the first switch boots, check its connectivity with the NMS station as
16
in step 8).
Perform steps 10) and 12) using the same list of ELANs.
17
Wait one minute.
18
Verifying LANE Redundancy Setup
Use the MIB browser under the Transcend tools menu and browse
19

To replace individual daughter cards, or to replace the entire interface
module:
1 Disconnect the cables from the card's ports. Ensure that there is a record
of where the cables are attached so that you can correctly re-connect
them to the new card.
2 Loosen the screws at the extreme right and left of the card, near the
insert/eject handles.
3 Grasp the insert/eject handles of the card you want to replace and push
them outward. This ejects the card. You may have to apply considerable
force to the handles. You will hear a “click” to indicate that the
connections have separated, and the card will slide slightly forward out of
the CoreBuilder chassis.
4 If you are replacing the entire interface card, remove the new card from
its antistatic bag. Place the old card in the antistatic bag and set it aside in
a safe place.
To replace the fan tray:
1 Loosen the screws at the top and bottom of the fan tray.
2 Pull the fan tray out of the chassis.
3 Remove the new fan tray from its antistatic bag. Place the old fan tray in
the antistatic bag and set it aside in a safe place.

4 Orient the fan tray so its labelling is upright.
5 Insert the new fan tray into the chassis by placing it between the guides
of the slot and sliding it until it stops.
6 Tighten the fan tray’s securing screws.

To connect a CoreBuilder 7000 family ATM switch port to another
CoreBuilder unit, to a LinkSwitch 2700 ATMLink adapter, or to any device
with an ATM optical interface:
1 Prepare an optical cable (Tx Rx). You may want to mark the ends of the
cable so you can identify them.
2 Snap the cable into a CoreBuilder 7000 family ATM switch port in one of
the interface modules.
3 Snap the other end of the cable into the selected optical interface of the
other ATM device. Make sure that each wire connects to Rx on one end
and Tx on the other.
4 Repeat steps 1-3 for all ATM port connections to the CoreBuilder.
Perform steps 1-4 above when connecting a DS-3 coax cable set (Rx and
Tx).

Connecting the
Control Terminal
Connecting to the
Ethernet Port
The CoreBuilder 7000 family ATM switch can be configured via the LMA
using the Administration Console terminal (VT100) or terminal emulator
(Windows). To connect a terminal to the CoreBuilder 7000 family ATM
switch control port:
1 Prepare an RS-232 shielded cable (9 pin-to-9 pin or 9 pin-to-25 pin, as
dictated by the terminal you wish to use).
2 Configure the terminal: 19200 baud, 8 data bits, 1 stop bit, no parity,
xon/xoff flow control.
3 Push the DCE side of the cable onto the Control port of the switch
module and screw it into place.
4 Connect the other end of the cable to the terminal.
In case you have installed a redundant switch unit, it is sufficient to
connect the RS-232 line to either the active switch control port or to the
redundant switch control port.
The Ethernet port is used for connecting directly to a Transcend NMS
terminal for management purposes.
In case you have installed a redundant switch module, its Ethernet port
must also be connected directly to the Transcend NMS terminal.
Connecting to the
Power Source
Another way of connecting the Ethernet port to an out-of-band Ethernet
network is to connect it to a CoreBuilder 7200 Ethernet/ATM Interface
Card or a CB7400 High Density Ethernet/ATM Interface Card installed in
the same chassis.
This section describes how to connect the CoreBuilder 7000 family ATM
switch to the power source.

indicate the current system state of the CoreBuilder unit and its
components. Front panel LEDs can be extremely useful in determining the
cause of specific problems.
The system state in which the CoreBuilder 7000 unit is currently
operating is displayed by the switching module system status LEDs.
Referring to Figure 5-1, these are the three LEDs: PWR, FAIL, and ACT(ive)
on the left side of the LED panel. Table 5-1 shows the correlation
between the current system state and SYS LEDs display. For example,
during normal operation the PWR LED is on, the FAIL LED is off and the
ACT LED is flashing. The LEDs on the right side of the panel indicate the

Apply electrical power to the system by inserting the power cord in the
power supply unit. The power supply indicator lights and the CoreBuilder
7000 family ATM switch automatically runs diagnostic software. This
software verifies that every component in the system is fully functional
before the system becomes active on the network. Diagnostics should
take sixty seconds or less.
If any component fails power-on diagnostics, the system either fails to
power on or it keeps faulty modules off-line. Once the system comes up,
you can check to see which modules, if any, have failed diagnostics by
checking the LED panels; in-depth information is available by viewing the
system configuration screens on the administration console.

Setup
This section describes the Integrated Fast Setup procedure and contains
the following topics:

Navigation Aids
Integrated Fast Setup Operation
You use the Integrated Fast Setup procedure to configure the minimum
set of parameters needed to enable the CoreBuilder 7000 family ATM
switch and its attached devices to function in the network.
With this procedure you can configure both the CoreBuilder 7000 family
ATM switch card and all CoreBuilder 7X00 interface cards installed in it in
one session.
In certain cases you will need to use the Fast Setup procedure of
individual CoreBuilder 7X00 interface cards, in addition to the Integrated
Fast Setup procedure, to correctly configure your system.
This section presents the Integrated Fast Setup of the CoreBuilder 7000
family ATM switch card. It also explains when to use the Integrated Fast
Setup of the CoreBuilder 7000 family ATM switch card and when to use
the Fast Setup of an individual Corebuilder 7X00 interface card. For
detailed information about how to use the Fast Setup of an individual
Corebuilder 7X00 interface card see the User Guide of the specific
interface card.
Chassis-oriented Setup
The Integrated Fast Setup procedure is based on the concept that the
CoreBuilder 7000 family ATM switch chassis together with its installed
interface cards is viewed as an integrated unit. The advantage of this
point of view is its simplicity: it is not necessary to remember in which slot
each interface card is installed or even which type of interface card is
installed. Attention is focussed on configuring the ports of the chassis.
The procedure automatically determines the ports that are available in the
chassis and presents them by type (Ethernet, Fast Ethernet, ATM) for
configuration. The port location is displayed by the notation <slot.port>
.
For example <3.1> refers to slot #3, port #1.

Chassis-wide vLANs
With the Integrated Fast Setup, Virtual LANs (vLANs) can be created
across the entire chassis. vLANs are set up in two stages. First, in the LE
Client section, a number of
requirement of the network. Next, in the Virtual Network Configuration
section, the potential vLANs become actual vLANs by having ports
assigned to them.
You need to define an administration “admin” vLAN to maintain SNMP
connectivity to each device in the network. Using the Integrated Fast
Setup you define one admin vLAN for the chassis; there is no need to
define separate admin vLANs for each interface card.
Note that from software version 3.5 on, the “admin” vLAN can now be
called by any other name providing the same name is used consistently in
the CB7000 and in all installed CB7X00 interface cards. When using the
Integrated Fast Setup, the name for the admin vLAN which is specified for
the switch module will be automatically chosen for the other modules
housed in the same CoreBuilder 7000 family ATM switch chassis,
overriding any existing admin vLAN names.

vLANs are created according to the
Setup Modes The Integrated Fast Setup provides two setup modes: the “Full” setup
mode and the “Switch” setup mode.
Full Setup Mode
The Full setup mode configures both the CoreBuilder 7000 family ATM
switch and the installed interface cards. It sets the required parameter
values in all the installed interface cards. The Full setup mode presents
only the most critical parameters; default values are assumed for the
remaining parameters.
This method is recommended for most users, especially for initial setup.
Only those systems that require specific parameter settings in one or
more of the installed interface cards will require the Switch setup mode
described in the next section.
Switch Setup Mode
The Switch setup mode focuses only on the CoreBuilder 7000 family ATM
switch and its ATM ports. The Switch setup mode is provided to allow you
to retain special settings in the interface cards; it does not allow any of
the installed interface card configurations to be changed. If you wish to
Integrated Fast Setup

alter the settings in an interface card you can use the Fast Setup of that
interface card after you are finished using the Switch setup procedure.
Setup Mode Selection
If one of the following situations is detected, the operator is prompted to
choose between the Switch and Full setup modes:
A Subnet Mask, Default Gateway or NMS Address different from that
of the CoreBuilder 7000 family ATM switch
A vLAN whose ATM connection is set to “No”
The name of the ELAN to which the default admin port (Port #1 in
each slot) is attached is not the same in all interface cards.
If none of these situations is detected, Full setup mode is automatically
selected.
If Full setup is selected, the parameters in the interface cards revert to
their default values.
Setting Special Parameters
If one or more individual interface cards requires one of the special
situations referred to in the previous section or needs to remain
unaltered, you need to do one of the following:
Setup Procedure
Sections
Use the Switch setup mode of the Integrated Fast Setup to set up the
CoreBuilder 7000 family ATM switch only and then use the Fast Setup
of each installed interface card separately.
Use the Full setup mode of the Integrated Fast Setup to configure the
CoreBuilder 7000 family ATM switch and all installed interface cards
and then use the Fast Setup for the particular interface card in order to
restore its special parameter values.

Interface Type Section This section prompts you for the ATM
interface type configuration of the ports on the Interface Modules which
are installed in the CoreBuilder 7000 family ATM switch chassis.
There are three interface types: UNI, E-IISP and IISP. The UNI type is
normally used when an edge device is connecting to a switch, the E-IISP
type is normally used when connecting to another CoreBuilder 7000 or
9000 switch, and the IISP type is used to connect to a device which does
not recognize the E-IISP protocol used by the CoreBuilder 7000 family
ATM switch such as switches of other vendors.
To enter the interface type configuration:
1 At the NNI type of port prompt, enter the NNI type for the port you just
specified. Enter “U” for UNI, enter “E” for IISP, or enter “I” for IISP.
2 Repeat step 2 until you have specified the interface type for all of the
ports that are in the Corebuilder 7000 family ATM switch chassis.

Additional Switch Configuration
The Integrated Fast Setup configures a minimum set of network
parameters - enough to get you started.
If you need to make changes or to perform additional configuration
tasks, use individual items of the LMA menus. These are all described in
the
CoreBuilder 7000 Family ATM Switches User Guide.
Some additional configuration tasks might be:
Configuring SVCs
CoreBuilder 7000 family ATM switches use standard UNI 3.0 or 3.1
switched virtual channel (SVC). SVC mode can be used when CoreBuilder
is in a backbone or workgroup topology, with PVC used whenever
necessary. ILMI enables automatic address registration for SVC. Addresses
can be registered manually via the LMA menus
Setting the Mode
The CoreBuilder will run UNI 3.0 SVC by default. You can work in UNI 3.1
by choosing this option in the signalling setup menu.
Setting Network Prefix and ATM Addresses
ATM addresses are essential for establishing a connection using SVC.
Most devices that support SVC, also support automatic address
registration through the ILMI protocol.
A network prefix is essential for address registration to be executed. Refer
to
CoreBuilder 7000 Family ATM Switches User Guide
for proper network
prefix setting.
For connectivity with devices that do not support ILMI, ATM addresses
can be set manually using the Add ATM address function under ATM
address setup in the Administration Console menus.
Configuring a PVC
Permanent Virtual Channels (PVC) can be used to connect to devices that
do not support switched virtual channels (SVC) standard protocols. In the
CoreBuilder 7000 family ATM switch you can create point-to-point (P2P)
and point-to-multipoint (P2M) connections. Use the Setup and
Configuration Connections menu, to create a PVC call, PTP or PTM. You
can also create an out VC in a PTM call, release a PVC call, release an out

Uploading the Configuration of a Card
Downloading the Configuration of a Card
Loading Software and Configuration Data by Batch Utilities
You can store (upload) the configuration of an installed card from its flash
memory to an external disk and restore it (download) to the flash
memory of the original card — or to the flash memory of a different card
of the same type — at a later time. You can perform this operation only
through the LMA and not via a SNMP management application like
Tr an s ce nd .
When the switch operates in single-IP Mode, you can use this facility to
upload the configuration of any of the installed cards through the LMA of
the switch card. When the switch is operating in multiple-IP mode, you
can use this facility to upload the configuration of the switch card only.
This feature lets you:
Backup your switch configuration in case of switch failure
Transfer the configuration from one switch to another
Maintain various standard configuration templates which can be
loaded according to requirement
The configuration upload works for individual cards installed in the
CoreBuilder 7000: either the active switch card or a CoreBuilder 7X00
Interface Card. You select the card whose configuration you want to
download or upload from a list of installed cards.
You cannot upload or download configuration parameters to a switch
card while it is installed as a redundant switch card. You need to remove
the card from the chassis, install it in a different switch chassis as the
active switch card and then perform the upload/download operation, as

Selected Data Types
Organizing
Configuration Files
The CoreBuilder 7000 allows you to upload selected types of
configuration data. The types of configuration data you can upload
depends on the card you selected. For the switch card, the types of
configuration data you can upload are as follows:
All Configuration Data
Platform Parameters
ATM Addresses
PNNI Configuration
LANE Security
PVC Connections
LECS Topology
LECS Order List
For a CoreBuilder 7X00 card, the data types are as follows:
Platform Parameters
Static
The uploaded configuration files can be named using a naming
convention of your choice. Normally, you will want to include information
about the data type, the card type and a date or other identifier in the file
name. For example, you might use file names like cfg_7000_12jun98 and
static_7600_1.
Activating the
Downloaded
Configuration
When you download configuration data from the files on the disk to the
card, you designate the card by its slot number. The slot can contain the
original card from which the data was uploaded, or it can contain
another card of the same type.
If you try to download configuration data which was uploaded from one
type of card type to another type of card, an appropriate error message is
issued.
When the configuration files are downloaded into flash memory, they
overwrite the previous information. The new parameters are not
activated immediately, but rather after the next reboot when they are

read from the flash memory. The CoreBuilder 7000 assumes that the user
wants to reboot the switch as soon as possible to activate the new
configuration parameters. Therefore, subsequent to a configuration
download, all LMA and SNMP set operations are blocked until the next
reboot – except for the configuration upload/download and reboot
operations.
It is recommended, therefore, to perform a configuration download only
when you are ready to reboot and activate the new parameters.
Cards should not be “hot swapped” after a configuration download until
after the next reboot.
Uploading the

To store (upload) the configuration of a card installed in the CoreBuilder
chassis from flash memory to disk, first make sure that the switch is

Supplies
The CoreBuilder 7000 family supports three kinds of power supplies: an
AC unit rated at 90A, and two DC units rated at 90A and 40A. You can
use each one of them in any CoreBuilder 7000 family ATM switch. The
power supply supports two output channels: one 5V DC channel which
supplies the CoreBuilder switch and the interfaces cards, and one 12V DC
channel which supplies the fans.
The CoreBuilder 7000 family power supplies are shown in Table 7-1.

Operation
Calculating the Power
Consumption of
CoreBuilder Switch
Load Sharing
The power supplies can operate in load-sharing mode; two 90A power
supplies can produce up to 180A. Providing that the power consumption
of the unit does not exceed 90 A, load-sharing allows one power supply
to serve as a backup.
Overloading
When the installed power supply is rated for less than the required power
consumption of the CoreBuilder module, the CoreBuilder will not
succeed in powering up. It will attempt to power up, hit the current
overload rate and turn the power supply off, going through this cycle
repeatedly until the load is reduced.
The power consumption of an entire CoreBuilder 7000 family ATM switch
unit is calculated by adding up the power consumption of the switching
card(s) and interface cards installed in the chassis. Normally, the values for
typical power consumption can be used in the calculation. Table 7-2
shows the typical power consumption values for the CoreBuilder 7000
family ATM switching cards and interface cards

This section describes when redundant switch cards and redundant
power supplies can be used in a CoreBuilder switch.
In order to determine whether a redundant switch card and/or an
redundant power supply can be used in a CoreBuilder switch, the total
power consumption of all installed cards must be examined. According to
the total power consumption, there are three possibilities, as the
following examples illustrate:
Installation I:
The total power consumption of a single switching card
(that is, no redundant card installed) and all interface cards exceeds 90A.
In this case, a Dual 90A supply is required so that the second power
supply cannot be redundant. A redundant switch card can be installed.
This “heavy load” installation is illustrated by the first example installation
in Table 7-3.
Installation II:
The total power consumption of two
switching cards
(i.e., redundant card installed) and all interface cards exceeds 90A but
without the second switching card the consumption is less than 90A. In
this case, either a redundant switch card or a redundant power supply
can be installed, but not both. This “medium load” installation is
illustrated by the second example installation in Table 7-3.
Installation III:
The total power consumption of two switching cards
and all interface cards does not exceed 90A. In this case, both a
redundant switch card and a redundant power supply can be installed.
Redundant Power Supply 7-7
The light load installation is illustrated by the fourth example installation
in Table 7-3.
In all installations that do not include multiple CB7600 cards both
redundant switch cards and redundant power supplies can be installed.

This section covers the following topics:
Need for a Redundant Switching Module
Identifying the Active Switching Module
Conditions for Switch-over to Redundant module
Switching Module Configuration Database
Info Based on the MAC Address
Resetting to Factory Defaults
A
redundant
switching module is a backup switching card that is capable
of performing all the tasks of the currently active switching module
should it fail. For this purpose, the redundant module’s data base is kept
up-to-date with network parameters that are configured in the active
switching module.
The redundant switching module is a necessary requirement in a
critical-mission network. When a switch module fails in such a network,
loss of data and interruption in transmission must be kept to an absolute
minimum.
As the CoreBuilder 7000 boots, the first of the two switch modules to
begin operating becomes the active switch module.
Conditions for
Switch-over to
Redundant module
Once the unit has booted, the active switch module can be identified by
the LMA command (1) SYS (4) SWM:
Active Switch: ACT LED flashes rapidly
Redundant Switch: ACT LED flashes once every 2 secs.
or by the ACT LED as follows:
The redundancy feature works for any combination of the CoreBuilder
7000 and CoreBuilder 7000HD switch modules installed in the chassis.
The switch-over to the redundant module will occur in the following
situations:
Removal of the main switching module from the chassis.
Malfunction of the main switching module.
Manual reboot of the CoreBuilder 7000 by LMA, Telnet (soft reboot)
or Transcend NMS.

During the switch-over, the redundant switch reboots itself and comes up
as the active one. A temporary dropping of all connections will occur
during the switch-over. The connections are re-established after the
switch-over process is complete.

Switching Module
Configuration
Database
Each switching module contains a configuration data base where the
switch configuration data is stored. In order that the redundant switching
module be ready to assume the role of the active switch, its configuration
database is updated from the active switch. This occurs in the following
situations:
When the switch is booted.
When the switch configuration is changed.
Not all of the configuration data is transferred from the active to the
redundant switch. The data that was not transferred must be updated
manually. The following table presents data which is transferred and data
which must be updated manually (see “Setting up Switch Module
Hardware Redundancy” on page 4-7).

Each switching module board has a unique MAC address burned into its
EPROM. This MAC address is used by the CoreBuilder 7000 for three
purposes:
For the IP stack
For the LES ATM address user part
For calculating a unique number to be assigned to the ELAN name.
xxxx
The ELAN names have the format ELANxxxx_y where
is a unique
number calculated using the MAC address and y is an integer from 0 to
15 automatically assigned to each of the 16 default LESs of the
CoreBuilder 7000. In this way, each LES has a unique ELAN name and
unique ATM address.
When a redundant switching card takes over after the primary switching
card fails, the IP address, the ELAN names and LES address remain the
same as they were in the primary switch.
Resetting to Factory
Defaults
Publishing the New MAC Address
A redundant switch that has become active sends a reverse ARP (RARP) to
publish its MAC address to the network devices.
For devices that do not learn MAC addresses from a RARP, you will need
to reset the IP address entry of the CoreBuilder 7000 in their device table.
The ELAN names and LES addresses (user part) will be changed only if the
user performs a reset to factory defaults by LMA (or TELNET).
After resetting to factory defaults, the MAC address burned in the active
switch EPROM will supersede the one stored in the FLASH memory
resulting in new ELAN names and LES addresses.
Resetting to factory default will cause all connections to be dropped until
the new ELAN names are updated in the LECs.
