PictureTel Prism

Release 1.1 Upgrades

This release expands the videoconferencing capabilities of the Prism
videoconferencing bridge by improving the applications software
and adding support for several new hardware modules and
configurations.

Prism 1.1 Upgrade Kits

Prism 1.1 supports several new hardware and software featur es that
greatly expand the bridge’s capabilities. Several combinations of
these features are bundled together into upgrade kits that can be
fitted to Prism 1.0 bridges. In addition to these two dual-BPU-based
kits, two upgrade kits that package already-available modules have
been released with Prism 1.1.

❑

Dual Bridge Processing Unit (BPU) upgrade kits
These two kits add an additional BPU to the bridge. This give

the Prism the processing power to manage larger
videoconferences that include more sites or multiple
conferences. With the second BPU, a Prism can handle up to:

• One eight-site conference

or

• Two simultaneous conferences with up to eight sites

The second BPU is available in two kits, bundled with either a
dual-port ISDN communications module or a single Quad BRI
communications module to provide more communications
capacity.

• A Dual-port ISDN module allows two PRI ISDN lines (E1 or
T1) to be connected to a single module, effectively doubling
the ISDN bandwidth available for conferences.

1-1

PICTURETEL PRISM RELEASE 1.1 UPGRADES

• A Quad BRI module allows four additional BRI ports to be
connected to the Prism

❑

Two Quad Basic Rate Interface (Quad BRI) modules kit
With this kit, users who curr ently have a switching MCS with 8

BRI connections can double its capacity to 16 BRI direct
connections.

❑

Continuous Presence (CPM or VPU) module kit
Adding a CPM module allows the video mix in a multipoint

conference to display up to four sites.

Time Requirements

Before Y ou Begin

When planning installation of an upgrade kit, you should allow
from four to eight hours to back up the bridge’s existing software,
install new software and new hardware modules, connect to the
network, create new configurations, and test the installation.

If the site has a current full-image backup of the entire hard drive,
not just of the database, the installation may take one or two hours
less.

If the upgrade will use new connections to the network, more time
may be required to resolve network problems.

Before you begin the upgrade procedure, make sure you have:

❑

Blank tapes for system backups

❑

Tools:

• Phillips and straight screwdrivers

• Grounding strap

• Antistatic mat

• Network line testing and diagnostic equipment (for kits that
include communications modules)

❑

Copies of the

PictureTel Prism User’s Guide

and the

PictureTel

Prism Installation Guide

❑

For a kit that includes a second BPU, a complete set of options
diskettes for the Prism.

T I P

During installation of the second BPU you must reinstall

all

the options diskettes that came with the Prism. Locate these
diskettes before starting the upgrade or you will not be able
to complete the procedure.

If there is any possibility that the modules already in the
Prism have been modified in any way since the unit was
manufactured (for example, if modules have been replaced
or added, or that some modules’ I/O addresses have been
changed), use the Workstation software’s configuration
tools to get a report of the current configuration that
includes each module’s I/O address.

This is very useful information to have when you assign slot
positions and I/O addresses to the new hardware modules.

In addition to the tools and materials, check the contents of each kit
you will install to make sure each is complete.

Backing Up the Current Software

Removing Non-Essential Files

Before you begin the upgrade procedure, back up the current
installation. This will be helpful if you need to restore it at any point
during the upgrade. If you need to restore the current installation,
refer to the

PictureTel Prism User’s Guide,

Chapter 9.

During normal operation, a variety of non-essential log and tracking
files are generated. These may be removed before performing the
backup.

To remove log, accounting, and tracking files from the MCS before
performing a backup:

1. Change directories to

C:\mcu_prnt

.

On the Prism console, in a Workplace Shell window, at a shell
prompt, enter:

CD C:\MCU_PRNT

2. Remove the *.trk, *.ac? and *.evt files.

At the shell prompt, enter these commands:

DEL *.TRK
DEL *.AC?
DEL *.EVT

Note: It is normal to see some error messages indicating

that some files are in use and cannot be deleted. This
is because the files for active processes are open;
open files cannot be deleted.

2-2

Backing Up All Software to Tape

The procedure in this section describes how to back up everything
on the Prism hard drive to tape.

Caution

Do not skip this step. If anything goes wrong during the
upgrade, you’ll be able to recover by restoring this tape.

Backing Up the Current Software

You must back up the MCS software to a formatted tape—or several
tapes—which you provide for this procedure. Do not use the MCS
Base Software tape to back up the MCS software.

To back up the software:

1. Insert a blank formatted tape into the MCS tape drive.

2. Run the backup program.

a. On the Prism (not the Workstation PC), open a shell

window.

b. At a C:\ prompt, enter: BACKUP.

After the MCS reboots, BackMaster backs up the entire hard
disk and then a prompt to reboot the system is displayed.

Note: If you see an error message, correct the error and

repeat this step.

3. Reboot the MCS to return to normal operation.

2-3

UPGRADING THE MCS SOFTWARE

Installing the MCS Application Software

To install Prism software Version 5.0C:

1. After the startup messages are displayed and the boot routine
finishes, insert the
diskette into the diskette drive.

3. Answer
the existing database.

4. Remove the last application installation diskette from the MCS.

No

when the screen prompt asks if you want to overwrite

The installation instructions should prompt you to remove this
diskette while the MCS is resetting, before it boots. If you are too
slow in removing the installation diskette, the bridge may boot
from the diskette instead of from the hard drive as it should. If
this happens, you will see operating system error messages
because there is no operating system on the installation
diskettes. Make sure the diskette is not in the drive, and press
the Reset button to let the bridge boot from the hard drive.

5. After you have installed the software, the MCS reboots and begins
to bind the database and software.

This can take 10-30 minutes, depending upon the size of the
database. When that process completes, the new MCS software
loads.

2-4

Installing the MCS Application Software

Installing the Second BPU’s Option Software

If you are adding a second BPU, you need to install the 7-slot
chassis/8-user option installation software, as well as reinstall all
the options software that was included with your Prism. If you are
not adding a second BPU, skip this task.

1. Rename the existing chassis option file.

Open a Workplace Shell window, and at the C:\ prompt, enter
these commands to change directories and rename the file:

CD \QM
REN QM.QM QM.OLD

2. Insert the diskette labeled 7-Slot Chassis/8-User Option into the
diskette drive.

3. Load the Option software.

In a Workplace Shell window at the C:\ prompt, enter:

control a Prism 1.0 or Montage™ 4.x or lower MCS), that
software’s icons will be replaced by the current
version’s.

and

2-7

UPGRADING THE MCS SOFTWARE

Caution

If multiple versions of W orkstation software are installed on
the PC, be sure never to run more than one version at a time.
To completely eliminate any potential for conflict, it is
strongly recommended that Windows be shut down and
restarted when switching between versions.

9. Using the Workstation, reconfigure the MCS to reflect the new
configuration.

Testing the New Software

Backing Up the Current System

At this point, you’ve completed the software portion of the upgrade.
It’s a good idea to test the software at this point, before any changes
are made to the hardware or the Prism configuration settings.

To test the new software, conduct a defined videoconference that
includes sites that you are sure are operating properly. This test
confirms that the Prism is operating correctly with the new software.
If you encounter errors, resolve them before installing any new
hardware modules.

Make a backup copy of the upgraded MCS database and system
software at this point, before you make changes required by new
hardware modules that may be added.

Caution

Because the restoration process cannot copy a database
from one software version into a differ ent version, you must
back up a database from, and restore it to, the same softwar e
version. Therefore, every time you install a new software
version, you should back up the database immediately
because the old database is likely to be unusable by the new
software.

12. Install all modules using proper ESD practices.

a. Grasp the module by its edges, and ensure that the

backplane connector faces down and the external
connectors face the back of the unit.

b. Slide the module into the slot, and align the backplane

connector with the backplane slot and the external
connectors with the opening in the back of the chassis.

c. Push the module firmly into the backplane and replace the

screw.

13. Reconnect the internal ribbon cable and any external
communications cables.

UPGRADING PRISM HARDWARE

Note: When adding a second BPU or a Continuous

Presence (CPM) module, you must connect the 3­position bus cable included in the upgrade kit across
the top of the modules.

Ensure that the keys on the ribbon cable connectors are properly
oriented. Refer to similar connections to verify the orientation.

If you need slack in the ribbon cable, disconnect it from the other
modules in the MCS until you can make the connection. Then
reconnect the ribbon cable to the other modules.

14. Replace the module retaining bar and screw it in place.

15. Replace the Prism’s exterior cover.

16. Attach the AC power cord to both the MCS and the wall outlet.

17. Power on the MCS.

Configuring
Modules

Each new or relocated module that manages communications in the
Prism (Quad BRI, T1/ISDN, and E1/ISDN) requires site-specific
information to be entered into the MCS database before the Prism
can be used.

For specific configuration information, refer to the PictureTel Prism
Installation Guide as follows:

❑ Task 10, Configuring a Module
❑ Task 11, Activating a Configuration

Testing the New Installation

Notes: If you installed a second BPU, it needs to be configured,

but the only information that needs to be entered into
the database is the module’s I/O address. Because dual­BPU configurations were not supported by Prism 1.0,
the procedure to follow is not documented in that
release’s PictureTel Prism Installation Guide.
If you have only the Release 1.0 documentation, follow
the general procedure for any other module, specifying
I/O address 0780.

If you installed a CPU, it does not require module­specific configuration. However, for it to be used,
conference and site definitions must be modified by
activating the appropriate Continuous Presence
checkboxes.

Testing the New
Installation

Backing Up the New Database

Verify that the hardware was successfully installed by setting up a
new conference definition that uses the new hardware and includes
sites that you are sure are operating pr operly, and then conduct the
conference.

For more information on running a test conference, refer to the
PictureTel Prism Installation Guide, Task 12.

Provided that the test conference works, make a backup copy of the
upgraded MCS database to a diskette to establish a baseline before
more configuration changes are made by the site administrator.
