AT-S73, AT-S99 and AT-S102 Version 4.0.1 Software Release Notes

PN 613-001136 Rev. B 14 Allied Telesis Inc.

Operational Notes

 Starting in Version 3.0.0 the default operating mode for the AT-CM2 and AT-CM70S Line Cards is

OAM Visible. (The default operating mode for the AT-CV Line Cards remains Link Test.)

 To avoid compatibility issues between the AT-CV5M02 Management Card and the media converter

line cards in a chassis, all of the cards should have the same version of their management software

programs. For example, if the management card has Version 4.0.1 of the AT-S99 Management

Software, the AT-CM2 and AT-CM70S Line Cards should have Version 4.0.1 of the AT-S73

Management Software.

 The maximum frame sizes of the lines cards are:

— AT-CV Line Cards: 9000 bytes

— AT-CM2 and AT-CM70S Line Cards: 1522 bytes

— AT-CM2K0S Line Card: 1522 or 1632 bytes

— AT-CM3 Line Cards: 10240 bytes

 When a remote AT-CV1203 Chassis loses power on one power supply, there may be a delay of up to

25 seconds before the AT-CM Media Converter Line Card sends the first RPS failure signal. If power is

restored to the secondary power adapter before the signal is sent, the card does not send the signal.

 If you are updating the management software on multiple line cards and the procedure fails on one of

more of the cards, try updating the cards individually.

 The AT-CM202 and AT-CM212 Line Cards in the MissingLink mode may take up to three seconds to

establish links on their ports.

 If you are using TeraTerm Pro to manage the Converteon product, Allied Telesis recommends

upgrading to the most recent version of the program. This is particularly important if you will be using

XMODEM to download image files to the AT-CV5M02 Management Card or to the AT-CM Line Cards.

The XMODEM utility in some of the earlier versions of TeraTerm Pro is not compatible with the same

utility on the management card. The downloads will initially appear to be successful, but will fail when

the management card attempts to transfer the image files to the line cards.

 If the DIP switches that control the operating mode appear to be nonfunctional on a new media

converter line card, they might have been disabled during manufacturing. Resolving the problem

requires the AT-CV5M02 Management Card. You have to install the line card into a chassis that has

the management card and either reactivate the DIP switches or select another operating mode on the

line card. If you do not have the AT-CV5M02 Management Card, contact Allied Telesis technical

support at www.alliedtelesis.com for assistance.

 The SW 2 DIP switch block on the circuit boards of the AT-CM2 Line Cards has four switches. The

only active switch is switch 2, used to control auto-MDI/MDI-X on the twisted pair port. When the

switch is in the off position, auto-MDI/MDI-X is active on the port. When the switch is in the on position,

auto-MDI/MDI-X is disabled and the port defaults to the MDI-X configuration. The three other switches

on SW 2 are inactive.

 When you add or hot-swap line cards in an operational AT-CV5000 Chassis, Allies Telesis

recommends that you install the cards one at a time and that you verify with the management card that

a new card is operating properly before you install the next card.

 The Link LED for the fiber optic port on the AT-CM70S Line Card remains on after the port is disabled.
