Shelf Controller Firmware Requirements

Version 5.0.16 requires one or two (for redundant operation) ASCs or ASC2s. If two Shelf Controllers are in place, they must both be at Version 5.0.16 (The active shelf controller will overwrite the firmware on the standby controller).

Shelf Controller Backup Boot Firmware Requirements

Both ASC and ASC2 Controller models should use ASC_BT_1.0.03 as their backup boot for proper operation.

Upgrade Considerations

Upgrades are only supported from Version 4.x. Shelves running 2.x and 3.x releases should be first upgraded to 4.x before upgrading to 5.x.

Smooth upgrade of AUSM-8P cards from releases 4.x to 5.0.1x is not supported. This was a design decision based on the fact that Forum compliant IMA and release 4.x (proprietary) IMA protocols have certain configuration parameters that do not have counterparts in the other protocol.

However, there is a minimal level of help for upgrade. The configuration and the connection database does not need to be re-initialized after an upgrade. Once the AUSM-8P firmware is upgraded and the AUSM-8P card is reset, the following will be true:

Please note that co-existing of release 4.x and release 5.0.1x AUSM-8P cards on the same shelf is not supported. This means that all AUSM-8P cards on a given shelf need to be upgraded at the same time.

For manual upgrades using the revup command from the CLI prompt, it should be taken care that the revision name is not longer than 20 characters otherwise it will fail to rename the file.

Additional Commands/Features

CESM: Configuration of T1 line with ESF framing and AMI line coding.

Allowed the configuration of a line in ESF and AMI line coding mode.

Additional Deliverables

There are no additional deliverables required for Release 5.0.16.

Features Not Supported

Obsoleted:

1. Modules running versions 2.X or 3.X are not supported as of Release 5.0.1x.

2. AUSM8 Proprietary IMA is no longer supported as of Release 5.0.1x. IMA ports must be converted to ATM Forum-compliant IMA.

Notes & Cautions

1. ASC's with flash disk have a high probability of disk failure if a write to the disk is interrupted. Writes can be interrupted while resetting the card, removing the card and for other reasons. Therefore, it is absolutely necessary that the disk should be queisced or downed before doing any operation that could interrupt a disk write. The 5.0.1x ASC firmware does an automatic queisce or downdisk for most of the cases in which a write to the disk can be interrupted. There are some scenarios where the downdisk has to be manually executed and there are some cases where it is not possible to do downdisk. The following table lists the various possible scenarios when a disk write can be interrupted.

Scenarios   Downdisk Operation  Comment 

Power Outage

Cannot be done

Flash disk is exposed to corruption if a write was being done at the time of power outage.

Manual Power Shutdown

Manual

Flash disk can be protected by doing a downdisk from CLI on Active and Standby ASC before power shutdown. Use option 1 in downdisk CLI.

ASC Removal

Manual

Flash disk can be protected by performing a downdisk on the ASC to be pulled out.

Watchdog timer reset

Cannot be done

Flash disk is exposed to corruption if a write was being done at the time of ASC reset.

ASC reset from CLI resetcd

Automatic

The firmware automatically shuts the disk before resetting the ASC.

Shelf reset from CLI resetsys

Automatic

The firmware automatically shuts the disk on both Active and Standby before resetsys.

clrallcnf CLI

Automatic

The firmware automatically shuts the disk on both Active and Standby after clearing the configuration and before resetting.

Shelf reset by task failure

Automatic

The firmware automatically shuts the disk before resetting the ASC.

ASC reset due to GRAM exception

Automatic

The firmware automatically shuts the disk before resetting the ASC.

ASC reset due to SAR exception

Automatic

The firmware automatically shuts the disk before resetting the ASC.

ASC reset because unknown reason

Cannot be done

The flash disk is exposed to corruption if a write was being done at the time of ASC reset.

For information on downdisk CLI to perform manual queisce of the hard disk refer to the section on Additional Commands/Features.


Note   These procedures when applied to all types of hard disks in the ASC increases their reliability and hence it is highly recommended to follow these procedures for all the hard disks.

2. ASC/B cards with Calluna Hard disk are exposed to failures due to EMI when all of the following conditions are present:

The workaround for this problem is:

This problem is more frequent if the service module used in slot 5 is CESM8. The problem is also seen with FRSM4 in slot 5 but the frequency is considerably less. This problem is present in all previous AXIS firmware releases.

Limitations

The tstcon command cannot be used between IGX/BPX/MGX. This is because whenever a tstcon is used the SWSW tells the remote end to be in remote loopback. In this scenario SWSW in BPX cannot directly communicate to any service card in AXIS hence the loopback command is not sent to FRSM. Because of this limitation the tstcon payload will be processed as a normal data payload and hence will not loopback.

The cell bus fixes and enhancements have not been done for ASC, AUSM-4T1E1 and FRSM-4T1E1, these cards are still exposed the problem of cards going to Reserved/Empty/ Failed state when doing either clrallcnf or resetsys or resetcd. The card has to be reset to recover from this limitation.

Once the ASC-RAS cycle starts, it can't be stopped in middle. So even if `delrasdsk' is issued while the RAS diagnostic cycle is in progress, the RAS status will become disabled but the current cycle will proceed to completion.

While the RAS cycle is in Progress on a shelf with two ASCs and `delrasdsk' is issued on Active ASC, the Active ASC will immediately show the RAS Status as `Disabled' whereas the Standby ASC will reflect the change only when it is through with its RAS specific testing.

The output of `dsplmistats' will not show the correct BPX status if a physical loopback is put on BNM. The BPX status is displayed as OK, which is not correct.

IMATM-8T1E1 does not work with UXM release ABD and below.

Overloading the BNM interface with traffic causes the AUSM cards to fail.

clralm -sonet will not clear 15min alarms on the ASC.

Known Anomalies
