Field Notice: *Expired* PA-H and PA-2H Revised HSSI Port Adapters


November 17, 1997

Revised February 24, 2006



NOTICE:


THIS FIELD NOTICE HAS BEEN ARCHIVED AND IS NO LONGER MAINTAINED OR UPDATED BY CISCO.

THIS FIELD NOTICE IS PROVIDED ON AN "AS IS" BASIS AND DOES NOT IMPLY ANY KIND OF GUARANTEE, WARRANTY OR SUPPORT. USE OF THE INFORMATION ON THIS FIELD NOTICE OR MATERIALS LINKED FROM THIS FIELD NOTICE IS AT YOUR OWN RISK. CISCO RESERVES THE RIGHT TO CHANGE OR UPDATE THIS FIELD NOTICE AT ANY TIME.


 

Products Affected 

This field notice affects the following products:
  • PA-H(=) 
  • PA-2H(=) 

Problem Description 

An overrun condition on the HSSI port adapters for the Cisco 7200 and Cisco 7500 systems was identified. 

As of November 17, 1997, Cisco released the PA-2H Rev. B. revised HSSI port adapters that corrected the overrun condition and dramatically improve performance under bursty and sustained traffic loads. Cisco strongly recommends that all installed PA-H and PA-2H port adapters be upgraded to the revised versions PA-H Rev. B and PA-2H Rev. B respectively. 

Revised PA-H and PA-2H port adapters can be identifiable by the text "Rev. B" in the lower-right corner of the front panel label.

The minimum Cisco IOS for the PA-H Rev. B and PA-2H Rev. B is as follows: 

PA-H Rev. B PA-2H Rev. B
Minimum 11.1 IOS: 11.1(12)CA 11.1(15)CA
Minimum 11.2 IOS: 11.2(9)P 11.2(11)P

Problem Symptoms 

During an investigation of performance problems on the HSSI port adapters, a problem with an ASIC on the PA-H and PA-2H port adapters was discovered. Both the PA-H and PA-2H were put on line stop in early May, 1997 and a mandatory recall program initiated. 

Packet loss of up to .1% (overruns) has been observed resulting from this ASIC problem on the HSSI port adapters. In rare circumstances this overrun condition has been observed to precipitate packet-handling anomalies. 

This condition has no other affect on system-level operation. 

If you are a registered CCO user and you have logged in, you can view the bug details.

Workaround/Solution 

Hardware and software changes have been made to the PA-H and PA-2H HSSI Port Adapters which correct the port adapter specific condition. Cisco strongly recommends that customers upgrade all PA-H and PA-2H HSSI port adapters. 

Revised PA-H and PA-2H port adapters can be distinguished by the text "Rev. B" in the lower right-hand corner of the label. In addition, the Cisco IOS commands show diag and show ver can be used to identify PA-H cards installed in a chassis and the system software level. Revised PA-H and PA-2H port adapters can be identified by the following numbers: 
 

Port Adapter New Revision Level (or later)
PA-H PN 73-2559-01 Rev. A0 HW-V 1.0
PA-2H PN 73-2914-01 Rev. A0 HW-V 1.0

Beginning November 17, 1997, customers may request replacement PA-H or PA-2H HSSI Port Adapters on a port-for-port basis at no charge.

Identifying Hardware Levels 

You can identify the hardware version of your port adapter by using the Cisco IOS command show diag

Configuration Limitations 

The PA-H and PA-2H were originally released with maximum configuration guidelines. These guidelines limit the maximum number of PA-H or PA-2H cards that can be placed in a chassis as shown below: 
Chassis Type PA-H PA-2H
Cisco 7513 12 12
Cisco 7507 4 4
Cisco 7505 4 4
Cisco 7206 3 3
Cisco 7204 3 3
In the Cisco 7500 series, the limitation is imposed by the power requirements of the HSSI PAs. Exceeding the limits above may cause the power supply circuit breakers to trip on power up. 

In the Cisco 7200 series, HSSI port adapters are classified as a high speed port adapters. There is a limit of three high speed port adapters in a single Cisco 7200.

Physical Replacement of Port Adapters 

On the Cisco 7200 series, the PA-H, PA-2H, port adapters are hot-swappable and can be replaced with a PA-H Rev. B or PA-2H Rev. B without turning off the system. On the Cisco 7500 series, port adapter OIR is not supported, and the entire VIP card must be removed prior to replacing a port adapter. 

For more information on how to replace a PA-H or PA-2H port adapter, please read "PA-H HSSI Port Adapter Installation and Configuration" or " PA-2H Dual-Port HSSI Port Adapter Installation and Configuration".
