Description:

It has been determined that, due to a hardware circuit anomaly, single port Gig I/O modules (all XLR1101SX and XLR1101LX models) can cause Accelar 1100 and 1150 switches to randomly and/or continuously reset.

Discussion:

If you have XLR1101 I/O module(s) with manufacturing date(s) prior to July 19,1999 in your network, please be advised that unexpected random, and possibly continuous, resets to the Accelar 1100 (XLR1100) and Accelar 1150 (XLR1150) switches containing these modules may occur.

All XLR1101SX and XLR1101LX I/O modules indicated by the product and corresponding order numbers listed above, manufactured before July 19, 1999, are affected. XLR1101 modules manufactured or reworked on or after July 19,1999 do not exhibit the anomaly and are not affected by this CSB.

Product Identification

• XLR1101 I/O modules must be removed from the chassis in order to examine the date code.
• The chassis itself NEED NOT be powered down during module removal and other modules in the chassis will not be affected.
• The date code can be found on the bottom side of the metallic chassis that is affixed to the module, adjacent to the product order (DJ or UGDJ) number.
• Products with date codes prior to 071999 (on or before 071899) are affected.
