Some OC48 line cards will not properly detect receive optical carrier when power cycled.
If a line card is powered up with a receive optical signal already present, it may experience this problem. If a line card is powered up and an optical signal is subsequently applied, this problem will not occur. An in-service product that experiences power cycling is at risk for this problem.
The line card fails to detect receive optical carrier, rendering the line card inoperative.
Line cards which exhibit this problem may sucessfully recover normal operation without user intervention after 2-10 minutes.
Line cards will sucessfully recover normal operation with user intervention by executing a microcode reload (if there is no recovery after the first micro-reload repeat the mircro-reload). Use the following command sequence to execute a micro-reload on a line card in slot x.
As of approximately June 25, 2001, all affected products were being manufactured under deviation D012224 which guarantees they will not exhibit this problem. Refer to the section How to Identify Hardware Levels below for instructions on how to view the deviation on an in-service product. Products shipped from logistics may still exhibit this problem at this time.
Customers who wish to proactively replace one or more of their affected products with units which do not exhibit this problem should call the Technical Assistance Center (TAC) and request a return materials authorization (RMA) coded ARFN (Administrative Request - Field Notice), referencing this field notice. This forces fulfillment from manufacturing instead of logistics.
Customers who wish to RMA an affected product due to this or some other failure but who want to ensure they receive a replacement which does not exhibit this problem should also request their RMA be coded ARFN, referencing this field notice. Because this forces fulfillment from San Jose, California manufacturing instead of logistics, it may not be possible to meet 2-hour, 4-hour, or next business day service level agreements.
An Engineering Change Order (ECO) is currently being written. Once the ECO is approved, it will be used to initiate a global purge of Service Logistics inventory. A global purge of Service Logistics inventory takes between 6 and 12 months. Once the global purge of Service Logistics inventory has been completed, customers can safely RMA product using Service Logistics inventory (will no longer need to code RMAs ARFN). This field notice will be updated when the global purge of Service Logistics inventory has been completed.

The OC48E/POS-SR-FC(=) product is not affected by this problem because it was never manufactured with the defective optical module.
See also Field Notice 16712 for other products affected by this problem, but which have a different recommended workaround.
