The power supply in an affected AC PIX-515 may short out if the unit is turned on its side during operation. There is no safety hazard; the electric discharge is contained within the power supply.
Some PIX-515 models manufactured from June through September 2000 have defective AC power supplies. Other PIX models and PIX-515 models with DC power supplies are not affected.
When the power supply is shorted out, the PIX-515 will cease functioning immediately or will fail to power on after being turned off at a later time.
The workaround is to avoid repositioning the PIX-515 while it is powered on. Especially avoid turning the unit on any of its sides or upside down.
The solution is to replace the defective power supply with a good unit. Please contact the Technical Assistance Center (TAC) and request a return materials authorization (RMA) to request a replacement AC power supply kit PIX-515-PWR-AC=.
How To Identify Hardware Levels
To identify a potentially affected unit, determine if its model, hardware revision and serial numbers fall within the affected ranges. All three numbers will be printed on the rear of the unit. If the numbers fall within the affected ranges, then the unit potentially contains a defective AC power supply, and you may request a replacement kit by contacting the TAC.
If you wish to conclusively determine if a unit has a defective power supply before ordering a replacement kit, then you must inspect the power supply.
Open the PIX-515 chassis by following the instructions in the Opening a PIX Firewall Chassis section of the Installation Guide for the Cisco Secure PIX Firewall.
When the chassis is open, look for the manufacturing date code on the power supply label. Compare the date code against the following table to determine if the power supply is defective or not.
"0009 C#" through "0038 C#"
"0030 P2" or "0040 C2"
Note:?Some power supplies with the bad date codes were repaired before shipping. If a green dot sticker is present on the power supply label, then it has been repaired and is not subject to failure.
Physical Replacement of Parts
Complete power supply replacement instructions are included in the power supply replacement kit.
PIX Firewall Serial Numbers
PIX 525 serial numbers as reported by the show version command have their first two characters truncated. For example, if the PIX chassis serial number is 44480521234 it will be reported by show version as 480521234. The first two characters cut off are always 44.
