Netfinity 5500: Beep code or lost video upon adding memory
Applicable to: World-Wide
SYMPTOM:
- POST results in a 1-3-1 beep code, no video, and one or more DIMM error LED's (CR8, CR9, CR10, CR11) on the Processor Board are activated.
------------------ OR ---------------------------
- No video upon power-up of the system, and the system cooling fans function.
NOTE:
Refer to the System service label (located on the Server) or the Netfinity User's Handbook, or the IBM Netfinity 5500 HMM (Hardware Maintenance Manual) p/n10L9800 for information on location of CR8 through CR11 on the Processor Board.
PROBLEM ISOLATION AIDS:
All of the following must be true for this tip to apply:
- The system is a Netfinity 5500 server Type 8660 model 11U, 11X, 1RU, 1RX, 41U, 41X, 4RU, 4RX.
- The system exhibits either of the described Symptoms (listed in the "Symptoms" section of this document) ONLY after adding one or more supported registered DIMM in the system. (Currently 256MB is the only supported Registered memory.)
FIX:
1- Power-off the server and any peripheral devices and disconnect all external cables and power cords, then remove the top cover.
2- Locate Jumper pins J12 on the Processor Board, and ensure the jumper block is located on pins 2 and 3. See Netfinity 5000 - Memory Module Kits for a picture of the J12 jumper location.
3- Re-install the top cover, reconnect all external cables and power cords, power-on any peripheral devices, then power-on the server to verify this fix.
NOTE:
To determine the location of J12, refer to the Netfinity User's Handbook, or the IBM Netfinity 5500 HMM (Hardware Maintenance Manual) p/n10L9800 for information on "Preparing to Install Options", "Top Cover Removal" and "Processor Board Component Locations".
