This document describes the functions of the NVRAM/TOD (Time Of Day) chip in a Sun Enterprise[TM] 3X00 - Sun Enterprise[TM] 6X00 system. It describes when it is needed to be replaced, what to expect during replacement, and how to copy idprom information from one TOD chip to another within the system. SolutionSteps to FollowBackground information on the NVRAM or TOD Chip: The component itself is a "M48T59 NVRAM" chip (pn 100-4007) and is located on the Clock Board and all I/O Boards in a Sun Enterprise 3X00-6X00 system. The component is actually a battery plus seeprom. It is commonly called any one of several terms:
The chip contains the following information:
How it functions: Copies of this data reside on the Clock and all I/O Boards for redundancy. During the POST process, the NVRAM on the Clock Board is compared to the NVRAM(s) on the I/O Board(s). If the data on the Clock Board matches the data on at least one I/O Board, the data on the Clock Board is automatically synchronized to all I/O Boards. In systems with only one I/O Board, it is important to follow the Clock Board replacement procedure correctly to retain the data located on the NVRAM chip. If the data is not retained, the hostid will change which will cause problems with software that uses hostid-based licensing. If the Clock Board cannot find one I/O Board with matching NVRAM information when POST completes, the following message will be displayed: Clock TOD does not match TOD on any IO boards This message refers to the TOD chip, not the time of day value. To rectify this, the NVRAM data needs to be copied. Two OBP commands perform the copy function of NVRAM information:
These commands only mention "tod"; this refers to the chip, not the time of day value. The copy-clock-tod-to-io-boards command copies the data from the Clock Board to all I/O Boards. The copy-io-board-tod-to-clock-tod command copies the data from the I/O Board specified (in hex) to the Clock Board. The following scenarios explain how to copy the NVRAM/TOD data based on the part replacement performed: 1. When an I/O Board is replaced in a system with more than one I/O Board, the Clock Board will overwrite the TOD NVRAM on the new I/O Board so it is in sync with the rest of the system. 2. When an I/O board is replaced in a system with one I/O board,the Clock TOD does not match TOD on any IO boards error is always displayed. 3. When replacing a clock board, it is advantageous to copy theNVRAM information from an existing I/O Board to the Clock Board using the copy-io-board-tod-to-clock-tod command. If the NVRAM data is copied incorrectly (ie. in the wrong direction), the following problems will occur:
There is no way to verify the contents of the NVRAM chip on the Clock Board or the I/O Board. The banner command will show whatever POST has determined to be good data. POST will output a message (see below). As mentioned before, the NVRAM chip has a built-in battery to retain its data. The only way to fix a dead battery is to replace the NVRAM chip (ie. replace the Clock or I/O Board). If the battery is dead, the following messages will appear during POST: 5,0>ERROR: TEST=NVRAM Devices,SUBTEST=M48T59 (TOD) Init ID=8.1 NOTE: Patch 103346-30 contains the latest firmware and was released Oct/30/2002.

Not sure this is still in place (checking...) but this is the text of that link: Title: NVRAM/SEEPROM Replacement Procedure Document #: SCRP1016 Sun Proprietary: Internal Use Only 1.0 Objective: To provide US Sun Service personnel with instructions to ensure timely replacement of a failed NVRAM/SEEPROM at customer's sites and ensures appropriate records are maintained of these replacements. 2.0 Scope: This procedure defines the actions and responsibilities of all personnel, but not limited to Field Engineers, Technical Support Engineers, System Support Engineers, ROCA, and Supplier. 3.0 Procedure Summary: (Flowchart to be added with next revision) Case initiated or already exists Appropriate NVRAM/SEEPROM ordered NVRAM/SEEPROM received NVRAM/SEEPROM replaced Case Closed. 4.0 Procedure Detail: Responsibilities, Action, References and Notes Request for service or request for assistance. Customer, CCC, SSE, and/or FE See Note 1 Does the customer have software applications "tied" to the HostID and/or Ethernet address? SSE/FE If yes, See Note 3 If no, See note 2. Upon receipt of replacement, Engineer installs NVRAM/SEEPROM and ensures system functionality. Was replacement NVRAM/SEEPROM provided by PDSi? SSE/FE If yes, See Note 4 ERM See Note 5 Close case. Notes: 1. Service Calls are initiated by calling 1-800-USA-4-SUN. If Case already exist, then engineer can call FE Technical Support at 1-800-USA-1SUN for additional assistance. 2. FE or SSE places order for FRU replacement through USCO call center at 1-800-776-0996 or through PDSi at 1-800-882-8282 for the following non-FRU's: 2.1 NVRAM JavaStation JJ P/N 525-1733-xx 2.2 SEEPROM Sunblade 1000 P/N 525-1788-xx 2.3 SEEPROM Sun Fire V480 P/N 100-5311 2.4 SEEPROM Sun Fire V880 P/N 100-5311 3. TSE, SSE, or FE must copy and paste the following information and send to PDSi via the NVRAM/SEEPROM email alias:[email protected] Subject line: Americas FIELD REQUEST FOR DELIVERY OF A REPLACEMENT NVRAM/SEEPROM: Body of Case Number (mandatory) email: Part Number (mandatory) Task ID Number (mandatory) Request Date (mandatory) Delivery Address (mandatory) Delivery Contact Name (mandatory) SSE/FE Name (mandatory) SSE/FE Phone # (mandatory; PDSi may have questions about the order) Required Date (state urgency or Mission Critical status) HostID (if known) Ethernet Address (if known) Barcode Serial Number (mandatory) Platform Type (mandatory) PDSi receives the email and recreates the NVRAM/SEEPROM. Depending on the urgency or mission critical status indicated in the email template, PDSi can expedite the replacement NVRAM/SEEPROM directly to the location specified by the engineer. Normal business hours for PDSi are from 8:30 am to 5:30 pm, EST. However for after-hours support, call 1-800-882-8282 and follow the instructions of the automated attendant. Be sure to leave your name and phone number--you will be contacted within 1 hour of your call. Shipping of the replacement NVRAM/SEEPROM can range from UPS ground to NFO, depending on the customer's requirements or contractual commitments. The newly recreated NVRAM/SEEPROM shall be identified with a "WHITE" barcode label that includes the human readable "serial number". 4. It is mandatory for the original NVRAM/SEEPROM to be returned to PDSi for proper disposal and tracking. 5. PDSi will track information on the duplicated NVRAM/SEEPROM, including the hostID, ethernet address, platform type, barcode serial number, date, and engineer name. A bi-weekly aging report will be sent to the Repair Management Manager indicating the non-returned defective NVRAM/SEEPROM's. Repair Management will escalate as necessary to ensure field return compliance. PDSi will contract for the destruction of the defective NVRAM/SEEPROM, and will maintain Certificates of Destruction for each NVRAM/SEEPROM destroyed. 5.0 References: 5.1 FLDP1007 - Hardware Installation 5.2 FLDP1008 - Hardware Service Delivery and Escalation 6.0 Definitions: 6.1 CCC - Customer Care Center 6.2 FE - Field Engineer 6.3 FRU - Field Replaceable Unit 6.4 NFO - Next Flight Out 6.5 SES - Supplier Engineering Services 6.6 SSE - System Support Engineer 6.7 TSE - Technical Support Engineer 7.0 Performance Criteria: 7.1 Performance Criteria will be added with next revision. 7.2 Quality records are to be maintained as follows: Quality Records Department Responsible Department/Location Record keeper Retention Period Location Aging Reports Vendor Vendor 6 months Onsite Certificates of Destruction Vendor Vendor forever Onsite Change Record Revision: 00 Date: 11/17/03 ISO9001:2000 Clause: 7.5.1 Prepared by: Dan Scully Authorized by:Andy Macnamara, Manager, Repair Supplier Management Doc.
