eSAT/IN failure seen in Empower - WKB28560

SYMPTOMS

• eSAT/IN failure shows in Empower message center
• Instrument Failure message appears in the Run window
• eSAT/IN shows status ok? No in node properties
• 2695 shows status ok? Yes in node properties 
• Clearing DHCP entries and restarting in proper order does not resolve this issue

ENVIRONMENT

• e-SAT/IN Module
• Alliance HPLC System
• 2695 Separations Module
• Bus SAT/IN Module
• Empower 3
• LAC/E

CAUSE

Corrupt INSTSRV.DAT file

FIX or WORKAROUND

1. Take each system on the affected LAC/E offline by selecting the system, right-clicking, and selecting Bring Offline.
2. Delete each system on the LAC/E.
3. Go to Node properties > Configure DHCP tab, click on Configure DHCP, screen capture and save, highlight each entry, and Remove one at a time.
4. Go to Instrument tab of the same Node Properties and remove all instruments in the list by highlighting one at a time and then clicking Remove Instrument.
5. Go to C:\Empower\InstrumentServer\instsrv.dat and delete the file (note that deleting the instsrv.dat file deletes all system configurations on the node).
6. Log out of Empower and close all open windows, shutdown the LAC/E and all Instruments connected to it.
7. Start up in correct order: IEEE units need to be booted up first; do not start up the LAC/E until all IEEE units have finished initializing. Start up the LAC/E but do not open the software, and then start the Ethernet instruments one at a time. Do not move to the next unit until the first finishes initializing.
8. Log in to Empower, go to Node Properties, and inspect the Instruments tab  under OK?—all should say Yes.
9. Recreate systems by going to Configuration Manager, clicking File > New > Chromatographic system, and create systems with the same names and configurations as before.
