i. Power down your system.
ii. Disconnect all HP-MSIB cables.
iii.Remove the Clock Source from the Display.
2. Check the Display as follows:
i. Power on the Display.
ii. Is there an E (flashing or steady) on the display?
If YES, then the Display is faulty.
If NO, power down the Display then go to step iii.
iii.Connect a known good HP-MSIB cable between the IN and OUT HP-MSIB ports
on the rear panel of the Display, then power on.
iv. Is there an £ (flashing or steady) on the display?
If YES, then the Display is faulty.
If NO, power down the Display, remove the HP-MSIB cable, then go to step 3
3. Check the Clock Source as follows:
i. Plug a Clock Source into the Display, then power-on.
ii. Is there an E flashing on the Display or ERR flashing on the Clock Source?
If YES, then the Clock Source is faulty.
4. Check the Agilent 70843 as follows:
i. Connect known good HP-MSIB cables between the IN and OUT HP-MSIB ports
on the rear panel of the Display and Agilent 70843, then power on.
ii. Is there an E (flashing or steady) on the display, or is the HP-MSIB or I/O CHECK
indicator lit?
If any error indicator is lit, check that the Display and Agilent 70843 are properly

flashing on the display then the Agilent 70843 is faulty.
