Server Options - DASD Expansion (3518) LCD and control panel not functioning
Applicable to: World-Wide
Abstract :
3518 LCD and control panel not functioning.
Problem :
The LCD panel is blank and the control panel buttons do not function properly.
Problem Isolation Aids :
The unit is a PC Server Enterprise Expansion Enclosure (3518) with one or more hot-swap backplanes installed.
Fix :
1. Shutdown the operating system on the Server.
2. Power off the Server and the 3518 enclosure.
3. Unplug the 3518 for at least five(5) seconds. This action will ensure a full reset of the bus.
4. Verify the Backplane Jumper configuration for J2 and J12 on the 3518. Refer to pages 439-440 of the March 1996 PC Server HMM (publication number S30H-2501-01) and the diagram below.
a. J2 (Backplane Address jumper): Jumper MUST be installed on the pins for Bank0 for a single backplane system. If additional backplanes are installed, each backplane MUST have a jumper on the appropriate pins to ensure proper operation.
b. J12 (Backplane SCSI ID jumper): No jumpers should be present on pins 7-8 (labeled SYSRST).
5. Reconnect the power cord and power on the 3518.

Note: 3518 Enclosures manufactured before 10/1/96 (MFG Date: 610 and earlier on the rear serial number label) shipped with a jumper incorrectly installed on J12. This jumper MUST be removed for proper operation.
