H134356 - 3518 LCD AND CONTROL PANEL NOT FUNCTIONING SYMPTOM: 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. .------------------------------------------------------------. | J2 | |.. Bank2(E) | |.. Bank1(D)----- ----- | |..
