8.3.1 Removal
1. Slide the SCSI tray into the chassis.
2. When the tray is halfway in, extend the injector/ejector levers toward you.
3. While holding the injector/ejector levers, slide the SCSI tray into the
chassis until the injector/ejector levers engage the metal on the chassis.
4. Seat the tray. Push both levers down simultaneously to maintain insertion
alignment until they are fully locked (down). Use care when doing so
avoid connector damage.
Caution – Do not force the injector/ejector levers in if the SCSI tray resists
seating in the backplane connectors. Forcing the tray in can damage backplane
or tray connector pins. Unseat the tray, and retry by gently closing the
injector/ejector levers inward until fully seated.
5. Tighten the four captive retaining screws.
Note – Due to normal machine tolerances, it is best to thread all four screws in
loosely (about 1-2 turns), then go around and tighten each screw.
6. Replace the EMI shield and the front panel.
Caution – Replace the EMI shield before operating the system. Sun
Microsystems Inc. is not responsible for regulatory compliance for a
SPARCserver 1000 System which is operated with the EMI panel removed.
The power supply is located in the lower front of the SPARCserver 1000 system
behind the front cover and EMI shield. See Figure 8-1.
1. Remove the front panel and EMI shield. See Chapter 7, "Internal Access."
2. Locate the power supply in the SPARCserver 1000 system lower front.
