Chapter 6 SCSI Module FRUs 6-11
6.4.2 Installing an EMU Module
1. With the power on, slide the new EMU module into the chassis until it is firmly
seated in the backplane and the module’s front panel is flush with the chassis.
Caution – Be sure that the EMU module is properly inserted into the guide rails of
the array.
2. Turn the thumbscrews on the top and bottom of the EMU module clockwise until
they are finger-tight, to secure the module.
Note – To ensure that a thumbscrew is finger-tight, tighten it with a screwdriver
and then loosen the thumbscrew counterclockwise a quarter-turn.

FRU
The Sun StorEdge 3310 SCSI array box FRU includes a chassis, its drive midplane,
and its backplane. This product is ordered to replace a box that has been damaged or
whose midplane or backplane has been damaged.
To make a fully functional array, you need to add the following parts from the
replaced array:
■ Drive modules
■ Two power supply/fan modules
■ Two EMU modules
■ One or two JBOD I/O modules (for an expansion unit or JBOD)
■ One or two RAID I/O modules (for a RAID array)
■ One or two RAID controllers (for a RAID array)
■ One terminator module
To install the individual modules, use the replacement instructions provided in this
guide.
