Installing an EMM or SCSI Terminator Card
1. Carefully insert the EMM or SCSI terminator card into the empty module slot.
2. Push the module to the back of the slot until it is firmly seated in the backplane connector (see Figure ).
3. Using a #2 Phillips-head screwdriver, tighten the captive screw at the top of the module to secure the module to the
chassis.
4. If necessary, update the firmware for your EMM(s). See the Dell Support website at support.dell.com for the latest
information on firmware updates.
NOTE: If you have two EMMs installed, both must be running the same firmware level. Also, both EMMs must be
the same speed. (A label on the EMM identifies whether the module is a U160 or a U320.)
For information on EMM connections and cabling, see " Connecting the Storage System ."
