Procedure1. Ground yourself to the EXN4000 using the grounding leash that came with the
system.2. From the front of the rack, place the expansion unit onto the rails and slide it
in until the front mounting bracket of the expansion unit is flush with theframe rails of the rack.
3. At the front of the rack, using four black hex head M5 screws in the H2 and H8holes, secure the system unit to the rack by threading the screws through thesystem unit bracket and the rack frame rail into the threaded rail nuts. Tightenthe screws using the 7-mm nut driver.
4. From the rear of the rack, use two silver pan head M5 screws to attach the rearof the chassis to the rails, as shown in Figure 5.
Setting the speed switchMake sure that all expansion unit speed switches are set to the correct position foryour application.
If you are connecting to an N3700 storage system, the speed switch must be set tothe 1Gb position. If you are connecting to any other N series storage system, thespeed switch must be set to the 2Gb or 4Gb position, as required by the storagesystem.
Note: If you have both EXN2000s and EXN4000s in a single expansion unit loop,the speed setting for all EXN units must be set to the same speed (1Gb ifconnecting to an N3700, or 2Gb if connecting to any other N series system).
For information about 4Gb support for your filer model, see the or for your Nseries filer.

Note: You do not need to ground EXN4000s; grounding is done through thepower cords.
3. Turn on power to the EXN4000 storage expansion units and wait for the diskdrives to spin up.
Setting the storage expansion unit shelf IDsA unique shelf ID is required for each storage expansion unit within the entirestorage system.
About this task
A valid EXN4000 storage expansion unit shelf ID is 0 - 7.
If your storage system has SAS and FC storage expansion units, the storageexpansion unit shelf IDs do not need to be unique between the SAS and FCexpansion units. (FC expansion unit shelf IDs continue to be unique within eachFC loop. SAS expansion unit shelf IDs continue to be unique to all other SASexpansion units in the storage system, including the N3220 or N3240 system'sinternal SAS shelf ID.)
Visually verify that the shelf ID for each storage expansion unit is unique. If not,set the shelf ID as follows. For additional details, see the IBM System StorageEXN4000 Storage Expansion Unit Hardware and Service Guide.
Procedure1. Remove the front bezel if you have not already removed it.2. Press and hold the storage expansion unit shelf ID button �1� until the first
digit blinks.
3. Press the button until the correct number is displayed.4. Repeat steps 2 and 3 for the second digit.5. Press and hold the button until the second number stops blinking.
Both numbers start blinking and the operator display panel fault LEDilluminates in about five seconds.
6. Power-cycle the EXN4000 to make the new expansion unit shelf ID take effect.7. Replace the front bezel.
