IBM EXN4000, Installation And Setup Instructions

Page: 12 / 18

Procedure
1.
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 the
frame rails of the rack.
3. At the front of the rack, using four black hex head M5 screws in the H2 and H8
holes, secure the system unit to the rack by threading the screws through the
system unit bracket and the rack frame rail into the threaded rail nuts. Tighten
the screws using the 7-mm nut driver.
4.
From the rear of the rack, use two silver pan head M5 screws to attach the rear
of the chassis to the rails, as shown in Figure 5.
Setting the speed switch
Make sure that all expansion unit speed switches are set to the correct position for
your application.
If you are connecting to an N3700 storage system, the speed switch must be set to
the 1Gb position. If you are connecting to any other N series storage system, the
speed switch must be set to the 2Gb or 4Gb position, as required by the storage
system.
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 if
connecting 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 N
series filer.
