CPU Blades
The illustration below shows the location of slots used to accommodate CPU Blades. In principle, these
CPU blade slots should be populated from left to right, in the order of slot1, slot9, slot2, slot 10, and so on.
Install a CPU blade slot cover in a vacant expansion slot with no CPU blade contained.
In such cases, note the following:
 When installing half-height, double-width CPU blade, use two horizontally adjacent slots starting
with an odd slot number (for example, slots 1 and 2).
Two adjacent slots starting with an even slot number (for example, slots 2 and 3) cannot be used.
 When installing a full-height, single-wide CPU blade, use two vertically adjacent slots (for example,
slots 1 and 9). Blade slots are separated by full-height, double-width partitions (slots 1/2/9/10, slots
3/4/11/12, slots 5/6/13/14, and slots 7/8/15/16). The partitions do not allow CPU blades of different
heights to be mixed. Note that CPU blades of different widths can be mixed.
* For information on CPU blade sizes, see “Supported CPU Blades” on page 57.
* Different criteria from the above may apply depending on the type of modules installed. In such case,
follow the instructions given for the relevant module or in its user’s guide.
Use two vertically adjacent
slots for full-height,
single-wide modules
(for example, slots 1 and 9
as shown in the figure).
Slot 1
Slot 8
Use four vertically and
horizontally adjacent
slots for full-height,
double-wide modules.
(for example, slots
7, 8, 15, 16 as shown
in the figure).
