* There are two types of mezzanine cards that can be installed in the mezzanine slots: Type-1 and
Type-2. Also, there are two types in the numbers of ports to be connected to a switch module: two and
four.
* Mezzanine slots for Type-1 can accommodate Type-1 mezzanine cards only.
If you mount a mezzanine card, this card connects to two switch module slots.
(The port numbers of mezzanine slots for Type-1 differ depending on the types of CPU blades. Refer
to the connection diagram on previous pages.)
* Common mezzanine slots for Type-1 and Type-2 can accommodate both types of the mezzanine cards.
If you mount a mezzanine card with two port numbers, this card connects to two switch module slots.
If you mount a mezzanine card with four port numbers, this card connects to four switch module slots.
* The correspondence between the mezzanine slots and the switch module slots differ depending on the
types of CPU blades. Refer to the connection diagram on previous pages according to your choice of
CPU blade.
The below chart lists the mezzanine cards and the compatible modules. Verify your mezzanine card and
confirm the compatible modules. Ensure to use the proper combination. If you mount mezzanine cards on
the mezzanine slots, verify the type and port numbers of mezzanine card to use and mount them to
the appropriate slots.

*1 Compatible to GbE intelligent switch (L2) (N8406-022), GbE intelligent switch (L3) (N8406-023) and
GbE pass-through card (N8406-029).
*2 Compatible to 4G FC switch (12 ports) (N8406-019), 4G FC switch (24 ports) (N8406-020) and 2/4G
FC pass-through card.
Note that there may be limitations to the locations of connectable CPU blade slots and mezzanine slots
when you mount FC switch (12ports) (N8406-019). As to the locations of connectable CPU blade slots,
refer to “CPU Blades”. As to the limitations of corresponding mezzanine slots, refer to the connection
diagrams corresponding your CPU blade.
*3 Compatible to 10GbE intelligent switch (L3) (N8406-026).
* If there is no description on products that correspond to your cards, contact NEC's sales representative
and obtain the latest user's guide. (Mezzanine cards that have no connection with a switch module are
not listed above. In principle, such mezzanine cards can be installed without considering the interface
with other mezzanine cards. For details, see user's guides and manuals of the mezzanine cards and
CPU blades to be installed.)
