Preface
Thank you for purchasing the N8405-024F Blade Enclosure (SIGMABLADE-H).
The blade enclosure houses modules such as CPU blades, switch modules, pass-through cards, EM
cards, power units, and fan units to integrate their functions and to allow CPU blades to function as
servers.
Read this guide before you start using the blade enclosure. Also, refer to the "User's Guide" and
"Startup Guide" that come with the SIGMABLADE series.
* This guide can be used for the Slot Cover (Power Unit) N8405-036, Slot Cover (Fan) N8405-037 and the Slot Cover (Switch
Module) N8405-038 as well.
Overview
This blade enclosure can integrate a maximum of 16 servers' functions into one blade enclosure by
housing a maximum of 16 CPU blades and 8 pass-through cards or switch modules in a case of 10U
(about 445mm).
N8405-025F Power Unit (option) can be optionally added to the power units that are equipped as
standard. A maximum of six power units can be mounted. The power units support the N+1
redundant mode or the N+N redundant mode. These modes allow for continuous operation even if
one power unit or one power unit system fails. The EM card on the blade enclosure allows for
management of fan units, power units, and CPU blades.
You can use remote KVM of CPU blades by connecting the LAN connecter on an EM card to an
external console (such as a PC).
