Brocade Fabric OS Administrators Guide (Supporting Fabric OS v7.3.0) - Manual (Page 82)

The CP blades in the Brocade DCX and DCX 8510 Backbone families are hot-swappable. The CP8
blades are fully interchangeable among Brocade DCX, DCX-4S, DCX 8510-4, and DCX 8510-8
Backbones.
Brocade recommends that each CP (primary and secondary partition) should maintain the same
firmware version.
Core blades
Core blades provide intra-chassis switching and inter-chassis link (ICL) connectivity between DCX/
DCX-4S platforms and between DCX 8510 platforms.
• Brocade DCX supports two CORE8 core blades.
• Brocade DCX-4S supports two CR4S-8 core blades.
• Brocade DCX 8510-8 supports two CR16-8 core blades.
• Brocade DCX 8510-4 supports two CR16-4 core blades.
The core blades for each platform are not interchangeable or hot-swappable with the core blades for
any other platform. If you try to interchange the blades, they become faulty.
Port and application blade compatibility
The maximum number of intelligent blades supported is eight on an 8-slot chassis and four on a 4-slot
chassis. However, the maximum number of a specific blade type is limited.
The following table lists the maximum supported limits of each blade for a specific platform. Software
functions are not supported across application blades.

FCOE10-24 compatibility
The FCOE10-24 blade is not compatible with other application blades or with the FC8-64 blade in the
same chassis.
In the Brocade DCX 8510-8, the FCOE10-24 blade has the following additional restrictions:
• Only one FCOE10-24 blade is supported, and only in slot 1. Installing the FCOE10-24 in any other
slot is not supported, although this is not enforced by software.
• The FCOE10-24 blade can coexist only with the FC16-32 and FC8-32E blades. Any other port
blade types are faulted.
During power up of a Brocade DCX or DCX-4S Backbone, if an FCOE10-24 is detected first before
any other AP blade, all other AP and FC8-64 blades are faulted. If an AP blade or FC8-64 blade is
2 Not compatible with other application blades or with the FC8-64 in the same chassis.
3 Supported only in slot 1.
4 The hardware limit is enforced by software.
