Blade terminology and compatibility

CP blades

The control processor (CP) blade provides redundancy and acts as the main controller on the

Brocade Backbone. The Brocade DCX and DCX 8510 Backbone families support the CP8 blades.

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.

For more information on maintaining firmware in your Backbone, refer to Chapter 9, “Installing and

Maintaining Firmware”.

Core blades

Core blades provide intra-chassis switching and 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

Table 6 on page 45 identifies which port and application blades are supported for each Brocade

Backbone.

NOTE

The FR4-18i blade cannot coexist in the same chassis with an FX8-24 blade.

NOTE

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 a non-FCOE10-24 blade is detected

first, then any subsequently-detected FCOE10-24 blades are faulted. Blades are powered up

starting with slot 1.

The maximum number of intelligent blades supported on a Brocade DCX or DCX 8510-8 is eight.

The maximum number of intelligent blades supported on a Brocade DCX-4S or DCX 8510-4 is four.

Table 7 lists the maximum supported limits of each blade for a specific Fabric OS release. Software

functions are not supported across application blades.
