Fabric OS 5.2.0a. Do not insert the F C4–48 blade into the 4/ 256 chassis
until the chassis is running Fabric OS 5.2.0a or later. After Fabric OS has

• Regarding port mirroring, the FC 4–48 is restricted to one F-port mirroring
allowed between shared areas for por ts 16–47. On the FC4–48, port
mirroring on ports 0–15 behaves the same as the FC4–32 blade.

To use the 4/256 SAN Director to attach to the System z envir o nment, use
the FC4–16 or FC4–32 Fibre Channel port blades.
• In a zoning configuration with members D and P, where P is greater than
or equal to 256, remove t hese configurations before d owngrading to an
earlier firmware version (5.1.x or 5.0.x). Otherwise, the downgrade will
