Core Routing Blades
Core Routing Blade Overview
Two CR64-4 core routing blades are installed in device slots 5 and 6. Core routing blades contain ASICs that allow
switching between up to four-port blades. Core routing blades connect to port blades through Fibre Channel backplane
ports. Each core routing blade provides 96 backplane Gen 7 FC ports for the port blade connection. Each core routing
blade also has 32 front-end ports that are mapped to 8 QSFP transceivers on the blade's front panel. These transceivers
can create inter-chassis link (ICL) connections for up to 9 separate directors in a full-mesh topology and 12 directors in a
core-to-edge topology. This core routing blade is compatible only with the Brocade X7-4.
Core routing blades contain the following LED indicators:
•
Green blade power LED
•
Amber blade status LED
•
Bicolor green/amber QSFP port status LEDs
For details on interpreting LED operation, see Interpreting Core Routing Blade LEDs.
