Core Routing Blades
Core routing blades allow switching between the port blades.
Two CR32-4 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 ports for 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 ICL
connections for up to nine separate directors in a full-mesh topology and 12 directors in a core-to-edge topology. Each
transceiver provides four 32G FC links for a total of 128G per connection. This core routing blade is compatible only with
the Brocade X6-4.
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

CR32-4 Port Numbering
The following figure shows how ports are numbered and how port trunking groups are arranged on the blade.

2. QSFP ports 0-3 (right to left)
3. Map of ports 2, 3, 6, and 7
4. Map of ports 0, 1, 4, and 5
QSFP ports are numbered from 0 through 3 along the bottom row from right to left and from 4 through 7 along the top row
from right to left. For information on supported QSFP transceivers, see
Installing Transceivers and Cables
.
Ports belonging to the same trunking groups are indicated with the same color border under the ports. These colors are
also applied to the port map labels on each blade to indicate ports belonging to the same trunking groups.
Each numbered QSFP port on the blade provides four 32 Gbps FC ports. The following table shows the mappings from
the numbered QSFP ports on the face of the core blade to the individual FC port numbers as shown by the
slotShow
command.
