Core routing blade overview
Two CR32-8 core routing blades are installed in device slots 7 and 8. Core routing
blades contain ASICs that allow switching between up to eight port blades. Core
routing blades connect to port blades through Fibre Channel backplane ports. Each
core switch blade provides 192 backplane ports for port blade connections. Each
core routing blade also has 64 front-end ports that are mapped to 16 QSFP
transceivers on the blade's front panel. These transceivers can create ICL
connections for up to nine separate switches in a full-mesh topology and 12
switches in a core-to-edge topology. Each transceiver provides four 32 Gbps FC
links for a total of 128 Gbps per connection. This core switch blade is compatible
only with the SAN512B-6.
Core routing blades contain the following LED indicators:
v
Green blade power LED
v
Amber blade status LED
v
Bicolor green/amber QSFP port status LEDs
For details on interpreting LED operation, refer to “Interpreting core routing blade
LEDs” on page 77.
CR32-8 port numbering
The following illustration shows how ports are numbered and port trunking
groups are arranged on the blade.
