Figure 77: CPAK Adapter Module
Apart from physical hosting the QSFP+ transceiver module, the CPAK adapter provides following
functions:
• Provide inrush control, voltage regulation, and power filtering.
• Manage the CPAK and QSFP+ low-speed signals, and register map.
• Signal conditioning retimers.
• Terminate unused channels (channels 4 to 9).
For enabling the CPAK adapter and QSFP module, you need to configure the 1X40 breakout interface with
the hw-module location rack/slot/CPU0 command in global configuration mode. Example:
Router# configure terminal
Router(config)# hw-module location 0/1/CPU0 port 3 breakout 1xFortyGigE
Router(config)# commit
2x40G Breakout mode is not supported.
Note
The CPAK adapter module supports only the following 40GE QSFP+ transceiver modules:
• QSFP-40G-LR4
• QSFP-40GE-LR4
• QSFP-40G-ER
