Small Form-Factor Pluggable (SFP) ports are slots that accommodate SFP transceiver modules. These ports connect network equipment using either fiber optic or copper cabling, depending on the type of SFP module. Quad Small Form-Factor Pluggable (QSFP) ports are high-speed, high-density network interfaces that accommodate QSFP transceiver modules. These ports are primarily used for data center, enterprise, and service provider environments where large amounts of data need to be transmitted quickly and efficiently.

With the C9600X-LC-56YL4C model:

• Do not use the SFP-H10GB-CUXX (1M/1.5M/2M/2.5M/3M/5M), SFP-H10GB-ACUXX(7M/10M) and SFP-10G-AOCXX (1M/2M/3M/5M/7M/10M) types of SFP modules from TE Connectivity, because the lever on these modules might interfere with other parts of the switch.

  

• On an SFP-10G-T-X SFP module, do not use an RJ-45 cable with a protection cap because the protruding cap might interfere with other parts of the switch.

  

• Do not use the SFP-25G-SR-S, SFP-10/25G-LR-S, SFP-10/25G-CSR-S on row C, the SFP module will be removed from the SFP port, if the lower card (underneath this card) is removed from the chassis of Cisco C9610R.
