CE88-D24S2CQ-U (24-Port 25GE/16G FC (SFP28) and 2-Port 40GE/100GE (QSFP28) Interface Card)
Version Mapping
Table 5-29 describes the mapping between the CE88-D24S2CQ-U card, switch models, and software versions.
Card Overview
The CE88-D24S2CQ-U card can be install in any slot of the CE8860-4C-EI or CE8861-4C-EI chassis.
Figure 5-14 shows the appearance of the CE88-D24S2CQ-U card.
Functions and Features
Table 5-30 describes functions and features of the CE88-D24S2CQ-U card.
Function and Feature |
Description |
---|---|
Basic function |
Provides data packet processing and traffic management on 24 25GE/10GE SFP28 optical ports and two 40GE/100GE QSFP28 optical ports. The 24 25GE/10GE SFP28 optical ports can be configured as 24 FC interfaces (supporting rates of 4 Gbit/s, 8 Gbit/s, and 16 Gbit/s). |
Port split |
Each QSFP28 optical port can be split into four 25GE ports or four 10GE ports. Such 25GE or 10GE ports cannot work at 1 Gbit/s. |
Hot swap |
Supported |
Service port stacking |
Ports on the card can be used as stack ports. NOTE:
24 25GE/16G FC optical ports cannot be used for stack connections. |

Port use constraints |
The 24 25GE/16G FC (SFP28) optical ports of the CE88-D24S2CQ-U work at 25 Gbit/s by default and do not support GE/10GE auto-sensing. You can set the port speed to 10 Gbit/s or 1 Gbit/s using the port mode 10g or port mode ge command. The 24 25GE/16G FC (SFP28) optical ports are divided into six port groups, each of which contains four ports (1-4, 5-8, 9-12...21-24).
