Card Overview
The CE88-D24S2CQ card can be install in any slot of the CE8860-4C-EI, CE8861-4C-EI, or CE8868-4C-EI chassis.
Figure 5-11 shows the appearance of the CE88-D24S2CQ card.
Functions and Features
Table 5-23 describes functions and features of the CE88-D24S2CQ card.
Function and Feature |
Description |
---|---|
Basic function |
Provides data packet processing and traffic management on 24 10GE/25GE SFP28 optical ports and 2 40GE/100GE QSFP28 optical ports. |
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:
SFP28 ports that have GE copper modules, GE optical modules, 10GE optical modules, 10GE high-speed cables, or 10GE AOC cables installed cannot be used for stack connections. |

Port use constraints |
The 24 10GE/25GE SFP28 optical ports on the CE88-D24S2CQ card of CE8868EI work at 10 Gbit/s by default. You can set the port speed to 1 Gbit/s using the port mode ge command. After the corresponding license is loaded, you can run the undo port mode 10g command to set the interface to work at the rate of 25 Gbit/s. In addition to CE8868EI, the 24 10GE/25GE SFP28 optical ports of a CE88-D24S2CQ card work at 25 Gbit/s by default. 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 10GE/25GE SFP28 optical ports are divided into 6 port groups, with four ports in each group (1-4, 5-8, 9-12...21-24).

Applicable cables NOTE:
After a CE88-D24S2CQ card is installed on the CE8860EI, 10GE/25GE SFP28 optical ports on the card do not support SFP-25G-SR optical modules. |
When the port works in GE or 10GE mode, it can use:
|
When the port works in 25GE mode, it can use:
NOTE:
The port supports the SFP28 to SFP28 AOC cable only when FEC is disabled on the remote port. When an SFP28 to SFP28 high-speed cable is installed on the port:
