CE88-D24T2CQ (24-Port GE/10GBASE-T (RJ45) and 2-Port 40GE/100GE (QSFP28) Interface Card)
Version Mapping
Table 5-15 describes the mapping between the CE88-D24T2CQ card, switch models, and software versions.
Card Overview
The CE88-D24T2CQ card can be install in any slot of the CE8860-4C-EI, CE8861-4C-EI, or CE8868-4C-EI chassis.
Figure 5-8 shows the appearance of the CE88-D24T2CQ card.
Functions and Features
Table 5-16 describes functions and features of the CE88-D24T2CQ card.
Function and Feature |
Description |
|---|---|
Basic function |
Provides data packet processing and traffic management on 24 GE/10GBASE-T RJ45 electrical 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. NOTE:
The two QSFP28 ports are independent, and each can be configured as four 10GE or 25GE ports. |
Hot swap |
Supported |
Service port stacking |
Ports on the card can be used as stack ports. |
