Functions

Table 3 describes functions of the ES5D21Q02Q00.

**Table 3** Functions
Function	Description
Basic functions	Provides two 40GE QSFP+ optical ports for data access and line-rate switching. Each 40GE port can be split into four 10GE ports. NOTE: When the card is installed on the S6720-SI, the restrictions are as follows: The four 10GE SFP+ ports on the front panel cannot be used simultaneously with ports on the ES5D21Q02Q00 card. If the ES5D21Q02Q00 card is installed in the switch, only the ports on the front panel can be used by default. V200R011 version: To use the port on the card, run the set device port-on-card enable command. Then the four 10GE SFP+ ports on the front panel cannot be used. V200R012 and later versions: To use the port on the card, run the undo set device port-config-mode port-on-board enable command. Then the four 10GE SFP+ ports on the front panel cannot be used.
Hot swapping	Supported
Service port stacking	Ports on the card can be used as stack ports. NOTE: A 40GE port cannot be used as a stack port after it is split into four 10GE ports.

1. Two 40GE QSFP+ optical ports

40GE QSFP+ optical port

A 40GE QSFP+ optical port sends and receives service traffic at 40 Gbit/s and can be split into four 10GE ports. After a split, the 40GE QSFP+ optical port needs to be connected to a remote device using a 1-to-4 QSFP+ fiber (with matching optical modules), a 1-to-4 QSFP+ AOC cable, or a 1-to-4 QSFP+ copper cable. Table 5 lists the attributes of a 40GE QSFP+ optical port.

Both optical ports on the ES5D21Q02Q00 support only QSFP+ optical modules, QSFP+ AOC cables (10 m; QSFP+ to QSFP+ or QSFP+ to 4*SFP+), and QSFP+ copper cables (1 m, 3 m, and 5 m; QSFP+ to QSFP+ or QSFP+ to 4*SFP+).

Connector type	LC/MPO
Optical attributes	Depend on the optical module used (see 40GE QSFP+ Optical Modules)
Standards compliance	IEEE 802.3ba
