1. Two 10GBASE-T RJ45 electrical ports

10GBASE-T RJ45 electrical port

The two 10GBASE-T RJ45 electrical ports on the ES5D21X02T01 can only transmit services at 10 Gbit/s and cannot work at 100 Mbit/s or 1000 Mbit/s. Category 6A shielded twisted pair (STP) cables are recommended for the ports. Table 5 lists the attributes of a 10GBASE-T RJ45 electrical port.

**Table 5** Attributes of a 10GBASE-T RJ45 electrical port
Attribute	Item
Connector type	RJ45
Working Mode	10 Gbit/s
Standards compliance	IEEE802.3an, IEEE802.3az

Table 6 lists the maximum transmission distances of different cables on 10GBASE-T RJ45 ports.
