1. Eight 10GBASE-T RJ45 ports

10GBASE-T RJ45 port

The ES5D21X08T00 provides eight 10GBASE-T RJ-45 electrical ports. The first four electrical ports support only 10 Gbit/s. The last four electrical ports support only 10 Gbit/s in versions earlier than V200R019C00, and also support 100 Mbit/s and 1000 Mbit/s in auto-negotiation mode in V200R019C00 and later versions. When the ports work at 10 Gbit/s, Category 6A shielded Ethernet cables are recommended. Table 5 lists the attributes of a 10GBASE-T RJ45 port.

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

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

**Table 6** Maximum transmission distances of different cables on 10GBASE-T RJ45 ports
Cable Type (6-a-1 Bundle)	10GBASE-T RJ45 Port
Cat6A U/UTP	Not supported
Cat6A F/UTP	100 m
Cat6A STP	100 m
Cat7	100 m

6-a-1 stands for the six-around-one cable bundle mode, with one cable in the center and six cables bundled evenly around it.
