1/10GBase-T autosensing Ethernet port
Every S5820V2-52Q switch has 1/10GBase-T autosensing Ethernet ports.
Table 18 1/10GBase-T autosensing Ethernet port specifications
Item Specification
Connector type RJ-45
Port transmission rate 1/10 Gbps, full duplex, MDI/MDI-X autosensing
Transmission medium and max
transmission distance
• 55 m (180.45 ft) over category-6 unshielded twisted pair cable
• 100 m (328.08 ft) over category-6 shielded twisted pair cable
• 100 m (328.08 ft) over category-6A or above twisted pair cable
Compatible standards
• IEEE 802.3ab
• IEEE 802.3an
To avoid interference between cables, H3C recommends that you layer cables as follows:
• Use category-6A or above cables and connectors.
• Do not bundle cables in their first 20 m (65.62 ft).
• Separate power cables and twisted pair cables at and around the distribution frame.
• For ports adjacent to one another on the device, the peer ports on the distribution frame is
preferably not adjacent, for example:
{
If the device connects to one distribution frame, connect port 1 on the device to port 1 on the
distribution frame, port 2 on the device to port 3 on the distribution frame, and port 3 on the
device to port 5 on the distribution frame.
{
If the device connects to two distribution frames, connect port 1 on the device to port 1 on
distribution frame 1, port 2 on the device to port 1 on distribution frame 2, and port 3 on the
device to port 2 on distribution frame 1.
