1/10G Base-T Autosensing Ethernet Port - NEC QX-S6648XP-6Q Installation Manual

Installation Guide
QX-S6600 Series Ethernet Switches
Caution:
Minimum bend radius of 40G QSFP+ Copper cable is 50mm. When not securing minimum bend radius of a

cable, there is damage of a cable or a possibility that performance deterioration forms. Don't bend a cable
below the minimum bend radius. Please refer to QSFP+ on Figure 10-4 (the right side) for a figure of the
minimum bend radius of QSFP+ copper wire cable.
10G SFP+ side minimum bend radius of 40G QSFP+/10G SFP+ Copper cable is 35mm. 40G QSFP+ side

minimum bend radius is 50mm. When not securing minimum bend radius of a cable, there is damage of a
cable or a possibility that performance deterioration forms. Don't bend a cable below the minimum bend
radius. Please refer to Figure 10-3 for 40G QSFP+/10G*4 SFP+ change copper wire cable. Please refer to
Figure 10-4 for a figure of the minimum bend radius of 40G QSFP+/10G*4 SFP+ change copper wire cable.

10.1.6 1/10G Base-T autosensing Ethernet port

QX-S6648XT-6Q has 1/10G Base-T autosensing Ethernet ports.
Connector type
Port transmission rate
Transmission medium and max
transmission distance
Compatible standards
To avoid interference between cables, layer cables as follows:
Use category-6A or above cables and connectors.

Do not bundle cables in their first 20 m.

Separate power cords 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 are preferably not adjacent, for example:
1) 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.
2) If the device connects to two distribution frames, connect port 1 on the device to port 1
