1/10GBase-T autosensing Ethernet port
The HP 5900AF-48XGT-4QSFP+ and HP 5900AF-48XGT-4QSFP+ TAA switches have 1/10GBase-T
autosensing Ethernet ports.
Table 19 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, HP recommends that you layer cables as follows:
• Use category-6A or above twisted pair 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.
LEDs
System status LED
The system status LED shows the operating status of the switch.

LED mark Status Description
SYS
Steady green The switch is operating correctly.
Flashing green The switch is performing power-on self test (POST).
Steady red
The system has failed to pass POST or has problems such as
fan failure.
Flashing red Some ports have failed to pass POST.
Off The switch is powered off or has failed to start up.
