NOTE: 
•  As a best practice, use HPE QSFP+ transceiver modules, QSFP+ network cables, or QSFP+ to 
SFP+ network cables for the QSFP+ ports on the switch. The HPE QSFP+ transceiver modules, 
QSFP+ network cables, and QSFP+ to SFP+ network cables available for the interface modules 
are subject to change over time. For the most recent list of QSFP+ transceiver modules, QSFP+ 
network cables, and QSFP+ to SFP+ network cables available for the interface modules, contact
Hewlett Packard Enterprise Support or marketing staff. 
•  You can use a QSFP-40G-SR4-MM850 or QSFP-40G-CSR4-MM850 transceiver module to 
connect a QSFP+ port to four SFP+ ports. The QSFP+ transceiver module and SFP+ transceive
 
modules to be connected must be the same in specifications, including central wavelength and 
fiber type. 
 
For more information about HPE QSFP+ transceiver modules, QSFP+ network cables, and QSFP+ 
to SFP+ network cables, see HPE Transceiver Modules User Guide. 
1/10GBase-T autosensing Ethernet port 
The LSWM124XGT2Q interface module provides 1/10GBase-T autosensing Ethernet ports. 
Table 22 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, 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 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: 
{  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.
