Connecting UTP network cables to 5GE interfaces poses high risks and is not recommended. The
causes are as follows:
802.3bz requires that the ALSNR value for alien crosstalk between network cables be greater than 0,
but the standards for Cat5e and Cat6 unshielded twisted pairs do not specify the required ALSNR
value. Therefore, such cables may not meet the crosstalk requirement in 802.3bz, causing severe
problems such as continuous packet loss.
According the cabling specification TIA TSB-5021, using Cat5e and Cat6 cables for 5G poses high
risks.
Currently, no clear onsite testing or evaluation method is available for checking whether ALSNR of
cables conforms to 802.3bz.
If Cat5e and Cat6 unshielded twisted pairs do not meet the 5G requirement, you are advised to
replace them with shielded twisted pairs or reduce the rate of interfaces to 2.5G.
Connecting Antennas
Connect the antennas delivered in the installation accessory package of the AP to the 2.4G/5G
RF ports on the AP, tighten the nuts (with a torque of 0.8 N•m), and adjust antenna angles as
required.
Do not connect the antennas delivered in the installation accessory package of the AP to 5G antenna
interfaces. Otherwise, the AP and antennas may be damaged. The 5G antenna interfaces can be
connected only to remote antennas through feeder cables.
2.8 Connecting the Security Lock
There is a security slot on the device. You can lock the device to an immovable object to
prevent theft. The detailed procedures are as follows:
1.
Fasten the cable of the security lock to an immovable object around.
2.
Insert the security lock into the security slot and lock it.
