It supports VLAN division based on 802.1Q and QinQ; and QoS setting based
on port, 8021.1P and TOS which can be divided into priorities. These three QoS
are enabled by default and configured with the recommended priority to ensure
the normal monitoring and E1/T1 signal transmission priority, i.e. monitoring
uses the highest priority (7); UPLINK port and optical port use priority (4);
layer-2 E1/T1 uses priority (6); layer-3 E1/T1 uses DSCP priority 184 (0xB8);
Ethernet service uses the lowest priority (0). If priorities need to be modified,
E1/T1 service and monitoring priorities are recommended to be set to 6, 7;
common Ethernet service priority is set to 0-5.
Ethernet electrical port uses RJ45 socket. Pin definition of RJ45 Ethernet
socket is shown in Table 2.2-4. Ethernet optical port can use dual-fiber SFP
optical module and the port labeled (
is for optical signal output, (
for input.
Also Ethernet optical port can use single-fiber optical module which has only
one optical interface. The wavelength of single-fiber module is its emission
wavelength, which is 1310nm or 1550nm.
Note that single fiber device with
the same emission wavelength cannot interwork. So when single-fiber
devices are interworked, the devices with matched emission wavelengths
should be used.
The user can choose different SFP optical module according to
the different transmission distance.

Tip: In auto-negotiation mode, Ethernet electrical port supports HP
auto-MDIX function, which can automatically detect the transceiver line
order of the network cable connected and make adaptions. So the port can
be used whether the Ethernet port is MDI or MDI-X and whether the
network cable used is crossover or straight-through.
