Huawei MA5683T is an aggregation Optical Line Terminal (OLT), it supports up to 6 service slots and can support a maximum of 12,000 subscribers (GPON). MA5683T has GICF/X2CS Uplink Board available for selection, and two power slot redundancy for DC power input. Ethernet link aggregation increases link bandwidth by bundling multiple physical links to form a logical link. Link aggregation can work in manual mode or Link Aggregation Control Protocol (LACP) mode. In manual mode, you must manually create an Eth-Trunk and add member interfaces to the Eth-Trunk. As shown in Figure 1, SwitchA and SwitchB are connected to the networks of VLAN10 and VLAN20, respectively, via Ethernet links, and there is a large amount of data traffic between SwitchA and SwitchB. Link aggregation has the following advantages:. Original operating mode: Two S5700s were configured with Eth-Trunk1, and the ports of the three lines that need to be communicated were added to Eth-Trunk1. Set the port to access to allow the corresponding VLAN to pass; so that the two floors of the network can communicate normally In this way. And there are two link aggregation types. In LACP mode, there are active and backup links and backup links are used for redundancy. For this example, we. Link Aggregation is a technology defined in IEEE 802. It enhances bandwidth, provides fault tolerance, and allows load balancing between connected devices. Key benefits of link aggregation: Higher.

Are the protection parameters set correctly (trip value, trip time)? Is the assigned protection function blocked? Is the protection function´s trip signal routed to the Trip-Manager of the correct switchgear? Is the trip signal of the switchgear . Master trip relay or lockout relay, also known by ANSI code 86, holds a significant position as an intermediator between the protection relay and control points, even though it is not self-equipped with fault sensing capabilities. The master trip relay can operate as a hub of multiple protection. Since protection relays can be expensive, it is not advisable to connect them directly to the trip coil. if the fault detected by any of the protection relay means at the same time the protection relay trips the associated circuit breaker through the mater tripping relay circuits.
