You can establish extended ECC communication between two subracks without fiber connections through an Ethernet line. In this way, the U2000 Web LCT manages the equipment in a centralized manner.
Context
NOTICE: This operation may restore the settings of communication, and may interrupt services.
Procedure
- In the NE Explorer, select an NE and choose from the Function Tree.
- Select the Extended ECC Mode.
NOTE: - Auto mode: Establish an extended ECC connection automatically. Though this mode is convenient, extra connections will be established and the resource availability is low. It is recommended when there are less than four NEs. No extended ECC can be established automatically unless both the NEs between which an extended ECC is to be established are set to the automatic mode.
- Specified mode: Specifies that an extended ECC is to be established between the server and the client. The connection is highly reliable and the bandwidth availability is high. This mode is usually used to establish an extended ECC connection.
- For an NE, the two modes cannot be used at the same time to extend ECC.
Follow-up Procedure
After you complete the settings for one NE, you need to configure the settings for the opposite NE to enable the extended ECC communication. Note the following points:
- If you set Extended ECC Mode to Auto mode for an NE, configure the same settings for the opposite NE.
- If you set Extended ECC Mode to Specified mode for an NE, configure the same settings for the opposite NE. In addition, the roles of the two NEs must be different. That is, if an NE serves as the server, the opposite NE must be the client.
