Description

1. Replace when Sangfor aServer NIC needs to be upgraded and replaced (gigabit NIC is upgraded to 10 Gigabit NIC).
2. When the number of existing NICs of the Sangfor aServer machine is small, which does not meet the best practice, it is necessary to add NIC.
3. When the NIC of the Sangfor aServer machine fails, the NIC needs to be replaced.
4. For non-aServer, you need to contact the server vendor, and the personnel of the corresponding vendor will operate and maintain it. Sangfor employees are not allowed to operate directly.

Precautions

1. Please ensure that the NIC is in the compatibility list when upgrading or adding a NIC.
2. It is recommended to use a NIC with the same model parameters as the original NIC for replacement.

Prerequisites

1. Confirm the compatibility of the NIC. Please contact Sangfor technical support for evaluation if it cannot be determined.
