Which Cards of the N18000 Will Be Powered Off First When the Power Is Insufficient and What Is the Basis?

1. The N18000 is powered by the intelligent power supply, which allows configuring power supply priority for cards, controlling the power-on and power-off of cards, and reading the operating temperature, input voltage, and other information of the power supply.

2. The power supplies of cards have different priorities. A card with a higher priority is powered on prior to that with a lower priority and is powered off later than that with a lower priority. The default power supply priority of cards is as follows: supervisor module > FE card > VSL card > other cards. For cards of the same type, a card with a smaller slot ID has a higher priority than that with a larger slot ID. You can configure the power supply priority in the system running phase. This function ensures that cards with a higher priority are powered on first in the next startup and power-on. The command for configuring the power supply priority of cards is as follows:

[Command] power priority [switch devid] slot slotid prio

[Parameter Description] switch devid: Specifies the ID of the chassis, to which the card slot for which the power-on and power-off priority is to be configured belongs. It is supported only in VSU mode. The default value is the local chassis ID.

slot slotid: Specifies the slot ID of the card to be configured. The value is the range of card slot IDs.

prio: Specifies the priority of a card to be configured. The value ranges from 1 to 16. 1 indicates the lowest priority and 16 indicates the highest priority.

[Usage Guide] This command is used to change the default power supply priority of VSL cards and other cards. FE cards can only use the default priority.

[Configuration Example] Change the priority of the card in slot 3 of the N18010 to 10.

Ruijie(config)#power priority slot 3 10
