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
