Configuring Slot Priority

Note

Note

This procedure only applies to VSP 8600 Series.

About this task

Configure slot priority to specify which slots you want to shut down if there is insufficient power available in the chassis. By default, power is available to all slots, and the slots have the following priority:

  • Slots 1, 2, SF1, SF2, and SF3 must always be Critical so you cannot configure them.

  • Slots 3-8 are High by default, but you can configure any of them to Low.

Note

Note

Power is always supplied to critical slots first which are the CP modules, SF modules, and fan trays.

The slot with the lowest priority shuts down first. Slots with the same priority shut down in descending order (highest slot number first) and interface slots shut down before CP, SF modules, and fan tray slots.

For example, if slot 3 has a low priority and slots 4 and 5 have a high priority, the slot shutdown priority is as follows: 4, 5, 3. Slot 3 has the lowest priority because it was configured as low so it would be shut down first. Slots 4 and 5 have the same priority, but slot 5 shuts down before slot 4 because slot 4 has a higher slot number.

Procedure

  1. Enter Global Configuration mode:

    enable

    configure terminal

  2. Configure slot priority:

    sys power slot-priority <3–8> {high|low}

Example

Switch:1>enable

Switch:1#configure terminal

Configure slot priority to determine that slot 3 has a low priority if insufficient power is available for all modules:

Switch:1(config)#sys power slot-priority 3 low
