Card Status Maintenance
□ Description of Abnormal States of Cards and Restoration Operations
▪ Installed: Indicates that a card is virtually loaded but is not actually
inserted. This state occurs in two cases: 1) One card is installed virtually
for command learning or pre-configuration. 2) A card is inserted before but
is removed now.
▫ Restoration operation:
▪ None: Indicates that no card is inserted and no card is manually installed.
The slot is in the empty state. If a card is actually inserted but is in the
None state, remove the card and insert it again. If the card cannot be
restored to the normal state, a hardware fault may exist.
– Run the no install command to virtually delete the card of this slot,then
insert the card, and the device automatically identifies the card.
Ruijie(config)#no install 4/1 // 4/1 indicates the slot ID.
