VISM Card Did Not Become Active
Investigate the following possible causes for a VISM card that does not become active:
• An E1 card is inserted in a slot where a T1 card was present, or a T1 card is inserted in a slot where
an E1 card was present, resulting in configuration mismatch.
• The minimum number (five) of DSPs failed to download.
• A front card type does not match the back card type—if the front card is T1 and the back card is E1,
or the front card is E1 and the back card is T1.
• The VISM card MIB image version does not match the PXM disk MIB image version.
