1 Is the checksum error a hard error?
The first occurrence of a checksum error doesn't determine whether the error is a hard error or a soft
error. If the error is persistent (doesn't disappear after a reboot) and is accompanied by continuous
and consistent checksum error messages in the system log, it might be a temporary hard error.
If any hardware has been changed recently, and this switch is a modular chassis, try reseating the
affected blade.
