Note 1:
Support for the stacking feature depends on the installed firmware. To
determine whether your switch supports stacking, see the
Application Guide
for your
specific switch and firmware version.
Note 2:
If service required is due to a stacking error, either the Master or Member
LED may be steady green, depending on the last known good state, or both LEDs
may be steady green to indicate a general stacking error.
