NOTES:
1. For 2.4- and 5.n-GHz modules.
CAUTION!
Power requirements for modules that run hardware scheduling affect the
recommended maximums for power cord length feeding the CMMmicro. See
Table 50 on Page 347. However, the requirements do not affect the maximums
for the CMM2.
Packets that have a priority of 4 to 7 in either the DSCP or a VLAN 802.1p tag are
automatically sent on the high-priority channel, but only where the high-priority channel is
enabled.
