NOTES:

CAUTION!
Power requirements affect the recommended maximums for power cord length
feeding the CMMmicro or CMM4. See the dedicated user guide that supports
the CMM that you are deploying. 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.
2X Operation
A General tab option in both CSM 130s and hardware series P9 and greater CSM 120s provides
double the aggregate throughput for SMs that are nearer than half of the maximum typical range
from the AP. The requirements of this feature are as follows:
• The AP must be a CAP 130 (Advantage AP).
• The SM must be near the AP, roughly half the range of 1X.
• The SM must be of the P9 hardware series or later and enabled for hardware scheduling. See
Designations for Hardware on Page 425.
• The 2X Rate parameter in the SM must be set to enabled. This is the default setting.
