4-3
Attribute
Meaning
FPGA Version
This field indicates the version of the field-programmable gate array
(FPGA) on the module. If you request technical support, provide the
value of this field.
FPGA Type
Where the type of logic as a subset of the logic version in the module as
manufactured distinguishes its circuit board, this field is present to
indicate that type. If you request technical support, provide the value
of this field.
PLD Version
This field indicates the version of the programmable logic device (PLD)
on the module. If you request technical support, provide the value of
this field.
Uptime
This field indicates how long the module has operated since power was
applied.
System Time
This field provides the current time. If the AP is connected to a CMM,
then this field provides GMT (Greenwich Mean Time). Any SM that
registers to the AP inherits the system time.
Last NTP Time Update
This field displays when the AP last used time sent from an NTP
server. If the AP has not been configured in the Time tab of the
Configuration page to request time from an NTP server, then this field
is populated by 00:00:00 00/00/00.
Ethernet Interface
This field indicates the speed and duplex state of the Ethernet interface
to the AP.
Regulatory
This field indicates whether the configured Region Code and radio
frequency are compliant with respect to their compatibility. For
example, you may configure a 5.4-GHz AP with a Region Code set to
United States and configure a frequency that lies within the weather
notch. This is a compliant combination, the radio properly operates,
and its Regulatory field displays Passed. If later you change its Region
Code to Canada, then the combination becomes non-compliant (since
frequencies within the weather notch are disallowed in Canada. In this
case, the radio ceases to transmit, and its Regulatory field displays an
error message.
Channel Center Frequency
The operating center frequency of the AP
Channel Bandwidth
The size in MHz of the operating channel
Cyclic Prefix
OFDM technology uses a cyclic prefix, where a portion of the end of a
symbol (slot) is repeated at the beginning of the symbol to allow multi-
pathing to settle before receiving the desired data. A 1/16 cyclic prefix
means that for every 16 bits of throughput data transmitted, an
additional bit is used.
