SM User Manual January 2004
Software Release 4.1
Power Control
In Release 4.1 and later releases, the operator selects either
• Low to set the SM to operate at 18 dB less than full power to reduce the possibility of
self-interference with a nearby module.
• Normal to allow the SM to operate at full power.
Selection of Low can cause the SM to drop an active RF link to a module that is
relatively far from the low-power SM. If a link is dropped when Power Control is set to
Low, the link can be re-established by only Ethernet access.
See Power Reduction to Mitigate Interference on Page 59.
Figure 37: Configuration screen, continued
As shown in Figure 37, the Configuration page continues with the following parameters:
Community String
The operator specifies a control string that allows an SNMP NMS (network management system) to
access MIB information about this SM. No spaces are allowed in this string. The default string is
Canopy.
Accessing Subnet
The operator specifies the NMS server that is allowed to access MIB information from the module.
The following two types of information must be entered:
• The network IP address in the form xxx.xxx.xxx.xxx
• The CIDR (Classless Interdomain Routing) prefix length in the form /xx (for example,
198.32.0.0/16 where /16 is a subnet mask of 255.255.0.0).
NOTE: For more information on CIDR, execute an Internet search on “Classless
Interdomain Routing.”
The default treatment is to allow all networks access (set to 0).
