Initialize NVRAM
Initialize NVRAM is set to clear any existing configuration from
nonvolatile random access memory (NVRAM). This initializes
the NVRAM prior to entering a configuration, and should be
done before loading a new configuration. The LMM status LED
will blink green to indicate that initialization is complete.
Disable Checksums
NOTE: This setting is for troubleshooting purposes ONLY. The
switch should NOT be set to this position during normal operation.
Disable checksums prevents a ROM checksum error from halt-
ing the module.
Compress NVRAM
The configured function blocks are moved to the
top
of mem-
ory; unconfigured or free blocks are moved to the
bottom
.
Address Setting
An LMM can have one of 32 addresses (0 to 31) on the module
bus. This address uniquely identifies the LMM to other INFI 90
devices. Determine the address for the LMM, and set
dipswitches 4 through 8 to the corresponding positions shown
in Table
NOTE: The address must be a unique address within a PCU. Nor-
mally, addresses 0, 1, and 31 are not used for an LMM since these
are reserved.
