Configure the NIM’s IP Address
The HSS' NIM acts as an interface between the serial devices connected to the
HSS and the network. The NIM is referred to as a "tunneling device," because
its function is to pass - or tunnel - serial data through a network. As such, the
NIM requires a valid IP address.
IMPORTANT:
(1) The NIM cannot be addressed greater than 250. (2) The
ground (G) switch must remain in the ON position. (3) The BRAIN switch,
when set to the OFF position, allows an IP address to be configured when
using a NIM/FIM. Set the BRAIN switch to ON when using a NFM.
The NIM features automatic IP addressing. It
obtains the first three octets of its network
address from an HSM broadcast (a network
service called NIM Broadcast). The last octet
comes from the NIM Tunneling IP Address
block (located in the HSS to the left of the
NIM). The last octet is configured by placing
each of the DIP switches on the address block
either in the ON or OFF position. The address
is calculated by adding up the bits that are
OFF. The example at right shows the NIM
addressed at 208. The 128, 64, and 16 switches
have been placed in the OFF position (128 + 64
+16 = 208).
