IEEE 802.3 Ethernet Communication
ADDvantage-32 PLUS
8-9
DRIVE IP ADDRESS:
X***: IP ADDR HI: Highest octet of the DRIVE IP ADDRESS. Range 1-255, default = 10
X***: IP ADDR HM: High Middle octet of the DRIVE IP ADDRESS. Range 1-255,
default = 1
X***: IP ADDR LM: Low Middle octet of the DRIVE IP ADDRESS. Range 1-255,
default = 206
X***: IP ADDR LO: Low octet of the DRIVE IP ADDRESS. Range 1-256, default = 256
Each ADDvantage-32 PLUS drive on the network must have a unique IP address assigned via
X parameters shown above. Parameter IP ADDR LO may be set to a special value of “256” that
indicates the LOW OCTET of the IP address should be set to the DRIVE ID ADDRESS. The
ADDvantage-32 PLUS drive IP address may need to be changed from default values to meet
your specific company’s requirements. If not specified by your MIS or IT Department, the IP
address can be left at the default values. Be aware that duplicate IP Addresses on the network
will cause communication problems and failures!
DRIVE SUBNET MASK:
X***: MSK ADDR HI: Highest octet of the DRIVE SUBNET MASK – range 0-255,
default = 255
X***: MSK ADDR HM: High Middle octet of DRIVE SUBNET MASK – range 0-255,
default = 255
X***: MSK ADDR LM: Low Middle octet of DRIVE SUBNET MASK – range 0-255,
default = 0
X***: MSK ADDR LO: Lowest octet of the DRIVE SUBNET MASK – range 0-255,
default = 0
The Drive Subnet Mask is defaulted to 255.255.0.0. The values of the Subnet Mask may need
altered to match the specifics of your company’s network. Your MIS Department may specify
the IP ADDRESS CLASS and subnet range. The Subnet Mask will be 255.255.255.0 or
255.255.0.0 depending on your network topology. A class A network would be 255.0.0.0, a
class B network would be 255.255.0.0, and a Class C would be 255.255.255.0. Be aware that
incorrect or inconsistent subnet mask values will cause communication problems and failures!
A subnet mask divides a network into sub networks. For example, we use 255.255.0.0, which
is a Class B network. 255.0.0.0 would be Class A, and 255.255.255.0 is Class C. The
255.255.0.0 means that any device on a local network with 10.1.xxx.xxx can communicate with
any other device on the local network with a similar 10.1.xxx.xxx IP address and a similar
255.255.0.0 subnet mask. That is over 64,000 devices. A Class C subdivides this into 254
different networks containing up to 254 each. In any given subnet, a person can only talk to
253 other devices. Computer 10.1.207.213 cannot see a drive at 10.1.206.1 on the Class C
network, but could on a Class B. This will normally be 255.255.0.0 unless the customer
specifies otherwise. A subnet could be further divided; for example, 255.255.255.128,
