Configuring a LAN Node

Configure a LAN Network Interface

You need not enter the following items as NMMGR will fill these in:

•Class A, B, C

•Leading zeros for the network and node portion of the IP address.

HP assigns the network portion (initial nine digits) of IP addresses from ARPA Class C, though your addresses may also be of Classes A or B. The complete formats are:

Class A nnn xxx.xxx.xxx

B nnn.nnn xxx.xxx

C nnn.nnn.nnn xxx

Where: nnn = the network portion of the IP address and

xxx= the node portion of the IP address.

For Class C, the node portion of the IP address must be between 001 and 254.

If you are adding your NS 3000/iX node to an existing network, the network portion of each node’s IP address should be the same. You will have to find out what this is, and use it in the network portion of the IP address of your NS 3000/iX node. Also, you will need to know the node portions of the IP addresses of each of the nodes (usually they will be numbered sequentially, such as 001, 002, and so on), so that you can specify a unique node portion for the IP address of your node. If you have a network map, it should provide a record of such items as the node name and IP address of each node. If there is no record, and if you want to find out each node’s IP address, you will have to issue the following command (NM capability required) on each of the nodes:

NETCONTROL NET=NIname;STATUS

One of the lines of output from this command tells you what the complete IP address is for that node; the last three digits are the unique node portion of the class C address.

IP subnet mask

An IP subnet mask is specified in the

 

same format as an IP address. The

 

32-bit mask is grouped in octets

 

expressed as decimal integers and

 

delimited by either a period (.) or a

 

space. An IP mask is used when

 

configuring subnetworks. The mask

 

identifies which bits of an IP address

 

will be used to define a subnetwork. To

 

determine these bits, you first need to

 

estimate how many subnetworks and

 

nodes per subnetwork you need. See

 

Chapter 2 , “Networking Concepts,” for

 

details on deriving an IP subnet mask.

E3000 MPE/IX, E3000/IX specifications

The HP E3000 series, particularly the E3000/IX and E3000 MPE/IX, represents a significant milestone in the evolution of business computing, developed by Hewlett-Packard (HP) during the late 1970s and early 1980s. These systems were designed to provide robust, reliable, and efficient operation for mid-sized businesses, leveraging the power of the MPE (Multi-Programming Executive) operating system.

One of the main features of the HP E3000 series is its multitasking capability. MPE/IX allows for multiple applications to run concurrently, maximizing the utilization of system resources. This is particularly beneficial for organizations that require simultaneous access to various business applications, ensuring enhanced productivity and efficiency.

The HP E3000/IX architecture is built on a powerful 16-bit or 32-bit microprocessor, enabling it to handle substantial workloads. The system architecture is known for its modular design, which allows for easy upgrades and customization. This flexibility is essential for businesses that need to adapt to changing demands without overhauling their entire computing infrastructure.

Another notable technology incorporated into the HP E3000 series is its support for a range of storage solutions. The E3000 systems were compatible with various disk drives, providing organizations with options for data storage that matched their performance and capacity requirements. Additionally, they featured advanced data management capabilities, such as built-in backup and recovery systems, ensuring that critical business information remained secure and accessible.

Beyond hardware capabilities, HP E3000/IX and MPE/IX systems provide extensive programming support. They included tools for developing custom applications, with support for languages such as COBOL, BASIC, and FORTRAN. This versatility made it easier for businesses to tailor their software solutions to their specific needs, enhancing operational effectiveness.

Networking capabilities were also a significant innovation of the E3000 series. The systems offered robust support for various networking protocols, allowing for seamless integration with other computing environments. This facilitated communication and collaboration within an organization, as well as with external partners and clients.

In summary, the HP E3000/IX and E3000 MPE/IX systems were pivotal in delivering reliable computing power to mid-sized enterprises. With their multitasking operating system, modular architecture, advanced data management, and programming support, these systems provided an adaptable and comprehensive solution for evolving business needs. The legacy of the E3000 series is evident in how it paved the way for modern enterprise computing, focusing on flexibility, scalability, and efficiency.
