Defining the DTC

A name for the DTC, up to eight alphanumeric characters, beginning with a letter. Each DTC configured on the system must have a unique name.

The local station address of the DT C. The HP 2345B (DTC 48) station address is printed inside the front cover. The HP 2340A (DTC 16) station address is printed on the label located on the upper right-hand corner of the back panel of the DTC. The HP J2070A (DTC 72MX) and J2062A/J2063A/J2064A (DTC 16iX/16MX/16RX) station address is printed on the label located at the lower center of the back panel of the DTC.

A typical LAN address looks like: 08-00-09-1A-11-11.

For DTC 16RX access to an HP 3000 in an MPE/iX host-based management environment, use the value 00-00-00-00-00-00 as the DTC 16RX LAN address. Configuration of the DTC 16RX is done on the HP 9000 host using DTC 16RX Manager.

A fully qualified node name of the DTC, in the form nodename.domain.organization, where each field can contain 16 or fewer characters (alphanumeric, underscores, or hyphens). The first character of each field must be alphabetic.

Assign meaningful node names. For example, ACCTS.IXNET.ACCTG and PAY.IXNET.ACCTG are meaningful names for two nodes on the same Local Area Network (LAN) within the accounting department. One node (ACCTS.IXNET.ACCTG) is used by the accounts staff. The other node (PAY.IXNET.ACCTG) is used by the payables staff. The domain field is the same because the nodes belong to the same network. The organization field is the same because the nodes belong to the same internetwork.

The internet protocol (IP) address of the DTC. The IP address is optional. It is used if your HP 3000 is configured as part of a network and you want the DTC to be able to respond to PING/iX requests.

An IP address is made up of a network portion and a node portion. The address is formed as four fields of decimal numbers where each number is a value ranging from 000 to 255.

The following shows examples of three classes of IP addresses:

where nnn represents the network portion and xxx represents the node portion of the address. The class of the IP address is determined by the value of the left most group of nnn and has the following ranges:

Network and node portions of all zeroes or 255 are not allowed for DTC addresses. These are special values. All devices configured with the same network portion are considered to be on the same network. The node portion must be unique for all nodes on a network.

You can obtain a Class B or Class C IP address from:

For DTC 16RX access to an HP 3000 in an MPE/iX host-based management environment, the IP address of the DTC 16RX is configured using the DTC 16RX Manager on the HP 9000 host and not on the HP 3000. Any value entered for the DTC 16RX in NMMGR will be ignored.

The number and types of connector cards in the DTC. (The cards are also referred to as boards.) DTC 16 can have up to 2 asynchronous cards and 1 DTC/X.25 Network Access card, DTC 48 up to 6 cards, and DTC 72MX up to 4 cards.

DTC 16iX/16MX/16RX has its two port connectors built directly onto its backplane for support of up to 16 asynchronous devices. It does not have removable cards; you do not specify the number or type of cards for a DTC 16iX/16MX/16RX.

The valid card types are:

For each DTC, logging class 1 logs catastrophic events and will always be enabled. Class 2 logs critical events; class 3 logs non-critical events; classes 4 and 5 log informative events and class 6 provides statistical information. It is recommended that you only enable classes 4 through 6 when you encounter problems, because they will generate and log a substantial number of events. The log files could use a significant amount of disk space.

Event logging classes do not apply for access to an HP 3000 in an MPE/iX host-based management environment using a DTC 16RX; any values entered in these fields for the DTC 16RX will be ignored.
