Defining the DTC Connector Cards (or Boards)
Connector cards
(also called boards) in the DTC allow terminals, printers, and other
serial devices to be connected to the DTC for communication with an HP
3000 Series 900.
For each connector card in a DTC, you must define the characteristics of
its ports for connection to terminals, printers, and other serial
devices. The following parameters are required:
Card Number The card number specifies which card in the DTC is
being configured.
DTC 16s allow 2 connector cards, labeled card # 0
and card # 1, with the third slot (card # 2)
reserved for a DTC/X.25 Network Access card. When
looking at the rear panel of the DTC, card # 0 is
located on the left, card # 1 is in the middle, and
card # 2 is on the right.
DTC 48s allow up to 6 connector cards, labeled card
# 0 to 5.
DTC 72MXs allow up to 3 connector cards plus a LAN
card that is preinstalled in slot 0; the connector
cards are labeled card # 1 through 3.
For the DTC 48 and 72MX, card # 0 resides at the
bottom of the DTC and card # 1 resides above it,
and so on.
Note that the DTC 16iX/16MX/16RX does not have
connector cards. Its port connectors are built
directly onto its backplane.
Direct or Modem You must specify whether a direct or modem
Connect connection is used for the ports in a card.Direct
connections are used for devices that reside near
the DTC. Modem connections are essential for
communications over telephone lines.
Port Number Each port on a connector card is assigned a number,
starting with port # 0 on the left most side of the
card.
Logical Device Each port needs a logical device
Number (LDEV) (ldev) number assigned to it, if the DTC is managed
by an HP 3000. The ldev number is used by MPE/iX
to designate devices. Devices with ldevs
permanently assigned to them are called nailed
devices.Printers and UPSs, as well as devices that
will be programmatically accessed, must be nailed
devices. Each nailed ldev number assigned in NMMGR
must be unique.
If the DTC management is PC-based (that is, managed
by an OpenView Windows Workstation), you may have
ports without ldev numbers assigned to them; hence
they are non-nailed devices. Non-nailed devices
have ldev numbers that are assigned from a pool of
available ldev numbers for the duration of the
device connection to the system. Terminals are
examples of non-nailed devices for PC-based
management.
Terminal and Printer Each port needs a profile assigned to it.A profile
Profiles defines a set of characteristics for a terminal,
printer, or another serial device. A profile can
be of five types: a terminal profile,a PAD
terminal profile,a printer profile,PAD printer
profile,or a host profile.Refer to chapter 7
"Terminal and Printer Profiles" for more
information on the profiles that are supplied in
the sample configuration file.
If the characteristics provided in the sample
profiles are different from those required by the
terminals and printers connected to your DTCs, then
you can define new profiles.
It is suggested that you use default profiles
TR10D96 for direct connect terminals and PR18D96
for direct connect printers or PR22D24 for HP
printers with status checking. For PAD terminals
and printer, use the defaults TR24PAD and PR26PAD,
respectively. For UPSs, use the default profile
UP10D12.
The name of the profile can be up to eight
characters long and must start with a letter,
followed by letters and numbers. At any one time,
up to 1024 profiles can be configured per system.
