LAN
9000 Local Area Network
(UP
2285A)
LAN
9000
is a
bundled
software
and
hardware
product that provides high performance local area
networking of
HP
9000 Series
500
computers running the
HP-UX Operating System. Its implementation is
Ethernet· Version
1.0
and
it is essentially transparent to
its users. In addition to its multi-user, multi-service
and
multi-connection capabilities, it provides:
Remote File Access - access to directories, data files,
special files
and
peripherals across the network.
Network File Transfer - transfer of files within the
network.
Remote
Process Management - starting or stopping
processes
on
systems throughout the network.
Interprocess Communication - communication between
simultaneously
running
processes. LAN
9000
can link
processes local to
one
machine or remotely across the
network while maintaining the same user interface.
• Ethernet

a
registered
trademark
of
Xerox
Corporation.
Features
• Coax cable with baseband signalling.
•
10
Mbps data signalling rate.
• Minimum separation between nodes
is
2.5m.
• Nodes can be
up
to
SOm
from the coax cable.
• Masterless protocol, Carrier-Sense Multiple Access with
Collision Detection (CSMNCD).
• Up to
SOOm
segment coax length
and
up
to
100
nodes
per
segment.
• Supports
broadcast
and
multicast addressing.
• User-executable diagnostics which can be
run
simultaneously with other network services.
Operation
LAN
9000
consists of a self-contained Ethernet
Interfacing
Unit (LAN Unit), a transceiver branch cable, a
transceiver, LAN
9000
software
and
a dedicated HP-IB
interface cable (HP 27110A). LAN
9000
is microprocessor
based
and
is downloaded with link protocol software
over the
HP-IB interface from the host CPU (see Figure 1
for the physical configuration).
When
addressed by another node
on
the network,
the
HP
228SA
LAN Unit receives packets
and
checks the
accuracy of data before passing the packet
on
to the host
CPU. For transmission of packets, the host transfers the
packet to the LAN
Unit over the HP-IB cable
and
the
LAN
Unit in
turn
transmits the packet onto the network
according to the Network Access Protocol.
To increase the length of the transceiver branch,
up
to
two additional IS-metre cables can be ordered
(HP Part
No. 1150-1629).
The Ethernet cable installed
must
meet Ethernet
Version
1.0, Sept.
30,
1980,
Section 7.3 specifications.
HP
Computer Supplies Operation has two cables available:
Ethernet Cable
(92179E)
and
Non-Conduit Ethernet Cable
(92179F).
The
92179F
is
made
with a Teflon
t
outer jacket
and
Teflon dielectric. This cable can be installed in air
plenums. The
97179E
cable
must
be installed in cable
trays or conduit.

Local Area Network Installation Kit
(UP
28656A)
This kit provides the connectors
and
tools
needed
to
install the Ethernet standard coax cable
and
to connect
the transceivers
used
in the LAN
9000
product. It is
recommended that
the
installation kit be supplied for
every network
and
not
for every
228SA
ordered.
The kit includes:
