Hot to configure 2nd network port

Hi , I do have a very old 712/80 workstation of HP with HP Unix 9.05, The machine is connected to the network via LAN-AUI port thru AUI to BNC transceiver & one more RJ 45(LAN-TP) port is vacant on the system, Can I connect/configure a netwrok printer to the RJ-45 port.
One more card is Installed in my system with RS232 attachement which is connected to other network thru a Y cable & AUI to BNC transceiver
pls guide me step by step procedure to assign IP add to RJ45 port, If it is possible.
Thanks in advance
Nitin

Re: Hot to configure 2nd network port

This system and OS is much more than 10 years old - hard to remember.

IIRC you can either use the RJ45 or BNC connector, not both.

Hope this helps!

Re: Hot to configure 2nd network port

I found this information:


"...
The workstation has builtâ in ThickNet LAN AUI and TP (Twisted Pair) connectors
for the 802.3 (ETHERNET) network. Connections to ThinLAN networks require an
external transceiver. The workstation automatically selects the correct network set-
ting."

Hope this helps!

Torsten.

Re: Hot to configure 2nd network port

Thanks for spending time on my query,
But can I use both the ports at a time?
my problem is that My old printer(having parallel port) has gone out of repair. & I need to replace it with a USB or a netwrok printer which are available in the market now days.
& hance wanted to connect the network printer on the spare RJ45 port
Thanks

Re: Hot to configure 2nd network port

As said, there are 2 connectors, but it is the same LAN. You can only use one of them at a time.

Hope this helps!

Torsten.

Re: Hot to configure 2nd network port

adding a network printer is not equivalent to connecting it to the 712 machine you have, using a rj45 network cable. If you think, this is the way you will connect a network printer, you need to revise your understanding of these devices before moving any further. If all you are after is connecting a network printer, you do not need to configure a different network interface. You can add your network printer to your existing network thru your AUI connection, somewhere on the same network.

Re: Hot to configure 2nd network port

I'd guess the reason for the original question is that the other network hardware on the site is coaxial-based (10base2, thin Ethernet) and the budget for extra hardware is probably minimal.

As others have said, the 712/80 does not have two integrated NICs: it has just one NIC, which can be switched to use either the AUI port or the RJ-45 port. But it cannot use both ports at the same time.

Back in the last century :) when my previous employer was doing a migration to RJ45-based network, we had bought piles of cheap 8-port 10/100 RJ45 hubs which had one BNC connector we used for uplink. Long before the new cabling was ready, we bought all new network hardware with RJ45 connectors and plugged them in those hubs. When the installation of new switches and cabling was ready, we just moved the network cables from those hubs to the new RJ45 sockets.

If your network is still coax-based, you really should have a plan for transitioning to a modern network technology; new coax hardware is getting hard to find and RJ45 cabling is certainly a proven technology.

I'd expect that transition equipment (like RJ45 hubs with a coax uplink port) will be getting harder to find as time goes on, because the manufacturing volumes are vastly on the RJ45 side by now.

Re: Hot to configure 2nd network port

Thanks all,
Dear Matti Kurkela, it is correct that my existing network is coax based & the printer available now in the market is having RJ45 port only.
As you said can we migrate the network (BNC to RJ45)without any configuration changes in system.
My existing system(workstation) works as a boot server for 2 more diskless x-station, and all 3 are having a spare RJ45 port.
So can I use a n/w switch & connect all 3 with a n/w printer.
Pls guide
Thanks again

Solution

Re: Hot to configure 2nd network port

In short:
- Find a switch that has a coax connector and enough RJ45 connectors to satisfy your near-future requirements.

- Connect the switch to the existing coax segment using an Y cable, just like another workstation.

- Connect your printer into the RJ45 connector on the switch.

(Small unmanaged switches won't have anything to configure, or maybe just a switch to determine whether the coax connector or a RJ45 connector is used as the uplink port. Bigger "managed" switches may need some configuration first; read the documentation of the switch.)

- If your workstation is already running a BOOTP/DHCP server, you can use it to assign an IP address for the printer. Otherwise, read the printer's documentation to configure a static IP address to it.

- Now your printer should be reachable by IP address from any host in your network. You'll also have a switch you can use as a connection point for RJ45-based hosts and other network devices: that should make it easier to expand your network in the future.

If you choose to get multiple 10/100 (or better) switches, you may want to run a RJ45 cable between them and cut the coax network into separate "islands" for each switch. That would allow the switches to use a 100Mbit (or better) data transfer speed between them: you'd effectively get a faster "backbone" for your network.

Re: Hot to configure 2nd network port

Thanks all,
Dear Matti Kurkela,
I have arranged a switch of same type you said, Now I am able to connect the 2 diff types of network, But when I am trying to install a Network Printer(SAM-Add-n/w based printer), It is showing me a message saying "The TCP-IP spooler software is not installed on your system , Therefore it is not possible to add TCP-IP protocol printer"

Pls help which patch/sw shall I have to install & how so that I can Install n/w printer
Thanks

Re: Hot to configure 2nd network port

You would need the HP JetAdmin software for your HP-UX 9.05. Unfortunately both JetAdmin and your HP-UX version are so old, they are no longer downloadable from HP:

http://h20000.www2.hp.com/bizsupport/TechSupport/Document.jsp?objectID=bpj06765

"HP Jetadmin obsolescence
The following HP Jetadmin software was obsolesced on 31 Jan 2002 and is no longer available for download from HP.com
...
* HP Jetadmin for HP-UX 9.x and lower, 10.x, 11.x
..."

The replacement software is called "HP Jetdirect Printer Installer", but it does not exist for HP-UX 9.x. Only for 10.00 and later versions:

http://h20180.www2.hp.com/apps/Lookup?h_query=jet+direct+printer+installer&h_tool=software&h_lang=en

However, there might be a way. If the printer supports LPD print protocol, you might be able to configure it to your old workstation as a "Remote" printer.

You can test this using telnet from the workstation. For example, if the printer's IP address is 11.22.33.44, run:

telnet 11.22.33.44 515
If telnet says "Connection established", the printer supports LPD. (You'll need to press Ctrl-] and then type "close" to disconnect from the printer.)

In that case, you can use SAM to configure a Remote printer: set the "Remote System Name" to the printer's IP address, and "Remote Printer Name" to "raw". Set the name of the printer to whatever you like, and apply the settings.

Re: Hot to configure 2nd network port

Thanks,(Sorry for delay)
I have tested a new printer It is working as a remote printer, with a small problem,
It is printing the HPGL Graphs correctly,
But Some Text Reports (Lex) are not commimng properly, IT is printing only the starting First Line, & left the remaining page blank, Also after each printout it is printing one page, Showing User: ,Host:, Class: & Job:
How can I disable this second extra page?
Thanks.

Re: Hot to configure 2nd network port

First, make a small text file with just a few short lines in your workstation, and print it. If each line in the printout starts where the previous line ends, it's called "stair-stepping". It means the printer expects MS-DOS style end-of-line characters (i.e. a CR+LF combination). Unix systems typically use LF only as an end-of-line character.

Many printers can be configured to accept Unix-style end-of-line characters too. Without knowing your printer model, I cannot give more detailed instructions: please see the documentation of your printer.
(This configuration change will usually not affect printing from Windows workstations at all; Windows printer drivers can automatically override this setting as necessary.)

The extra page is called a "banner page" or "separator page". The HP-UX print spooler can generate a banner page if configured to do so. The JetDirect network adapter in HP network printers can also generate a banner page if configured to do so. Some printers can also generate a banner page in the actual printer mechanism, so you may have up to three places to check.
