GANDALF 5250I LAN BRIDGE
The purpose of this Information Release is to provide product and configuration information for the Gandalf LANline 52501.
The LANline 5250I is a high performance, multi-port router with bridging capabilities and optional ISDN.
As a bridge it uses MAC tables to decide which traffic to forward. As a router it routes IP and IPX traffic.
It also supports :
*Point to Point Protocol, (PPP), over ISDN, Leased lines, Dial up lines or switched digital facilities.
*Frame Relay Protocol with PPP or PVCs.
A standard 5250I is shipped with :
*One aui LAN interface (DB15)
*Two WAN ports supporting upto 64kbps. These ports are switch selectable to support RS232/V24, V.35 or V.11 protocols. (DB15, DB25 or MRAC34)
Options available are :
*10Base2 or 10BaseT interfaces installed using plug-in daughter boards.
*ISDN BRI supporting two 64kbps B channels. (RJ45)
Power :
*115 VAC, 240 VAC, 50/80 Hz, 20 watts maximum.
Dimensions :
*(LxWxH), 26.7 x 20 x 6.6.cm
Environment :
*Operating Temperature - 32 to 104 degrees F
*Humidity - 10 to 60 degrees non-condensing
*Max operational altitude 17000ft
Indicators :
*Run - Illuminates to show that the Bridge is functional.
*LAN - Illuminates that the local LAN is functional
*Link 1, Link 2 - Illuminates to show connection to the WAN(s)
*ISDN - Illuminates to show connection to ISDN
*Bch (x2) - Illuminates to show activity on the ISDN channels. The right led relates to link 3 whilst the left led relates to link 4. If ISDN is not installed then these leds are omitted.
Installing the 5250I :
Position the 5250I in a suitable place. It can either be wall mounted or placed on a table or shelf. It is important that it is positioned adjacent to ISDN BRIs or other Comms equipment as applicable. Customer Services Supervisors are to resolve this as part of pre-installation site surveys.
Ensure that power is disconnected and that full ESD
procedures are implemented.
Undo and remove the two screws on either side of the top of the 5250I. Remove the top cover to expose internals.
If an ISDN daughter board is installed then undo the two retaining screws and carefully remove it.
Ensure that it is placed on an ESD protected surface.
There are two DIP switches, S1 and S2.

Link 2S1All open1-5 closed2-12 closed
6-12 open1 open
Ensure that Link 2 is set for RS232. Set Link 1 as appropriate.
Refit the ISDN daughter board as applicable and refit the top cover.
Connect a terminal to the Link 2 connector. The terminal should be set for 19200 bps, 8 bits no parity and no flow control.
The 5250I is a DCE. This means that the following cable as a minimum is required :
Terminal52501
Pin 1------screen--------n/c
Pin 1--------------------Pin 3
Pin 3--------------------Pin 2
Pin 7--------------------Pin 7
Press Enter
The 5250I should send Date and Time and Login.
To access the configuration software enter 'system'
The 5250I will prompt 'password'
The default password is carriage return. Press (cr).
The micro console command line will appear. To exit at anytime enter 'quit' (cr).
Before configuring individual links it is necessary to setup system wide parameters.
To setup the current date and time, enter :
time,m,HH:MM:SS (cr)
where HH = hour, MM = minutes and SS = seconds
date,m,DDMMYY (cr)
where DD = day MM = month and YY = year
To check the current date and time enter either date (cr)
or time (cr).
The 5250I is very versatile. Configuration scripts will be issued as the 5250I is installed into new environments. There is currently only one tested configuration.
Configuration 1. A single permanent TCP link with ISDN backup.
The ISDN link will be initiated when either there is insufficient bandwidth available on the primary link or if the primary link fails.
Once the correct date and time have been set, input the following on both 5250Is :

Once the configuration is properly entered, then enter quit to exit the micro console configuration utility.
Turn the power off and connect the 5250I to the local LAN, to the comms equipment being used to interface the 5250I into the WAN, (link 1), and the ISDN connector.
Turn the power back on and check the relevant Leds are lit.
To test the Bridge :
Ping the local Bridge from a local device. If this is successful then ping the remote bridge. If this is successful then ping a remote device.
To test the ISDN Circuit :
Disable the primary link by removing the link1 cable.
Ping the remote Bridge.
If this is successful then ping a remote device.
If one Bridge fails to respond re-enter the configuration and retest. If the problem persists then refer to Support for assistance.
If both Bridges fail then refer to Support.
