Microtronix Access X.25–TCP/IP Gateway
3 Quick Start Guide
C nfigurati n f the Access Gateway will require a PC r lapt p with standard Internet br wser like
Internet Expl rer r M zilla Firef x. Opti nally, a serial COM p rt ( r USB serial adapter) n the PC
with a terminal emulat r applicati n may be used t c nnect t the C ns le p rt.
3.1 Installation
1) The Access Gateway may be placed n a shelf in a rack, r m unted using a rack m unt kit.
2) C nnect t the IP netw rk thr ugh the RJ45 10/100 Netw rk p rt. T c nnect directly t the PC,
use the Ethernet cr ss cable (red).
3) Opti nal: C nnect the C ns le p rt t the PC using the C ns le Cable. Refer t the “C ns le
P rt” secti n bel w f r instructi ns.
4) C nnect AC/DC p wer adapter and AC p wer c rd ( r attach the -48VDC p wer c rd)
5) Wait 30 sec nds f r the b t pr cess t c mplete. The RUN led will start t blink.
3.2 Ethernet / IP Port
The Ethernet p rt can be used f r initial c nfigurati n. The default IP address f the Access Gateway is
10.1.1.240/24. T c nnect via IP, set the PC's IP address t 10.1.1.200, and subnet mask t
255.255.255.0 (10.1.1.0/24).
3.2.1 Web Interface (htttp / https)
The Access Gateway has a web-based server f r c nfiguring and m nit ring. Use any Internet
br wser t c nnect t the web interface. L gin is required with username “admin”, and default
passw rd “admin”.
3.2.2 Terminal Interface (telnet / ssh)
The Access Gateway will als accept Telnet r ssh client c nnecti ns f r advanced m nit ring and
tr ublesh ting. The username is “r t”, and the default passw rd is “f0adA” (0=zer ) f r privileged
access, and “admin”, “admin” f r n n-privileged access.
3.3 Console Port (Optional)
The C ns le p rt ffers system c ntr l access during the b t-up pr cess. B t messages will be
displayed if a PC COM p rt is c nnected using the C ns le Cable, and a terminal emulat r like “putty”
r “HyperTerminal” is set f r 9600-N-8-1.
3.3.1 U-Boot Command Access
After p wer up, there is a 10 sec nd delay that all ws U-B t c mmand access:
Autoboot in 10 seconds (Enter password to stop)...
if the passw rd “f ad” is typed while the message is displayed, the U-B t pr mpt “A4K:>” will indicate
c mmand readiness.
3.3.2 Setting Default IP Parameters
The default IP netw rk parameters may be m dified r added here as an alternative t the c nfigurati n
via the web interface. Enter the f ll wing c mmands t change the default IP address, netmask,
default gateway (if needed), and pti nally a new system “h stname”
set ipaddr 10.1.1.240
set netmask 255.255.255.0
set gatewayip 10.1.1.1
www.micr tr nix.c m 7

Microtronix Access X.25–TCP/IP Gateway
set hostname MYNAME
save
boot
These defaults will remain in effect until again changed again in U-B t, r explicitly changed via the
Ethernet c nfigurati n page in the web interface.
3.3.3 Emergency IP Address Recovery
The u-b t c ns le may be used t rec ver a f rg tten IP address. While in the U-B t c ns le, the
default IP address and ther parameters may be displayed:
print ipaddr
print netmask
print gatewayip
If the default values are n t in current effect, they may verride the system-defined values temp rarily
by setting new default values (if desired) and entering the U-B t c mmands:
set runlevel 2
save
boot
When the system starts up, it will be using the default IP address inf rmati n, and sh uld be reachable
n that netw rk. Br wse int the web interface and access the Ethernet page t view the “f rg tten”
values. Restart the system t get the U-B t c ns le, and reset run level:
set runlevel
save
boot
The system will restart with the system-defined values.
3.3.4 System Firmware Updates
The u-b t c ns le may als be used in c njuncti n with Micr tr nix supp rt f r applying firmware
updates, and emergency IP address rec very.
T apply firmware updates:
1) Obtain the kernel image (uImage) and/ r filesystem image (jffs2.img) files fr m Micr tr nix
2) Start a tftpd server n the PC r an available file server
3) Place the file(s) in the tftpd default direct ry n the PC r server
4) Enter the PC r server IP address (example 10.1.1.200) using the u-b t c mmands:
set serverip 10.1.1.200
save
5) L ad the new kernel image:
run updatekernel
6) L ad the new filesystem image:
run updatejffs2
7) Start the system by re-applying p wer r typing the “b t” c mmand.

Microtronix Access X.25–TCP/IP Gateway
3.4 Configuration Web Interface
The default IP address f the Access Gateway is 10.1.1.240. The PC used t access the web interface
must be c nfigured (temp rarily) f r an address in the same subnet, f r example, 10.1.1.200. C nnect
the PC t the same LAN, r temp rarily use the red Ethernet cr ss ver cable t c nnect directly t the
Access Gateway.
Open the web br wser n the PC, and enter http://10.1.1.240 in the URL field. When
pr mpted by a p pup wind w, l gin using default user name: admin, and passw rd: admin.
The h me page will be displayed with the main menu d wn the left hand side.
The Access Gateway can n w be c nfigured by selecting the main menu items. Each page
has a Help butt n in the upper right c rner f r viewing additi nal inf rmati n specific t the
current page.
Note: If using Wind ws Internet Expl rer, C mpatibility View may need t be enabled. This can be
d ne by clicking n the “br ken page” ic n in the address field f the address bar, r by adding the IP
address using the C mpatibility View Settings IE T ls menu.

3.5 IP Network Configuration
T create r m dify the IP netw rk parameters different than the default values defined in U-B t ,
btain the new IP address, netw rk mask, and default gateway values. F ll w this pr cedure nly if
y u d n't want the default values t be used in the running system.
Fr m the main menu System secti n, select Ethernet t display the c nfigurati n f rm.
1) M dify the H stname as desired.
2) Enter the new Default Gateway IP address, if needed.
3) Click n the Select butt n in the Ethernet Interfaces table c rresp nding t “eth0”.
4) Enter the new IP address and netw rk mask.
5) Click the Apply butt n f r the changes t be saved and t take affect.
C nnect the Netw rk p rt t the new netw rk, if n t already. Since the IP c nnecti n may be l st due
t the change, the new address may need t be entered in the br wser. The Ethernet c nfigurati n
page displays the current status f the Ethernet interface.
F r m re inf rmati n n additi nal netw rk c nfigurati n, click the Help butt n n the page.
