IP Crossover Cable
You can connect the any PC with a 10Base-T or 100Base-T RJ45 Ethernet port to the
Gateway using an RJ45 crossover cable. This looks like a standard RJ45 patch cable, but is
wired differently. Connect the crossover cable to the RJ45 ports on the PC and on the rear of
the 3U enclosure. Configure the PC to use the following IP parameters:
IP address: 192.168.151.2
Subnet mask: 255.255.0.0
Default IP Gateway: blank
In the Commtrol window on the PC, go to File | Configure Comms. Select IP Server and set
the IP address to 192.168.151.1. You should now be able to connect to the Gateway.
Detailed Configuration Steps
1.
On PC change the TCP/IP LAN Properties to 192.168.151.2 (.1 is the IP address of
the gateway) Take note of default TCP/IP to restore afterwards.
2.
Set control panel connection “Build network” to 192.168.151.1.
3.
Open the RollCall control panel and template for gateway, go to Ethernet page.
4.
Set all Ethernet parameters (address. subnet/gateway), then hit “Take IP Address
Changes”.
5.
Reconfigure the PC’s TCP/IP LAN configuration to its original properties.
6.
Connection to the gateway's IP may be tested only if PC and gateway have valid rout-
ing to allow this. If so, reset the “Build Network” in control panel to point to the gate-
way's new IP address.
3.15.3 Simple Network Management Protocol (SNMP)
The Gateway can run an SNMP agent which allows direct control of both its own controls and
those of modules within the chassis. Unlike a RollCall IP connection, an SNMP connection is
for this 3U box only. If you wish to control other 3U boxes then each must be connected via
Ethernet and controlled by SNMP individually.
SNMP also provides logging information. Log messages, similar to those sent to a RollCall
logserver, can be sent to up to 8 separate destinations (SNMP trap destinations).
By default, the SNMP agent is disabled. A set of MIB modules have been created that map
controls for each card type and provide other mappings. These are required in the SNMP
manager operation.
At a minimum, to control the gateway, you need the following MIBs:
SNELL-WILCOX-SMI.MIB
SNELL-WILCOX-TC.MIB
SNELL-WILCOX-PRODUCT-REG.MIB (Id for each card type)
SNELL-WILCOX-UNIT.MIB
SNELL-WILCOX-GATEWAY-LOGGING.MIB (card and gateway logging tables)
SNELL-IQH3A-CMD-MIB.MIB (gateway controls)
SNELL-WILCOX-MODULAR-GATEWAY.MIB (required if legacy SNMP support is
enabled).
This is a hierarchical MIB structure and must be compiled in order if your SNMP manager
does not support conditional compilation.
