Pass WAN Packets
•
SP_IAM
: This controls whether the Gateway passes wide area I_AM packets from the serial
port to the RollCall Network. Normally this is enabled to allow PCs attached to the serial
port to be located by other units, but it may be disabled if you wish to control the flow of
I_AM packets through a system.
•
SP_TIME:
This controls whether the Gateway passes wide area TIME packets from the
serial port to the RollCall Network. Normally this is enabled to allow PCs attached to the
serial port to be time servers, but it may be disabled if you wish to control the flow of TIME
packets through a system.
Port Mode
This item shows the current operating mode of the serial port (RS-422, RS-232 or RS-485).
Report if PSUs Missing
When these boxes are checked it will allow a missing PSU report to be displayed in the
Unit
Status
area and logged.
If two power supply units are fitted, in the dual redundancy supply configuration, the
Left PSU
and
Right PSU
items should be selected.
If for some reason one of the power supplies is removed, a warning will be displayed,
indicating which power supply is missing.
If only one power supply is fitted, only the corresponding check box should be selected and
the other cleared.
Enclosure Type
The 3U enclosure can be equipped for high power or quiet operation. The
Enclosure Type
radio buttons select which hardware type is fitted to the enclosure.
•
IQH3B (High Power Enclosure)
: Select if the standard PSUs and fans are fitted in the
IQH3B enclosure. Maximum power usage is 165 LU.
•
IQH3BQ (Quiet Enclosure)
: Select if the quiet PSUs and fans are fitted in the IQH3BQ
enclosure. Maximum power usage is 100 LU.
Note:
Pass I_AM (Bridge) overrides both Pass I_AM (Serial) and Pass I_AM
(IP). So if Pass I_AM (Bridge) is set I AM messages will be passed over the
bridge, irrespective of how the other controls are set.
Note:
The Gateway will always use the received time stamp, whether it
passes it on or not.
Note:
If a PSU is fitted but fails or is turned off then a warning message
will always be generated.
Note:
Do not select if the IQH3B enclosure is fitted with quiet PSUs and
fans. This can lead to overheating.
