Q-NET™ PDQS Redundancy Switch Installation and Operating Handbook

2022-04-26
This installation and operating handbook covers the Q-NET™ PDQS redundancy switch. The backup modem, which may be a Q-Flex™ or Q-MultiFlex™ modem, also acts as the Switch controller and is physically separate from the redundancy switch.
Figure 1-1 shows the redundancy switch, consisting of a 3U, 19-inch chassis.
Figure 1-2 shows the backup modem fitted underneath. The backup modem reports the status of the Switch and is used to control the Switch.
A rear view of the Switch is shown in Figure 1-3. The rear houses up to four modules each of which supports up to four traffic modems. The Switch has an ‘umbilical cable’ (situated in the centre, bottom) that links it to the backup modem.
Figure 1-4 shows how the umbilical cable connects between the Switch and backup modem.
As well as front-panel control, the Switch can be controlled from a web browser or through SNMP (all via the backup modem).
