Step 5 - Radio Configuration
There are three main QB configuration parameters to review for hot standby operation:
• HSC Mode: Configure the QB to operate within a hot standby arrangement by enabling HSC mode. To access HSC
mode, go to: Setup -> Basestation -> General and enable the HSC Mode. Once HSC Mode is enabled, a range of hot
standby configuration parameters becomes available.
• Unique IP Address: Each QB radio within a hot standby arrangement requires its own unique IP address. To configure
the IP address, go to: Setup -> Network -> Ethernet -> IP Address . For this example, the following unique IP address
allocations have been given:
- Base A IP: 192.168.2.21
- Base B IP: 192.168.2.22
• Shared IP Address: The two QB radios within a hot standby arrangement can be configure to ‘share’ an IP address.
This is an IP address separate from the radio’s unique IP address. The ‘online’ base within the hot standby arrangement
assumes ownership of the shared IP address. The shared IP address has to be configured in Base A & B.
To configure the shared IP address, enable HSC mode, then go to: Setup -> Basestation -> General and enable Shared IP Mode.
For this example, the following shared IP address has been allocated:
- Base A & B Shared IP: 192.168.2.20
When these parameters have been configured, activate the configuration.
Once the configuration is activated Base A will attempt to negotiate and pair with an alternate QB. As Base B is still in a
factory default state, HSC mode negotiation messages will be ignored (until HSC mode is enabled). This will cause Base A to
indicate a pairing alarm, which can be ignored until Base B has been configured.

When Base A has been successfully configured, perform the following steps:
- Force Base B online using the radio select switch on the QHHSC
- Begin from Step 4 and configure Base B
