Installing a RAD or DR in an existing HAL System
There may be times when you need to install a new RAD or DR after a HAL System is already up and running.
Because the RADs and DRs are hot-swappable, in other words, you can replace a RAD or DR without having to
power down the system, the process is fairly simple. If you are installing a RAD or DR in an existing HAL Sys-
tem, you are likely doing one of three things:
l
Installing a new RAD or DR
l
Replacing a RAD or DR that is not working
l
Replacing a RAD or DR with a different model
In all three situations, the HAL behavior is the same. It automatically detects the new RAD or DR and compares
its model number to the model number configured in the HAL or EXP for that port. If the model numbers match,
the HAL sends the relevant configuration data as well as any required firmware updates to the RAD or DR. If the
model numbers do not match, the HAL or EXP front panel LEDs flash yellow (for RADs—the Enabled LEDs flash
yellow, for DRs—its only LED flashes yellow). The mismatch is also indicated on the devices themselves. On the
RAD, the Power, Comm, Audio Rx, and Audio Tx LEDs flash red. On the DR, a flashing exclamation mark
appears along with the words
Configuration Mismatch .
Installing an additional RAD or DR into an existing system:
1. Follow the same procedure that was outlined in the previous section. You do not need to power
down the HAL or EXP before or after installing the RAD or DR.
2. Update the HAL configuration to reflect the additional RAD or DR. If you were given a new con-
figuration file that includes the additional RAD or DR, you need to load it into the HAL. See "Task
2: Configuring HAL" on page 74 for details. If you do not have a configuration file, you need to
update the configuration on the live device. Remember to save the new configuration to a file.
Replacing an existing RAD or DR with the same RAD or DR model:
1. Remove the old RAD/DR by detaching the Decora plate, unscrewing the RAD/DR from the switch-
box, and unplugging the shielded CAT 5e cable.
2. Connect the shielded CAT 5e cable to the replacement RAD or DR.
