Replacing an Accel Hub
1. Turn off the power to the Accel Hub.
2. Disconnect all cables and the AC power cord.
3. Replace the Hub with a new one.
4. Connect the AC power cord and all cables – remembering to clean and correctly
connect the uplink and downlink cables.
5. Connect the null modem cable to the PC and then to the Hub’s front panel DB-9
serial connector.
6. Start the AdminManager software.
7. Select the Installation Wizard option from the AdminManager main window.
8. Turn on the power to the Hub.
9. Observe the LEDs after turning on the power.
If there is no band programmed in the Hub, the LEDs will blink
continuously and there is no communication with connected
Expansion Hubs or their RAUs.
If there is a band programmed, the LEDs blink for a 5-second
test. The programmed band is then issued to all Expansion Hubs
and their RAUs, and a system test is performed. It can take up to
1.5 minutes to complete the test. During System Test, the entire
system is temporarily off-line and no RF is being transmitted.

During System Test, the entire system is temporarily off-line and no RF is
