1027145–0001 Revision D 6–36 Installing indoor hub equipment Hub installation
To prepare to commission the HT (chapter 7), you:
• Perform a CCM power–on test (this section)
• Check the status of each main component (section 6.10)
The objective is to verify that the equipment is operational before
commissioning. If you find a problem, you can correct it prior to
commissioning so it will not delay the commissioning process.
Before you conduct the power–on test, make sure all AIReach
Broadband equipment is properly connected.
1. Check these connections, with power to the IDU off:
• IDU to ODU (IFL from IDU to lightning arrestor
and from lightning arrestor to ODU)
• ODU ground connections
• IDU ground connections (if required)
Observe the CCM startup diagnostics (SUDS):
2. With all equipment installed and connected, apply power to
the IDU and observe the front panel LCD.
(For the tests and status checks described in this chapter, the
HT does not have to be connected to the EMS.)
When you power up the IDU, the CCM initializes and
performs SUDS. During SUDS, the LCD on the CCM front
panel shows the following messages, in the sequence
shown.
Equipment function is normal when you see the
messages shown below and no failure messages.
