Install the ATA 191
Procedure
Step 1
Connect the power supply to the Cisco DC Adapter port.
Step 2
Connect a straight-through Ethernet cable from the network to the network port on the ATA. Each ATA ships
with one Ethernet cable in the box.
Attach a Phone to the ATA 191
Before You Begin
You can attach one or two phones to an ATA 191.
Procedure
Connect one or more phones to a phone port of the ATA with an RJ11 cable.
The PHONE1 and PHONE2 LEDs on the ATA light as solid green when there is activity on that port.
Startup Process Verification
After your ATA has power connected to it, it begins the startup process by cycling through these steps:
1 The Power LED flashes during the startup process.
2 The Problem Report Tool (PRT) LED lights solid amber during initial bootup. The LED then flashes
amber and then green while the application and kernel are booting.
If the PRT LED lights red during bootup, then either the MIC certificate failed, or the ATA failed to obtain
a network address.
3 The LED for Phone 1 flashes while the Phone1 port boots, followed by the LED for Phone 2.
After the Phone1 and Phone2 ports register with Cisco Unified CM successfully, the corresponding LEDs
are lit with solid green. If a phone port fails to register, the LED rapidly flashes in green three times, then
repeats.
4 When the ATA has successfully booted, the Power LED lights solid green and the PRT LED turns off.
The Network LED flashes as traffic is detected.
When you go offhook on the phone, the phone LED begins to flash, and you hear the dial tone. The ATA has
completed the startup process.
