Frequently Asked Questions (FAQ)

Q: Do I really need to use the included rails for mounting R/2 in the rack?

A: Not necessarily, but it does keep strain off the front panel and makes it easier to mount in the rack. If you don’t want to use the rails, you might still want to consider placing an inverted rack shelf underneath R/2 for support.

Q: I’m not getting any response from R/2 at all…No LEDs, no fans, no front panel display. What’s wrong?

A: Check that you’ve connected AC power to both power supplies. A green LED should illuminate on each supply to indicate presence of AC power. Try different power cords (stranger things have happened) and check that the AC power outlet(s) are actually live. Press the front panel “On/Off” button. If R/2 still doesn’t power up, contact technical support.

Q: I’ve connected power, but the unit won’t stop beeping. How do I stop the beeping?

A: You probably did not connect AC power to both supplies. There are a number of good reasons to do this, particularly if your facility is designed with redundant AC power feeds to each rack, though you should attach power to both supplies even if this is not the case. If the unit still beeps after you have connected power to both supplies and double-checked that the the power source(s) feeding both supplies are actually good (and that the power cords are OK) you may have a power supply fault. Remove the faulty or disconnected supply and the beeping should stop.

Q: I powered up the R/2 and noticed a lot of fan noise. Is this normal? Can I mount R/2 in the studio?

A: The fans on R/2 are temperature controlled and individually monitored for speed. They are designed to spin up to full speed at power up, but should slow down to a more moderate speed during boot. A slight increase in fan speed during operation could indicate elevated internal temperatures (possibly due to lack of airflow) but if the fans remain at full speed after boot or during otherwise normal operation, it may indicate a fan or other hardware failure. While the R/2 can operate relatively quietly, it would likely be audible in a studio environment with live mics. We recommend mounting R/2 in the rack room or other control room away from live mics if possible. It isn’t necessary to access the front panel after initial setup. All monitoring and configuration can be performed remotely via the web GUI once the unit has been powered up and assigned an IP address.

Q: Why can’t I access R/2 via the network?

A: Check that you have set the IP address, subnet mask, and gateway correctly via the front panel, or that a valid IP configuration has been acquired via DHCP (Chapter 5). Verify that you are connected to the correct network interface port (Chapter 3: NIC 1 on the left, NIC 2 on the right). Ensure that the link and activity LEDs on the corresponding port illuminate, and that the corresponding (Net 1/Net 2) LED on the front panel flashes with network activity (Chapter 4). Note that R/2 will NOT respond to a “ping” request, though you should be able to access the internal web GUI from a browser (Chapter 6). Verify that you are able to use the same port on the network switch with another system.

Q: I’ve got R/2 up and running, now what?

A: Once you’re able to access the web GUI, the default login is “user” with no password. First, add an audio source (Chapter 7). Second, add a processing or encoding instance (Chapter 8). Finally, adjust the processing as desired (Chapter 9 for Omnia 3, Chapter 16 for Omnia.9).

Q: Why don’t I see anything in the list of “Discovered Channels” under the “Livewire Driver” settings?

A: Verify that at least one of the R/2 network interfaces is configured and connected to your Livewire network, and that the proper interface is selected in the “Livewire Driver” settings (Chapter 7). If you still aren’t seeing any channels in the list, try restarting the Z/IPStream R/2 Encoder serivce (Chapter 14).

Q: I’ve configured several audio sources from Livewire or RTP, but why don’t I see any audio levels on the front panel?

A: By default, the front panel will display the AES audio input levels. Livewire audio sources can be displayed by using the up/down arrow keys from the metering screen. All other processing and audio level metering can be performed via the web GUI (Chapters 6 through 9) or via NfRemote for Omnia.9 processing (Chapter 16).

Q: Why aren’t the local AES/EBU audio card inputs appearing in the list of available WAVE devices?

A: This may indicate an issue with the audio card. Shut down R/2 and remove power from both AC power inlets for 30-60 seconds. Power R/2 back up. If the AES inputs are still not available to add as WAVE (Local Audio Card) sources, contact technical support.

Q: How can I add Omnia.9 processing or additional audio sources to my R/2?

A: Contact sales or your favorite Telos/Omnia dealer to license additional sources (see Chapter 12 for license management). Up to 8 audio sources are supported on R/2, each with included Omnia 3 processing or optional Omnia.9 processing. These sources can be each used in multiple processing and encoding instances simultaneously (see Chapers 7, 8, 9 and 16).
