Physical Considerations

Rack Mounting

R/2 includes a pair of rack rails designed to secure the unit to the rear of the equipment rack. It is highly recommended that you install these rails if possible due to the depth of the unit. Mounting by the front panel alone may cause excessive strain on the chassis and is not recommended. The supplied rails should fit in most standard equipment racks, but if installing the rails is not possible, you may wish to consider placing an upside-down rack shelf underneath the unit for additional physical support.

Airflow

As with most rack-mount server ch assis, the airflow on R/2 is from front to back. While it is not absolutely necessary to leave an additional rack space above and below the unit, it certainly is not a bad idea if the space is available. Do not block the front panel of R/2 behind a solid rack door.

Wiring Management

Since airflow is from front to back, it is important to keep the rear of the unit free from obstructions to allow for hot air exhaust. Install the wiring in such a way that it allows for a reasonable service loop and does not block airflow. Do not allow wiring from other equipment in the rack to block airflow from the rear panel of R/2.

Rear Panel

Power

The R/2 is equipped with dual power supplies (120V – 240V, 50 – 60Hz) to allow for facilities with redundant power feeds to the equipment racks from separate sources. An LED on the supply will indicate the presence of AC power and proper operation. If power is lost on one of the AC inputs or one of the supplies should fail, the R/2 will sound an alarm. The only way to mute this alarm is to connect power to both supplies or (in the case of power supply failure) remove the failed supply.

Note: If only one of the two power supplies is connected, an alarm will sound. Connect both supplies to AC power, even if you don’t have redundant AC power feeds to the equipment rack.

RS-232

Not currently implemented. Inserting stream metadata via RS-232 will be supported in a future release. See chapter 10 (Metadata Sources and Filters) for more details about stream metadata.

“Control” Ethernet Port

This port (if populated) is intended for out-of-band system management. Not currently implemented.

USB Ports

Future expansion or factory service. Not currently implemented.

NIC 1 and NIC 2

The R/2 offers dual network adapters. Typically, one adapter (NIC1) would be used for Audio over IP, while the second (NIC2) would be dedicated to streaming audio traffic. Either interface can be used for management via the web GUI. Connect your network(s) to NIC 1 and/or NIC 2. Do not connect both interfaces to the same network. Doing so may cause routing and connectivity issues.

Note: Do not connect both interfaces to the same network simultaneously. Routing and connectivity issues may result. Ensure each interface is connected to a different IP network, (different VLAN, physical switch, IP address block, etc.) as necessary. Consult your IT department or Telos technical support if you are not sure how the interfaces should be configured. Only one interface may be needed in some rare cases.

VGA

Factory service only. Not currently implemented.

Audio (AES/EBU)

Eight AES/EBU audio connections are available through two high-density 26-pin D-sub connectors. Connect the provided breakout cable(s) to the D-sub connectors. Use the thumbscrews to securely attach the cables in place. Sample rate conversion is provided on all inputs. The BNC Word Clock connectors are not currently implemented. Each audio channel can be configured to generate a stream at 44.1 or 48 kHz (see Chapter 7: Audio Source Configuration).

Power Up

Press the “On/Off” button located on the right half of the front panel to power up the unit (See Chapter 4 for a full front panel description). During the power up process, the front panel will light up and display a splash screen. If the display remains dark and fans do not spin up, verify that AC power is present at both power supply inputs.

If the fans spin up but the display remains dark or does not show a splash screen, contact support.

Fans

The fans in R/2 are thermostatically controlled. As the unit powers up, the fans will start at full speed. They should spin down to a much slower speed after a short period of time. If they do not return to low speed, it may indicate a faulty fan or other hardware issue. During normal operation, these fans may increase in speed if the unit’s internal temperature rises. If the fans remain at full speed during operation and the environmental temperature of the unit appears normal, contact support.

Note: The fans will run at full speed for a brief period of time during boot. They should return to a relatively moderate speed within a short period of time. If the fans remain at full speed, it may indicate a hardware fault. Slightly higher fan speed during operation is normal if the internal temperature of the unit increases.

Input Level Meters

Once the unit has fully booted, the front panel LCD will display the input audio level meter screen. As of software version 1.0.34, these meters can display either AES or Livewire input levels by using the up and down navigation arrows on the front panel.

Livewire and other Audio over IP input sources (as well as output level metering and processing metering) can also be metered via the unit’s web GUI or via NfRemote for Omnia.9 processing (See Chapter 16 for Omnia.9 processing information).

Note: Select between Livewire or AES input levels by using the up and down navigation arrows from this screen (see chapter 7 for information about defining audio sources). Metering can also be accessed from within the web GUI or NfRemote software (if using Omnia.9 processing).
