The Ribbon Edge 8300 device features interfaces for analog telephony access:
- On the front panel, each of the 4 x T1/E1 ISDN PRI interfaces can be enabled or disabled by configuration.
- On the back panel, each of the 24 FXS/FXO interfaces can be enabled or disabled by configuration.
The FXS/FXO interfaces on the back panel are available in two configurations: either 24 FXS ports, or 22 FXS ports and 2 FXO ports. The ports are not interchangeable: FXS ports cannot be configured as FXO ports or vice-versa. An Amphenol connector (also known as a telco connector) on the back panel provides access to the FXS interfaces. Two RJ-11 ports provide access to the FXO interfaces.
For power, the Ribbon Edge 8300 device offers three types of power supplies: single power supply and redundant AC or DC power supply.

Fans
The fans help the device stay cool. To avoid the device overheating, place the device in an area that allows free airflow in front of the fan vents.
Power Switch
The power switch is used to switch on or off the device or to reset the device. The power and status LEDs on the front panel turn solid green after the device powers on.
The power switch operates in two modes, depending on the device configuration:
| Power Supply Type | Power Switch Operation |
|---|---|
| Single AC power supply | Power On-Off: Press the switch to turn on or turn off the hardware |
| Redundant AC or DC power supply | Power Reset: Press the switch for 4 - 5 seconds to perform a hardware reset |
Redundant AC Power Supply
The redundant AC power supplies are hot swappable and can be removed and replaced without shutting down the device, provided that one of the power supplies is online and working.
An audio alarm sounds if a power supply fails or is missing. Press the black button on the right side of the PSU cage to silence the alarm.
Redundant AC Power Supply - LED Status
| Power Supply Condition | Power Supply LED |
|---|---|
| Output ON and OK | Green |
| No AC power to all PSU | OFF |
| AC present/only standby output on | 1Hz Flashing Green |
AC cord unplugged or AC power lost; with a second power supply in parallel still with AC input power. | 1Hz Flashing Red |
Power supply warning events where the power supply continues to operate; high temp, high power, high current, slow fan. | 1Hz Flashing Red/Green |
Power supply critical event causing a shutdown; failure, OCP, OVP, UVP | Red |
Redundant DC Power Supply
The redundant DC power supplies are hot swappable and can be removed and replaced without shutting down the device, provided that one of the power supplies is online and working.
An audio alarm sounds if a power supply fails or is missing. Press the black button on the right side of the PSU cage to silence the alarm.
Redundant DC Power Supply - LED Status
| Power Supply Condition | Power Supply LED |
|---|---|
| Output ON and OK | Blue |
| No DC power to all PSU | OFF |
| DC present/only standby output on | 1Hz Flashing Blue |
DC cord unplugged or DC power lost; with a second power supply in parallel still with DC input power. | 1Hz Flashing Red |
Power supply warning events where the power supply continues to operate; high temp, high power, high current, slow fan. | 1Hz Flashing Red/ Blue |
Power supply critical event causing a shutdown; failure, OCP, OVP, UVP | Red |
Analog Ports
The 8300 supports two analog port configurations on the back of the chassis:
- 8300-24S: 24 FXS ports
- 8300-22S-2X: 22 FXS ports and 2 FXO ports
When present, the FXO interfaces appear as a pair of RJ-11 ports.
The FXS ports connect using a 50-pin Amphenol connector (also known as a telco connector), which can be wired to a breakout panel. Order the optional breakout panel and cable from Ribbon using the following codes:
