TCX1000-RDM20 Front Panel and FRU Panel


The front panel of the TCX1000-RDM20 contains a serial port, USB port, Ethernet ports, SFP port, status LEDS, 20 universal ports, LINE ports, monitor ports, and system status LEDs. The FRU panel of the TCX1000-RDM20 contains the fan modules and power supplies and the grounding point.

STATUS LEDs display the status of the TCX1000-RDM20.
OSC 1 IN/OUT OSC connection ports for 1611 nm wavelength. 3
RESET Reset switch.1
OSC IN/OUT SFP cage; host port for the pluggable OSC transponder. 4
OSC 0 IN/OUT OSC connection ports for 1511 nm wavelength.
DCN 0 and DCN 1 are the Ethernet management ports.
MON IN/OUT Monitor port.
ETH CRAFT/USB ETH CRAFT is the craft port; the USB is not used.
LINE IN/OUT The LINE port connects to the fiber plant or an inline amplifier (TCX1000-ILA). Line input port and line output port.
SERIAL Serial port for serial management access.
U0 to U19 20 universal ports. 2

1 Reset switch–A recessed pinhole-style switch is located on the front faceplate. The switch is a momentary contact device, which you can hold down to trigger either a warm or cold restart of the TCX1000-RDM20, depending on the duration it is held. See Table 1.

Table 1: Reset Button

Reset Duration


250 to 8000 ms

Warm reset of the TCX1000-RDM20. It does not impact the data plane but management connectivity is lost to the network element for the duration of the restart.

Longer than 10 seconds

Cold reset of the TCX1000-RDM20. It shuts down all traffic passing through the device. This forces a restart even in the event system software has become unresponsive. This also resets all active optical modules within the device.

2 Universal ports–All optical connections used on the TCX1000-RDM20 are LC type connectors, arranged in duplex pairs. The connectors are organized in two rows across the faceplate, with the bottom row being inverted to allow easier finger access to the fiber removal latches. The IN/OUT connector pairs are designed to work with duplex fiber cables. Ports U0 I to U19 I are the mux input ports, and ports U0 O to U19 O are the demux output ports.

3 OSC ports–These ports are used to connect to the OSC SFP port. You can connect the OSC SFP to the OSC 0 port to have full OSC optical power monitoring on the 1511-nm wavelength. The OSC 1 port is designed to support a 1611-nm channel but it is unused at this time. The OSC 0 IN is the add port for the OSC Tx and the OSC 0 OUT is the drop port for the OSC Rx.

4 The SFP cage–This port provides OSC-band signal transmit and receive functionality for a two-fiber, bidirectional optical link. The OSC signal provides Ethernet network connectivity between the TCX1000-RDM20 nodes. The TCX1000-RDM20 includes optical filters to support an OSC channel at either a 1511-nm or 1611-nm wavelength. The SFP port uses the standard pin out as per the SFP MSA and accepts MSA-compliant transceivers. The transceivers must be capable of supporting 100Base-FX. For more information, see the list of supported SFP tranceivers in the TCX Series Optical Transport System Feature Guide.

The cooling system in TCX1000-RDM20 consists of two fan modules. The fan modules can be hot-swapped—you do not need to power off the TCX1000-RDM20 or disrupt the TCX1000-RDM20 function to replace a fan module.

The TCX1000-RDM20 has two 650-W power supplies, either AC or DC depending on your configuration. Only one power supply is required to power the device, while the second power supply provides redundancy. When the TCX1000-RDM20 has both power supplies installed and is connected to power, the device has full power redundancy. If a power supply fails or is removed, the other power supply balances the electrical load without interruption. Each power supply provides 12 VDC output with a standby voltage of 12 VDC. The power supplies can be hot-swapped—you do not need to power off the TCX1000-RDM20 or disrupt the TCX1000-RDM20 function to replace a power supply.
