Monitoring the Cisco 2x2 Remote-PHY Solution

Verifying the Cisco RPD Using the LEDs

Verify the following LEDs located inside the Cisco GS7000 node to check if the RPD is operational.

Table 1. SYS LED Status States

LED Pattern or Color

Status

Description

Green – 2 Hz

Power-On initializing

Indicates good power.

Green – 4 Hz

IP acquired by DHCP, synchronizing and acquiring configuration.

Indicates that remote SSHv2 session is possible.

Green – Steady

System status good – Connection is good.

No faults are detected.

Red – 2 Hz

Connection Fault – No physical connection to CIN or RF Interfaces.

Red – 4 Hz

Configuration fault - Failed synchronization or failed to receive configuration from the CCAP core.

Wrong DHCP configuration, unreachable hosts, failed authentication.

Red – Steady

System Fault – Device cannot initialize.

Hardware fault.

Amber – various

Warning – RPD operational but imperfect.

Vendor defined LED behavior.

Table 2. ETH0 & ETH1 LED’s Status States

LED Pattern or Color

Status

Description

Green – Flash

Per IEEE 802.3x.

Indicates connection state

Unilluminated

Ethernet port failure or port disabled.

Indicates possible port failure or port which has been configured to be disabled.

Table 3. DRF0 & DRF1 LED’s Status States

LED Pattern or Color

Status

Description

Green – 2 Hz

Power-On downstream RF initializing.

At least one pilot and/or tone active.

Green – 4 Hz

Port or ports activated.

Awaiting downstream port set configuration.

Green – Steady

Downstream port set configuration obtained.

Downstream ports operational.

Unilluminated

RF port fault or muted.

Table 4. URF0 & URF1 LED’s Status States

LED Pattern or Color

Status

Description

Green – 2 Hz

At least one upstream port configuration received (and a MAP was received for that port), awaiting upstream burst transmissions.

Indicates that the RPD has received and applied at least one upstream port configuration.

Green – 4 Hz

First upstream transmission recognized.

Indicates that at least one CD’s burst transmission has been received.

Green – Steady

At least one CM has successfully completed upstream ranging.

Upstream deemed operational.

Unilluminated

Upstream RF port fault or no configuration.

Verifying the Cisco RPD Using the CLI

To verify the Cisco RPD status and configuration, use the show cable rpd command. For more information, see the Cisco CMTS Cable Command Reference guide.
