OSCM
This subsection will help you resolve issues that might be experienced with OSC modules. The following
variants are available:
OSCM-PN, OSCM-V#1630, 2OSCM-V#1630.
Troubleshooting an OSC module is only necessary in case of management or communication problems between
the nodes.
The OSCM-V#1630 has nine LEDs, while the 2OSCM-V#1630 and OSCM-PN each has ten LEDs on the
faceplate:
• “P” to indicate the power supply status
• “Mod” to indicate the operation status of the module
• “N”, (“NE” and “NW” at the 2OSCM-V#1630 and OSCM-PN) to indicate the operating status of the network
port (“NE” - network port east, “NW” - network port west)
• Two LAN LEDs per Ethernet port to indicate the interface status
This section assumes that all measurements for the N, NE, NW interfaces are within ADVA Optical Networking
specifications. If not, refer to “Finding Your Problem - Follow the Light” on p.53 in this document.
Table 70 on p.404 provides troubleshooting guidelines for the OSCM based upon the LED states.
Note
Before you start with troubleshooting, ensure that the current firmware package is installed on
the OSC module. For details on updating module firmware, refer to “Updating the NE Software
Release” on p.617 and “Performing Other Software Update Actions” on p.628.
Note
Before you start with troubleshooting, ensure that the administrative state of the affected module
is configured to “Maintenance”.
