• The 7210 SAS only recognizes approved USB mass storage and optical clip-on
devices need as valid devices when plugged in the USB port. All other devices
are treated as unsupported and cause the 7210 SAS to generate an error log. A
shelf created by the user is operationally down when an unrecognized device is
plugged into the USB port.
• OMC ports must be used for 1830 DWDM device management on 7210 SAS-T
and 7210 SAS-Mxp. USB ports are not supported on these platforms.
• Management of the 1830 DWDM device is not supported on the 7210 SAS-R6
and 7210 SAS-R12.
• Only a single 1830 CWDM or DWDM device can be managed using the USB
interface.
• The management capabilities available through USB and OMC port are similar.
• The first 1830 DWDM device that is connected to the OMC port or the USB port
of the 7210 SAS node must be equipped with active DWDM controllers; it must
not be a passive 1830 DWDM device. However, subsequent chassis connected
to the first 1830 DWDM device in a stacked configuration are allowed to be
equipped with passive DWDM controllers. For more information about stacking
configuration, refer to the 1830 VWM product manuals.
• The number of DWDM or CWDM devices that are supported in a stacked
configuration managed by the 7210 SAS is limited. Please contact your Nokia
representative for information about the number of units supported.
• In a stacked or cascaded configuration, all 1830 VWM units connected to the
7210 SAS must be of a similar type, either ec-cw or ec-dw/ec-dwa. A mix of
CWDM and DWDM types is not supported.
6.6.3.1 1830 VWM LED Functionality
Table 39 and Table 40 describe the LED functionality of the device.
Note: The 1830 VWM allows for a mix of passive DWDM and active DWDM devices in a
stacked configuration; the configuration is supported on all 7210 SAS platforms.
