There are two types of ring locations. One is a channel termination location, with the
1830 PSS-32 that optically terminates all the channels using either the 4-channel or
the 8-channel termination module. The second location is the intermediate OADM
sites with 7210 SAS-M. These sites use the CWDM passive units to add or drop a
channel in both directions (east and west), for the node to process traffic.
Additionally, these sites provide express lanes for all other channels (that is, those
not processed locally by the node). The 1830 VWM provides an option to add or drop
up to 1, 2, 4 channels of fixed wavelength for local processing by the node.

6.6.2 Feature Description

The 1830 VWM clip-on device can be connected to the 7210 SAS node (the master
shelf) using the USB interface or the OMC interface, depending on the interface
supported by the 7210 SAS platform. Each of these clip-on devices is identified using
the shelf ID, which is set on the rotary dial provided on the device.
To assist inventory management, the operator must use the
configure>system>vwm-shelf vwm-shelf-id vwm-type vwm-type create CLI
command to configure the vwm-shelf-id of the clip-on device attached to the
7210 SAS node. The vwm-shelf-id must match the shelf ID that is set on the rotary
dial of the clip-on device. 7210 SAS devices use the configured vwm-shelf-id to
communicate with the clip-on device. If the shelf IDs do not match, the 7210 SAS
cannot communicate with the device and does not provide any information about the
device. The 7210 SAS cannot detect a mismatch between the configured vwm-shelf-
id and the shelf ID set on the rotary dial.
