Feature Description - Alcatel-Lucent 7210 SAS M Configuration Manual

System Management
optically terminates all the channels using either the 4-channel or the 8-channel termination
module. The second channel is the intermediate OADM sites with 7210 SAS-M, and 7210 SAS-
X. These sites use the CWDM passive units to add or drop channel in both the directions (east and
west), for traffic to be processed by the node. Additionally these sites provide express lanes for all
the other channels (that is, those not processed locally by the node). The 1830 VWM provide an
option for add or drop up to 1, 2, 4 channels of fixed wavelength to be processed locally by the
node.

Feature Description

The 1830 VWM clip-on device can be connected to a master-shelf, that is, the 7210 SAS node
using the USB interface or the OMC interface, depending on which interface is supported by the
7210 SAS platform. Each of these clip-on devices is identified using the shelf ID set using the
rotary dial provided on the device. To assist inventory management, the user must configure the
vwm-shelf-id of the clip-on device attached to the 7210 SAS node using the CLI command
configure>system> vwm-shelf <id> > vwm-type <type> create. The vwm-shelf-id must match
the shelf ID set using the rotary dial on the clip-on device. 7210 SAS devices, uses the configured
vwm-shelf-id to communicate with the clip-on device. If these shelf IDs do not match, 7210 SAS
cannot communicate to the device and does not provide any information about the device. 7210
SAS cannot detect a mismatch between the configured vwm-shelf-id and the shelf ID set on the
rotary dial. Depending on the type of interface, USB or OMC, only a fixed number of 1830
devices can be managed by the 7210 node. The software fails any attempt to configure more 1830
devices than what can be supported by the interface in use. The users can use the show command
provided by the 7210 SAS devices to display the shelf inventory information and alarm status
information provided by the clip-on device. In addition to inventory management, 7210 SAS
supports provisioning of cards inserted into the slots available on the 1830 devices. The user must
provision the card and card-type (also known as, module type) before the card can be managed by
the 7210 SAS. The 7210 SAS detects and reports mismatch in provisioning of the card. It also
detects and reports insertion and removal of the card/module from the slot on the 1830 device.
The 1830 DWDM supports active and passive units. The first 1830 DWDM device that is
connected to a 7210 node using the OMC port or the USB port must be equipped with active
DWDM controllers, while passive DWDM controllers can be used in the other chassis connected
to the first device in a stacked configuration. In other words, the first 1830 DWDM device that is
connected to the OMC port or the USB port of the 7210 node cannot be a passive 1830 DWDM
device, while subsequent chassis in the stacked configuration can be equipped with passive
DWDM controllers. The decision to equip active or passive DWDM controllers on the other
chassis in the stacked configuration can be found by using the "1830 VWM User Guide".
NOTE: The 7210 SAS also auto detects the device type when any of the supported devices are
connected to the USB interface. Only approved USB mass storage device and optical clip-on
devices can be plugged in to the USB port and are recognized as valid devices. All other
