The following figure shows the 1830 DWDM shelf and the entities that can be managed by 7210 SAS.
The following information applies to the management of the 1830 DWDM shown in the preceding figure:
Slot 1 and Slot 2 host the DWDM Power and Controller modules (either EC-DW or EC-DWA). These slots host the Equipment Controller; power is provided by the Service NE (using EC-DW unit) or the TRU (using EC-DWA unit) in accordance with the system configuration and the Equipment Controller used. A rotary switch located on the top side of the Equipment Controller is used to set the SHELF_ID. In a stacked configuration, each Shelf_ID must be uniquely set. The Shelf_ID must be identical for the active and standby controllers in a shelf.
Slot 1 and Slot 2 are not directly provisioned by the user in the 7210 SAS. The user must provision and configure the vwm-type managed by the 7210 SAS. The vwm-type can be provisioned as ec-cw, ec-dw, or ec-dwa, indicating that the shelf is a CWDM passive shelf or a DWDM passive shelf or a DWDM active shelf.
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 the 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 can be equipped with passive DWDM controllers.
Slot 3 and Slot 4 are capable of hosting DWDM filters (MUX/Demux), optical amplifiers, and Bulk Power Management (BPM) module. These slots must be explicitly provisioned on the 7210 SAS to allow management by the 7210 SAS. The 7210 SAS can manage the following cards:
all DWDM filter (remote and manual filter and all of 2-channel, 4-channel and 8-channel)
fan module
BPM module (which allows for the aggregation of 44 DWDM channels using SFD44 unit) is not supported
The 7210 SAS host tracks the following events related to the modules in Slot 3 and Slot 4:
line card/module removal and insertion
provisioning mismatch, if the provisioned line card does not match the equipped line card
LoS alarm reported by the card/module for remote filter. The LoS alarm is cleared by the ec-dw/ec-dwa based on the threshold configured VOA.
monitoring power levels for remote filter is not supported and configuration of power thresholds for automatic power monitoring feature supported by the remote filter units is not allowed
1830 DWDM fan module insertion and removal
Slot 5 hosts the fans or the Inventory Extension Module (IN/MOD). If the 7210 SAS is managing the 1830 device, provisioning Slot 5 is not supported. As a result, only the fan module can be equipped in the slot; IN/MOD is not supported.
