7210 SAS-MXP, R6, R12, S, SX, T BASIC SYSTEM
CONFIGURATION GUIDE RELEASE 22.9.R1
System management
– 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.
6.6.3 1830 VWM configuration guidelines and restrictions
The 7210 SAS manages the 1830 VWM CWDM/DWDM clip-on device, and inventory, and displays
information about the clip-on device including part numbers, clip-on type, manufacturing dates, firmware
revision, and status of alarms. The 7210 SAS also supports provisioning of modules that can be inserted
into the available slots on the 1830 device. The following are the configuration guidelines and restrictions
that apply to the 1830 VWM:
• The shelf-ID on the rotary dial must be set to a numeric value between 1 to 7. Digits higher than 7 are
not supported by 7210 SAS devices.
• The 1830 VWM clip-on device is connected to a master-shelf (for example, a 7210 SAS device).
Each clip-on device is identified using the shelf ID set on the rotary dial provided on the device. To
aid inventory management, the user must configure the vwm-shelf-id of the clip-on device attached
to the USB interface or the OMC interface. The vwm-shelf-id must match the shelf ID that is set using
the rotary dial on the clip-on device. The 7210 SAS uses the configured vwm-shelf-id to communicate
with the clip-on device. If the two shelf IDs do not match, the 7210 SAS cannot interact with other
devices and is unable to provide 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.
• The 7210 SAS provides a show command to display the alarm status information communicated by the
clip-on device.
• 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, see 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.
