Description: Tracks power, cooling, slot occupancy, and shelf inventory for Cyan optical chassis hardware.

Start monitoring vendor-neutral, standards-based MIB, any SNMPv3-capable network device (SNMP engine identity/boot/clock status) with a free 30-day trial of IPNetwork Monitor. Import MIBs, browse SNMP OIDs, create custom SNMP monitors, configure alerts, and monitor any SNMP-enabled network device from a single console.

What Is CYAN-SHELF-MIB?

CYAN-SHELF-MIB is a vendor-specific MIB from Cyan (an optical networking/packet-optical transport vendor) that monitors chassis shelf inventory, power, cooling, and slot occupancy for Cyan optical transport hardware. It provides an inventory-style table describing each shelf's identity, asset tag, MAC address, and bay location alongside environmental/health indicators. This MIB is squarely a hardware-status monitoring module: it directly exposes fan speed and fan-filter replacement interval for cooling health, days-since-last-replacement for maintenance/lifecycle tracking, and an autoprovisioning flag reflecting the shelf's operational/software provisioning state, all of which are core signals for detecting overheating risk, aging hardware, or a shelf that failed to auto-provision correctly. It sits alongside other Cyan enterprise MIBs covering card- and port-level detail within the same optical chassis, of which the shelf MIB provides the top-level container view. It is typically deployed in optical transport/packet-optical network elements at telco central offices or carrier points of presence. Engineers can download the CYAN-SHELF-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in CYAN-SHELF-MIB. Use the built-in SNMP Monitoring Browser to explore available variables, view their current values and descriptions, and select the objects you want to monitor. You can then create SNMP monitors, configure thresholds, and receive alerts when monitored values change.

Supported Devices

Cyan packet-optical transport chassis
Cyan optical network element shelf

Monitoring Examples

An operator would poll cyanShelfTable and its cyanShelfFanSpeed column across all cyanShelfEntry rows to detect a cooling fan slowing down or stopping, a leading indicator of thermal risk to the cards installed in that shelf. cyanShelfFanFilterReplacingIntervalDays combined with cyanShelfDaysSinceLastReplacement would be used to schedule preventive filter maintenance before airflow degrades. cyanShelfAutoprovisioningFlag would be checked after inserting a new shelf to confirm it came up and auto-provisioned correctly, and cyanShelfAssetTag/cyanShelfBaseMacAddress used for inventory reconciliation against asset-management records.

What Can Be Monitored

fan speed
fan filter replacement interval/age
shelf autoprovisioning status
shelf/bay identification and asset tag
base MAC address
days since last hardware replacement

How to Use in IPNetwork Monitor

Example using cyanShelfFanSpeed OID:

Select a Cyan packet-optical transport chassis (shelf inventory/environmental) as the target host to create a monitor — the SNMP service should be up and running on it. Click New Monitor, then check SNMP Custom on the Favorites tab, click Next, and confirm the host. On the next page, click Select... to open the built-in SNMP MIB Browser and type cyanShelfFanSpeed into the Find box to locate it in the OID tree, selecting the specific row/instance you want to monitor since this is a table column, then select it and click OK. It reports the fan speed. On the monitor's Main parameters page you can set the target's SNMP port (default 161), credentials, polling interval, and other settings — see the SNMP Monitor help for details. On the State conditions and Alerting tabs, configure when the monitor should change state and trigger an alert; since this is an Integer32-type OID, Value bounds is the most useful condition here — trigger an alert if the speed drops below the level expected for a healthy, spinning fan, since a stalled or slowing fan often precedes overheating. Click Finish to create the monitor; you can adjust any parameter later.
