After modeling a Juniper SRX580 device in Spectrum using the JuniperJUNOSrtr model type, the model does not appear under the Chassis Manager.
Release : 10.4.x
Component : Spectrum Discovery/Modeling
For Juniper devices to appear under the Chassis Manager in OneClick, they must support the jnxBoxAnatomy mib.
Reference the "Identification of Chassis Devices" section of the documentation.
When a device supports a DX NetOps Spectrum certified proprietary chassis MIB, it is identified as a chassis device. For example, when a "Juniper" device supports the "jnxBoxAnatomy", it is identified as a chassis device based on that MIB.
Using MIB Tools, verify if the device supports/populates the jnxBoxAnatomy mib.
Check if the device in question is part of a cluster with 2 nodes. If the node in question is the standby node, not all mibs are available for standby nodes, which, in this case, is the jnxBoxAnatomy mib.
