TMC Low Sub-system FQDN’s:

Below are the FQDN’s of the TMC Low components. For updated FQDN’s kindly refer values.yaml in the TMC Low charts.

TMC Low component

FQDN

Central Node

ska_low/tm_central/central_node

Subarray Node

ska_low/tm_subarray_node/{id}

CSP Subarray Leaf Node

ska_low/tm_leaf_node/csp_subarray{id}

SDP Subarray Leaf Node

ska_low/tm_leaf_node/sdp_subarray{id}

NOTE{id} is the identifier for the deployed subarray.

For instance, if two subarrays are deployed

Subarray 1 will be:

Subarray Node : ska_low/tm_subarray_node/01

CSP Subarray Leaf Node: ska_low/tm_leaf_node/csp_subarray01

SDP Subarray Leaf Node: ska_low/tm_leaf_node/sdp_subarray01

MCCS Subarray Leaf Node: ska_low/tm_leaf_node/mccs_subarray01

For Subarray 2:

Subarray Node : ska_low/tm_subarray_node/02

CSP Subarray Leaf Node: ska_low/tm_leaf_node/csp_subarray02

SDP Subarray Leaf Node: ska_low/tm_leaf_node/sdp_subarray02
