We expect the user to configure ha_sync / ha_data port in port_configs already\n\n### SRX cabling\n\nsee [Chassis Cluster User Guide for SRX Series Devices](https://www.juniper.net/documentation/us/en/software/junos/chassis-cluster-security-devices/topics/concept/chassis-cluster-srx-series-node-interface-understanding.html) Here’s the recommended cabling.\n\n#### SRX300\n\nFrom ZTP / default state, ge-0/0/0 and ge-0/0/7 (SFP) are default WAN ports and will get DHCP IP. However, ge-0/0/0 becomes OOB/fxp0 after cluster is enabled (i.e. using it for reach Mist is not recommended)\n\n1. form cluster in UI\n2. configure ge-0/0/7,ge-1/0/7 for WAN (reth0)\n3. configure ge-0/0/2,ge-1/0/2 for ha_data\n4. configure ge-0/0/3- for LAN or additional WAN e.g.\n    \n\n``` json\n{\n    \"port_config\": {\n        \"ge-0/0/2,ge-1/0/2\": {\n            \"usage\": \"ha_data\"\n        },\n        \"ge-0/0/7,ge-1/0/7\": {\n            \"usage\": \"wan\",\n            \"redundant\": true,\n            \"reth_idx\": 0,\n            \"ip_config\": {\"type\": \"dhcp\"}\n        },\n    }\n}\n\n```\n\n1. connect ge-0/0/1 back to back for ha_control\n2. connect ge-0/0/2 back to back for ha_data\n3. connect both ge-0/0/7 to uplink switch to WAN and to reach Mist\n4. power up both devices\n5. it takes about 30 minutes for the cluster to form\n    \n\n#### SRX320\n\nFrom ZTP / default state, ge-0/0/0, ge-0/0/7 (SFP) and cl-1/0/0 (LTE) are default WAN ports and will get DHCP IP. However, ge-0/0/0 becomes OOB/fxp0 after cluster is enabled (i.e. using it for reach Mist is not recommended)\n\n##### ZTP via ge-0/0/7\n\nSimilar to SRX300\n\n##### ZTP via cl-1/0/0 (LTE)\n\n1. form cluster in UI\n2. configure cl-1/0/0, cl-3/0/0 as WAN (reth0)\n3. configure ge-0/0/2,ge-3/0/2 for ha_data\n4. same as above\n    \n\n#### SRX340 / SRX345 / SRX380\n\nSRX340/SRX345 has dedicated OOB/fxp0 ports\n\n1. form cluster in UI\n2. configure ge-0/0/0,ge-5/0/0 for WAN (reth0)\n3. configure ge-0/0/2,ge-5/0/2 for ha_data\n4. configure ge-0/0/3- for LAN or additional WAN\n5. connect ge-0/0/0 to uplink switch to WAN and to reach Mist\n6. connect ge-0/0/1 back-to-back for ha_control\n7. connect ge-0/0/2 back-to-back for ha_data (fabric); or for SRX380, xe-0/0/16 if 10G SFP+ is used\n8. connect ge-0/0/3- to LAN or additional WANs\n    \n\n#### SRX550\n\nge-0/0/0 becomes OOB/fxp0 after cluster is enabled, make enable oob_ip_config as dhcp to maintain cloud connectivity\n\n1. connect ge-0/0/0 to reach Mist (after cluster is fully up, this port becomes OOB/fxp0)\n2. connect ge-0/0/1 back-to-back for ha_control\n3. connect ge-0/0/2 back-to-back for ha_data (fabric)\n4. connect ge-0/0/3 to WAN (after cluster is up, intended to be used for reth0)\n5. connect ge-0/0/4- to LAN or additional WANs\n    \n\n#### SRX1500\n\nSRX1500 has, additionally, dedicated HA Control port\n\n1. form cluster in UI\n2. configure ge-0/0/0,ge-5/0/0 for WAN (reth0)\n3. configure ge-0/0/1,ge-5/0/1 for ha_data\n4. configure ge-0/0/2- for LAN or additional WAN\n5. connect dedicated ha_control back-to-back\n6. connect ge-0/0/0 to uplink switch to WAN and to reach Mist\n7. connect ge-0/0/1 back-to-back for ha_data\n8. connect ge-0/0/2- to LAN or additional WANs\n    \n\n#### SRX4100\n\nSRX4100 has dedicated ha_control and ha_data (fabric) ports\n\n1. connect dedicated ha_control back-to-back\n2. connect dedicated ha_data back-to-back\n3. connect xe-0/0/0 to WAN to reach Mist\n4. connect xe-0/0/1- to LAN or additional WANs\n    \n\n#### VSRX\n\nWhen standalone, VSRX has fxp0 as first Network Adapter, then ge-0/0/0-N When clustered, VSRX has fxp0, em0, then ge-0/0/0-N\n\n1. connect net0 (fxp0) to WAN to reach Mist\n2. connect net1 back-to-back for ha_control\n3.  connect net2 (ge-0/0/0) back-to-back for ha_data (fab0/fab1)\n4. connect net3 (ge-0/0/1) to WAN, intended to be used for reth0\n5. connect net4 (ge-0/0/2) to LAN\n    \n\nSRX340/SRX345 has dedicated OOB/fxp0 ports VSRX has fxp0 as first Network Adapter, then ge-0/0/0-N\n\n1. connect ge-0/0/0 to WAN to reach Mist\n2. connect ge-0/0/1 back-to-back for ha_control\n3. connect ge-0/0/2 back-to-back for ha_data (fabric); or for SRX380, xe-0/0/16 if 10G SFP+ is used\n4. connect ge-0/0/3- to LAN or additional WANs\n    \n\n#### SRX550\n\nge-0/0/0 becomes OOB/fxp0 after cluster is enabled, make enable oob_ip_config as dhcp to maintain cloud connectivity\n\n1.  connect ge-0/0/0 to reach Mist (after cluster is fully up, this port becomes OOB/fxp0)\n2. connect ge-0/0/1 back-to-back for ha_control\n3. connect ge-0/0/2 back-to-back for ha_data (fabric)\n4. connect ge-0/0/3 to WAN (after cluster is up, intended to be used for reth0)\n5. connect ge-0/0/4- to LAN or additional WANs\n    \n\n#### SRX1500\n\nSRX1500 has, additionally, dedicated HA Control port\n\n1. form cluster in UI\n2. configure ge-0/0/0,ge-7/0/0 for WAN (reth0)\n3. configure ge-0/0/1,ge-7/0/1 for ha_data\n4. configure ge-0/0/2- for LAN or additional WAN\n5. connect dedicated ha_control back-to-back\n6. connect ge-0/0/0 to uplink switch to WAN and to reach Mist\n7. connect ge-0/0/1 back-to-back for ha_data\n8. connect ge-0/0/2- to LAN or additional WANs\n\n    \n#### SRX1600\n\nSRX1600 has, additionally, two dedicated HA Control port\n\n1. form cluster in UI\n2. configure ge-0/0/0,ge-7/0/0 for WAN (reth0)\n3. configure ge-0/0/1,ge-7/0/1 for ha_data\n4. configure ge-0/0/2- for LAN or additional WAN\n5. connect dedicated both ha_control back-to-back\n6. connect ge-0/0/0 to uplink switch to WAN and to reach Mist\n7. connect ge-0/0/1 back-to-back for ha_data\n8. connect ge-0/0/2- to LAN or additional WANs\n\n\n#### SRX4100\n\nSRX4100 has dedicated ha_control and ha_data (fabric) ports\n\n1. connect dedicated ha_control back-to-back\n2. connect dedicated ha_data back-to-back\n3. connect xe-0/0/0 to WAN to reach Mist\n4. connect xe-0/0/1- to LAN or additional WANs\n\n\n## Replace a Node in a HA Cluster\nUsually Device Replacement is done by Device Replacement API.
