We are running SRX5800 in a cluster. Each Node has FPCs as well as SPCs installed. Due to some maintenance downtime , we were required to power off FPCs as well as SPCs on a backup node , not in a whole cluster.

Considering the fact that Node 1 (SRX5-2) is the active firewall for both redundancy groups and Node 0 (SRX5-1) is the backup firewall , we used the command `'request chassis fpc slot 0 node 0 offline' on active firewall. This command ran well and FPC went offline. The FPC model is SRX5k DPC 4X 10GE.

When we used the same command i.e. 'request chassis fpc slot 7 node 0 offline' to power off the SPC , however it didn't went offline. Having said that , SPC is installed in slot 7 position of Node 0 and the SPC model is SRX5k SPC.

user@SRX5-2> request chassis fpc slot 7 node 0 offline 
    Offline command not supported for FPC in slot 7


user@SRX5-2> show chassis cluster status 
Cluster ID: 1 
Node                  Priority          Status    Preempt  Manual failover

Redundancy group: 0 , Failover count: 1
    node0                   200         primary        no       no  
    node1                   100         secondary      no       no  

Redundancy group: 1 , Failover count: 3
    node0                   255         primary        no       yes 
    node1                   100         secondary      no       yes

Based on the above output , is it possible to turn off the SPC card in a SRX5800 series firewall or SPC card can't be turned off.

Thanks !!

  • Can you add "show chassis cluster status" please? Nov 13, 2021 at 14:53
  • @JordanHead. Sure I have added the output in the the question body.

That would appear to be the case. Juniper's documentation only shows a full chassis shutdown when messing with an SPC. (shutdown and power off the standby unit.)
