Question on NMC Config and reboot

[Anonymous user]

Hello,

I have a number of  SMT2200RM2U UPS's in my switch closets that contain Network Management Cards (unsure of model #).  I have been tasked with configuring them and getting them on our network.

I have found information on how to connect via the serial port and configure my IP/Subnet Mask/Gateway through the CLI.  In the documentation it shows that it requires a reboot after the configuration.  The switches in my closet are not dual power supply.  Their single power supply is running to the UPS and the UPS is plugged into a power outlet.  

My question is: If I issue the reboot command via the serial connection after I configure the networking does it just reboot the NMC, or does it reboot the UPS and cause an interruption  in power delivery to the switches?  I am trying to see if I can do this during business hours with no service interruption, or if I need to come in after hours.  Thanks

Jeremy

Hi Jeremy,

Anytime you reboot a Network Management Card using the reboot command through CLI (or web), it only reboots the Network Management Card interface itself and not the UPS or other device the NMC may be in (Rack PDU, cooling unit, etc). You could proceed during business hours.

The only exceptions are in other types of devices, like the Rack PDUs (power strips) and when you have other problems/alarms on the system and you reboot the management interface. If there is an internal lost communication between the NMC and PDU intelligence, for example, the NMC may not reboot or be able to re-energize the outlet relays. This is the case because of how the NMC is integrated into that specific product but is not an issue or concern with the products you have. I just mention it in case anyone else comes across this post.

Hope that helps.
