NATIONAL SYNCHROTRON LIGHT SOURCE II

Reported by:	Wilkins, Stuart
Assigned to:	Wilkins, Stuart
Priority	High

Last updated	28/Dec/21 10:36 AM
Expected Resolution	30/Dec/21 10:30 AM

Description

Tomorrow (Wednesday) at 12:01 pm we will make a change to the accelerator firewall to further restrict connections between the beamlines and accelerator to only allowed connections.

There should be no impact on beamline systems, but it is always possible there are legacy systems or processes that we are unaware of that may become blocked.

If you notice any issues after this change, please contact Wilkins, Stuart. We will be able to debug the issue and if the connection is necessary place the required rules into the firewall.

Areas Affected

NSLS-II Beamlines.
