6 Multi-UPS Systems

6.1 Caution

Please check complete list of UPSs compatible with our Redundancy/Parallel mode service:

Caution:

We strongly recommend you contact trained technical support for setup, in order to guarantee the integrity of

your high-availability system.

Recommendations:

• For the UPS Models it is better to Enable "Communication Shutoff orders" so that the UPS accepts

Network Management Card off commands.

Exception for 2 UPSs in Hot standby (Sequential redundancy)

• The Network Management Cards MUST have the same shutdown criteria parameters.

You can use default settings (or duplicate configuration using specific tools like Mupgrade)

• For 3 phase UPS systems it is mandatory to check battery parameters before installing Network

Shutdown Module.

6.2 Presentation

With the latest version the Network Shutdown Module manages multi UPS redundant configurations.

The Network Shutdown Module V3 makes it possible

• to supervise an installation made up of several UPSs. It provides the user with an overall view of the

installation by concentrating the information acquired from the individual UPSs. The data acquisition is

performed through the IP network.

• to trigger the shutdown of the machine on which it is installed, taking into account the consolidated

« global » view of the electrical installation.

The Network Shutdown Module V3 manages following electrical configurations:

• Several UPSs in parallel:

Note only for MGE Galaxy 7000:

When UPS is in ‘’Power Saving mode (PSM) in progress’’, it is

considered by NSM as redundant UPS.

• 2 UPSs in Hot standby (Sequential redundancy):

Note: For the UPS Model that is close to the load you have to

disable "Communication Shutoff orders" so that the UPS

transfers to bypass and doesn't accept Network Management

Card off commands.

(You can use the UPS display or the UPS Configuration tool)

• 2 UPSs in serial redundancy:

1 2 ... 22 23 24 25 26 27 28 29 30 31 32 ... 52 53
