Smart-UPS Battery Protocol

Smart-UPS XL models are not designed to know how many external battery packs are connected to them. You must program the Smart-UPS XL with the appropriate number of external batteries in one of four ways.

Note:

It is important to follow these instructions. The number of batteries affects the run time calculations which

Smart-UPS performs when it is running on battery power.

Use the Smart-UPS Battery Pack Utility (BATTPACK)

This program can be used with DOS or at a Microsoft® Windows DOS prompt.

BATTPACK cannot be used with a DOS emulator or VDM (virtual DOS machine) like those in Windows 95, Windows 98, or Windows NT.

The APC UPS Link cable must be used to communicate to the UPS. There are two black cables which can be used; part numbers 940-0024C or 940-1524C.

Note:

For the purposes of this formula, 1 rack mount battery pack (SU48RMXLBP) = 2 stand-alone battery packs.

At the DOS prompt, type: battpack com[X] [Y] where:

[X]represents the available serial port that Battery Pack Utility uses to access the Smart-UPS.

[Y]represents the number of external battery packs.

For example: C:> battpack com1 4

The black cable is attached to communication port 1. There are four external battery packs. The program confirms that the update is successful.

Use PowerChute® plus Version 5.x for Windows 95, Windows 98, Windows NT

PowerChute plus 5.x for Windows NT is compatible with NT 3.5.1 SP5, NT 4.0 Workstation (at least SP1), or NT 4.0 Server (at least SP1).

After rebooting the computer, access the PowerChute plus graphical user interface.

1.Click on Configuration.

2.Click on UPS Operating Parameters.

4.Click OK.

Use the Terminal Program to Change the Number of External Battery Packs

1.EXIT out of the PowerChute plus Server. In the case of Windows NT, the UPS Service must be stopped.

2.Go to: Program Manager > Accessories > Terminal. Double-click on the Terminal icon.

3.Select the COM port to which the black-colored interface cable is attached as the Connector.

4.The COM port settings are 2400 baud, 8 data bits, 1 stop bit, no parity, flow control is Xon/Xoff.

5.Click OK.

6.Continue with the table in Step 7 in Use the HyperTerminal Program to Change the Number of External Battery Packs, page 22.
