24UPS Network Management Card 2 User’s Guide

The End of Shutdown options enable you to set a condition and a delay time for when a UPS can turn back on

after AC utility power is restored. You can specify a Minimum Battery Capacity before the UPS will turn

back on. Set another pause, if necessary, before turning on with Return Delay.

Shutdown delays and forcing negotiations. A shutdown time for the UPS is calculated differently for a

UPS device with NO outlet groups compared to a UPS with outlet groups.

1. For a UPS with NO outlet groups, the shutdown time is the Maximum Required Delay value on the

NMC Shutdown screen plus 2 minutes plus the shutdown delay for the UPS.

2. For a UPS WITH outlet groups, the shutdown time is the Power Off Delay value on the NMC Outlet

Groups screen, see “Outlet Groups on Configuration menu”. (Not available with all UPS devices).

Note that devices with the prefix SUM behave like #1 above, not #2.

For both types of UPS, the shutdown time is negotiated by the NMC interacting with PowerChute Network

Shutdown (PCNS).

Use the Force Negotiation option (Configuration - Shutdown) to re-gauge the time when you change or add

a PCNS client. When you force a negotiation, the procedure is automatic; the details are discussed below.

PCNS starts with the NMC Low Battery Duration value, compares it to its own shutdown time and, if the

battery duration time is too low, tells the NMC to increase the values in #1 and #2 below to the

PCNS

SHUTDOWN REQUIRED TIME* plus 70 sec.
