3. Use the Navigation keys to scroll down to highlight the current baud rate across from the
appropriate Comm Channel.
4. Press the “Enter” (F4) key to select the Comm channel to change.
5. Navigate to underline the desired baud rate—2400.
6. Press the “Enter” (F4) key to lock in the new baud rate.

Status and alarm conditions are available on an optional remote alarm monitor (RAM) panel.
8.2.3 Dust Filter
Installing the two dust filters in the Liebert NX requires only a Phillips screwdriver. Each filter is
held in place by a bracket on either side of each filter. To install each filter:
1. Open the UPS door and locate the filters (on the back side of the front door; see Figure 43).
2. Remove one bracket and loosen the screw on the second bracket. The second bracket need not be
removed (see Figure 43).
3. Remove the dust filter to be replaced.
4. Insert the clean filter.
5. Reinstall the bracket, tightening the screw securely.
6. Tighten the screw on the second bracket.
