Lock options: There are lock options for a slot (see Figure 5-10). These will lock a slot, all of the slots on the bus that a slot is a member of, or the unit (the physical chassis or I/O expansion enclosure that a slot is a member of). Locking slots excludes them from being processed by: Add Card Wizard Performance optimizer, described in 5.1.3, "Analyzing an existing configuration" on page 144. Note: The table view does not provide access to the lock function. The LED on the slot itself will blink as does the graphic of the slot, as shown in Figure 5-11. Figure 5-11 Slot 3 with the LED on 7. To hot add the adapter into the slot, open the cover on the x440 or RXE-100. Push the orange tab above the adapter slot in the direction of the arrow, toward the rear of the x440 or RXE-100, and swing the black adapter retaining arm so that it is vertical. This will allow us to remove the blank filler plate and add the adapter. 8. Once the adapter is installed, return the black adapter retaining arm to the closed position. The orange tab will click back into place, locking the adapter retaining arm down. Important: Be sure to close all adapter retaining tabs before closing the cover on the x440 or RXE-100, or the cover will not close properly and forcing it will likely break the adapter retaining arm. 140 IBM ^ xSeries 440 Planning and Installation Guide
