L2> r 1 s 7 pwr u 

The slot number is the lowest unit number that the brick occupies within a rack. For example, in Figure 1-14, the lowest Cx-brick is identified as U07. The next lowest Cx-brick is identified as U11, and so on.

Figure 1-14. Slot or Unit Number

If you want to power on several selected bricks from a rack at the same time, you must enter the rack number followed by the slot numbers of the bricks you want to power on. For example, to power on bricks in slots 7 and 11 of rack 4, enter the following command:

L2> r 4 s 7,11 pwr u

If you want to power on the bricks that reside in the same slot in multiple racks, you must enter the number of the racks followed by the slot number of the bricks you want to power on. For example, to power on the bricks in slot 11 of racks 3 and 4, enter the following command:

L2> r 3, 4 s 11 pwr u

---

Note: To avoid problems with your server, do not try to power on multiple slots for multiple racks at the same time.

---

If you want to power on the entire server, enter the following command:

L2> pwr u

(The default setting for the pwr u command is all racks and all slots.)

From the L2 prompt, display the system configuration by entering the following command:
