Powering Server On and Off
007-4653-001 33
Powering Off at System Console
To power off your server at the system console, follow these steps:
1. At your console, switch to L2 mode by pressing
Ctrl+T.
2. From the L2 prompt (L2>), power off an individual brick by typing the following
command. (If you want to power off the entire server, proceed to the next step.)
L2> r <rack#> s <slot#> pwr d
For example, to power off a Cx-brick in rack 1, slot 07, type the following:
L2> r 1 s 7 pwr d
The slot number is the lowest unit number that the brick occupies within a rack (see
Figure 1-14 on page 21).
If you want to power off several bricks from a rack at the same time, you must type
the rack number followed by the slot numbers of the bricks you want to power off.
For example, to power off bricks in slots 7 and 11 of rack 4, type the following:
L2> r 4 s 7,11 pwr d
If you want to power off bricks that reside in the same location in multiple racks,
you must type the number of the racks followed by the slot number of the bricks
you want to power off for each rack. For example, to power off the bricks in slot 11
of racks 3 and 4, type the following:
L2> r 3, 4 s 11 pwr d
Caution: To avoid problems with your server, do not try to power off multiple slots
for multiple racks at the same time.
3. If you want to power off all the bricks in all the racks, type the following command:
L2> pwr d
(The default setting for the
pwr d
command is all racks and all slots.)
4. From the L2 prompt, display the brick configuration information by typing the
following command:
L2> config
This command lists all the bricks in the server and each brick’s system controller
address.
