Software power-off—This powers off node or switching fabric slots on a slot-by-
slot basis through the distributed management card. Note that you will only be
able to power off node or switching fabric slots using this method; the distributed
management cards will remain powered on. This enables you to power-on the
node or switching fabric slots remotely through the distributed management
cards using the software power-on instructions.
2.2.1 Performing a Hardware Power-Off
1. In preparation for bringing down the operating system and powering off the
server, ensure that all significant application activity is quiesced on the server.
2. Locate the power switch at the rear of the Netra CT 820 server and press it to the
Off (O) position (
FIGURE 2-1
).
Caution –
The power switch turns off the output of the power supplies. To
completely disconnect power to the system, you must remove the input feed power
going to the DC terminals at the rear of the server.
3. If you want to completely power off the Netra CT 820 server, remove the service
panel cover from the DC terminal block and disconnect the DC supply terminals
from the terminal block (
FIGURE 2-1
).
Note that you must disconnect the DC supply terminals from both the A terminals
and the B terminals on the terminal block in order to completely remove power from
the Netra CT 820 server.
2.2.2 Performing a Software Power-Off
1. Log into your Netra CT 820 server through the distributed management card or its
rear transition module, and administer the system.
See Appendix B for instructions on connecting a terminal to your server, if necessary.
