Basic hardware procedures
4.9 Switching on the server
V CAUTION!
● Before switching on the server, make sure the top / side cover is
closed. In order to comply with applicable EMC regulations
(regulations on electromagnetic compatibility) and satisfy cooling
requirements, the PRIMERGY TX140 S1 server must not run while
the top / side cover is removed.
● Follow the safety instructions in chapter "Important information" on
page 41.
Ê Connect all peripheral cables to the rear connector panel of the server.
Ê Connect and secure the power cords as described in section "Connecting
the server to the mains" on page 90.
Ê Connect all power cords to the power outlets.

be connected to a different AC power source from the other supply. If
one AC power source should fail, the server will still continue to run.
