Powering On the Sun Fire E6900 System
Note – It is advisable to connect an administration console to the system during
installation. Refer to the Sun Fire Midrange Systems Platform Administration Manual for
terminal settings and connections.
1. Begin with a safety inspection of the system.
a. Turn the AC power switches off on the redundant transfer unit (RTU) modules
at the front and rear of the system (FIGURE 2-11).
b. Verify that the system AC power cables are connected to a wall socket and the
power supplies.
Caution – Do not disconnect the AC power cable from the wall connection when
you work on or in the Sun Fire E6900 system. This connection provides a ground
path that prevents damage from electrostatic discharge (ESD).
2. Power on the wall circuit breakers.
3. Power on any expansion cabinets.
Read the documentation supplied with each type of expansion cabinet for specific
instructions.
4. Power on the RTS power switches (FIGURE 2-11).
