Power-Up Sequence
Observing the power-up sequence may help identify defective hardware or
software issues. Any deviation from the following power-up sequence may
indicate the need for additional technical resources. Please see “Technical
A
ssistance” on page ii for contact information.
1.
Cycle power to the unit and observe the right and left Status
Indicator LEDs and the Ethernet Status LED. (See Figure 36 for
LED location
s.)
2. When power is first applied, the right Status Indicator LED turns
RED. This is the default hardware state and simply indicates that
power is applied.
3. After approximately 8 seconds, the right Status Indicator LED turns
off and the left Status Indicator LED changes from off to yellow.
This indicates the Ethernet processor has booted and is now in the
process of booting the motor control processor.
4. After approximately 4 more seconds, the right Status Indicator LED
changes from off to RED again, indicating that the motor control
processor has completed the boot process.
5. The left Status Indicator LED changes states depending on
conditions described in the section Motor Control on p
age 71.
6. The Ethernet Status LED changes states depending on the status
of the Ethernet network as described in the section
Communications o
n page 67.
Communications
All drive/controller communications are based on Ethernet. The Aries
Controller may be connected directly to any appropriately configured
Ethernet port. The drive IP address will be 192.168.100.xx, where xx is
defined by the address selection switches on the unit’s front panel.
RJ-45 Ethernet Status LEDs
The first step in troubleshooting communications is to observe the state of
the RJ-45 Ethernet Status LEDs. (Figure 37 shows their location on the
drive’s
dual-stack RJ-45 socket.) These LEDs indicate any Ethernet
connection, as described in Table 28. Note that for a standard 100Mbps
con
nection, both the yellow and green LED should be illuminated. For a
10Mbps Ethernet connection, the Yellow LED should be illuminated and the
Green LED off.
