Communications
All drive communications are based on Ethernet or EPL. When the drive is
attached to the ACR9030 or ACR9040 EPL controller, and the EPL network
is established, all communications takes place through the ACR9030 or
ACR9040 EPL controller. Each Aries EPL drive attached to the EPL network
can be accessed through the ACR9030 or ACR9040 EPL controller.
Alternatively, an Aries EPL drive 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
drive’s front panel.
EPL Drive Ethernet Status LEDs
The first step in troubleshooting communications is to observe the state of
the Ethernet status LEDs. (Figure 46 shows their location on the drive’s EPL
RJ-45 socket.) These LEDs indicate any Ethernet or EPL connection, as
described in Table 80. Note that for an EPL connection or a standard
100Mbps connection, 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.
Figure 46 Ethernet Status LEDs
LED Steady Flash Description
Off — No Ethernet link detected
Yellow — Ethernet link established,
no activity
Ethernet Link/Activity
— Yellow Ethernet link established
and active
Off — Ethernet 10Mbps Ethernet Speed
Green — Ethernet 100Mbps

If neither Ethernet Status LED is illuminated, the physical Ethernet
connection is faulty.
