Possible Cause
If using iSCSI connections, connect a category 5e or
category 6 LAN cable to the RJ-45 connector marked
LAN and the management console
1. Check the array power cables, power sources,
2. Check whether other devices in your network,
3. Turn off the array. Verify that the front panel
4. Turn on the array, wait about 4 minutes for the

Set a suitable value for the customer's environment
for the IP address, subnet mask, and default gateway
of array.
[default value]
controller #0:
IP address:192.168.0.16
default gateway:0.0.0.0
Subnet Mask:255.255.255.0
controller #1:
IP address:192.168.0.17
default gateway:0.0.0.0
subnet mask:255.255.255.0
When the same IP address as the other arrays or
hosts is set for the array, Navigator 2 cannot be
connected correctly to the array. Set the array IP
address to one that is not used by any other array or
hosts on the LAN.

power switch, and Power LED.
such as a router or switch, are the cause of the
problem.
Power LED goes OFF. If the Power LED stays ON,
disconnect both power cables and verify that the
front panel Power LED is OFF.
POST to complete, and verify that the Ready LED
goes ON.
Array or part has failed, above.
When the array is set to use the DHCPv4 server,
connect with the IP address assigned by the
DHCPv4 server. When using the DHCPv4 server, it
is recommended that the array be set to statically
(Static) assign IP address.
If the IP address is not assigned from the DHCPv4
server to the array when the array is set to use
the DHCPv4 server, Navigator 2 cannot be
connected to the array. Consult with your network
administrator, and review the DHCPv4 server
settings.
The default value is DHCPv4:Off (uses a Static IP
address)
The standard default TCP port number for
Navigator 2 is 2000. The secure port is 28355. Set
a suitable value for the customer's environment.
Be sure to change the port number in the
environment using the Cisco SIP Phone.
