N1200-320 4Gb Network Storage Router user and service guide 95
8Troubleshooting
Various problems can arise when configuring and using the HP N1200-320 4Gb Network Storage Router.
This section is provided to help guide the user through some of the basic methods of identifying faults in the
setup and configuration of the network storage router.
Most problems are found in the initial installation. In general, it is wise to check all connections and review
the configuration before proceeding with further trouble analysis. Simplify the installation if possible,
reducing it to the most basic configuration, then adding elements one at a time and verifying the operation
at each step.
General troubleshooting
What happens if the DHCP server cannot be contacted?
• Serial Interface: the following occurs over the serial line: the following text appears above the HP
Systems Main menu within the terminal window, “Attempting to contact DHCP server…” After about 3
minutes, the following message appears, “Can’t renew DHCP boot lease.”
• Within Telnet: the user will see only a blank Telnet window which is not accessible. Instead of an IP
address value displaying in upper left heading of Telnet window, “(None)” appears instead. Within
half a minute, Telnet will produce a warning message stating “Connect Failed!”
• Within Visual Manager: the user will be able to submit a new Web page and reboot (as is typically the
case). However, since the DHCP isn’t contacted, a new IP address will not be generated after reboot.
Therefore, Visual Manager will no longer be useful since no IP address is available. The previous
non-DHCP will not work either. Visual Manager will time out and provide a warning message to the
user stating that “a connection with server could not be established.”
In the above situations, perform the following:
1. Check on the status of the DHCP server with your network administrator,
2. Ensure the Ethernet link (LNK) light on the network storage router is green (and if not check that the
Ethernet cable is securely connected).
3. Check the configuration of the network storage router, including the gateway address, and assign
values manually, if needed.
If the above list all appear to be in order, but DHCP is still not working, attempt to reset the network
storage router to factory defaults (any current configuration settings will be reset), reboot the network
storage router, and then reconfigure the network storage router as desired. If problems persist, see
”Technical support” on page 99.
Indicators
The network storage router is equipped with LED indicators for monitoring overall unit status (see Figure 74
on page 96). The LED functionality of the network storage router is detailed below:
• Power and Fault (PWR)—This indicator is a bi-color LED. When green, this indicator shows that power
is currently active. Lack of power indication suggests that the unit is turned off, a problem with the
power supplied to the unit, or an internal problem with the unit. When this indicator is amber, this
indicator shows that the network storage router detects a fault condition. Faults can occur as a result of
Power On Self Test (POST) failure or operational failures. It is normal for this indicator to flash on when
the unit is powered up or reset. If the fault indicator stays lit, contact your product support
representative.
• Fibre Channel (LNK/ACT)—When green, the LNK indicator signifies a good Fibre Channel link on the
port. When green, the ACT indicator signifies Fibre Channel port activity. If the LNK indicator fails to
light at all, or if the ACT indicator stays continually lit without corresponding activity on a FC device
port, there may be a problem with the Fibre Channel configuration. Verify the Fibre Channel
configuration.
• SCSI Bus (0, 1)—When lit, these green indicators signify SCSI activity on the bus corresponding to the
number of the indicator. Activity should only occur briefly during power-up or configuration, and
relatively often when the unit is transferring data. If an ACT indicator stays continually lit without
