Port Purpose
7
1 Gbps Ethernet ports, left is port 1,
right is port 2
1 GB file module-to-file module interconnect
8
1 Gbps Ethernet ports, left is port 3,
right is port 4
1 GB external network connection
2
10 Gbps Ethernet ports, right is port 0,
left is port 1
10 GbE external network connection
If you are looking at a problem regarding built-in Ethernet port 1 or built-in
Ethernet port 2, refer to “Ethernet connectivity between file modules.”
Isolation procedures:
Ensure that the file module is powered up before you begin this procedure. The
network connection being diagnosed must be connected to an active port on your
Ethernet network.
v
Determine the state of the Ethernet LEDs examining the LEDs of the Ethernet
ports.
v
The activity LED flashes when there is activity on the connection. The link state
LED must be permanently on. If it is off, the link is not connected.
If your link is not connected, perform the following actions to check the port status
each time until it is corrected or connected:
1. Verify that each end of the cable is securely connected.
2. Verify that the port on the Ethernet switch or hub is configured correctly.
Contact your network administrator to verify the switch and network
configuration information.
3. Connect the cable to a different port on your Ethernet network.
4.
Replace the Ethernet cable.
5. For the 10 GbE Ethernet port, replace the small form-factor pluggable (SFP)
transceiver. Refer to “Removing a PCI adapter from a PCI riser-card assembly”
on page 102 and “Installing a PCI adapter in a PCI riser-card assembly” on
page 103.
Ethernet connectivity between file modules
This topic covers troubleshooting network connectivity issues between the file
modules. These connections are used for internal management operations between
the file modules.
This procedure is used to troubleshoot Ethernet network connectivity between both
of the file module. These network paths are used for all internal system
communication. Between both file module, there are two separate network paths
for internal communication, two separate network paths
