Installation and Getting Started Guide
NOTE: The 802.3ab standard calls for automatic negotiation of the connection between two 1000BaseT ports.
Consequently, a crossover cable may not be required; a straight-through cable may work as well.
Connecting to Workstations, Servers or Routers
Straight-through UTP cabling is required for direct UTP attachment to workstations, servers, or routers via network
interface cards (NICs).
Fiber cabling with SC connectors is required for direct attachment to Gigabit NICs or switches and routers.

Troubleshooting Network Connections

For the indicated port, verify that both ends of the cabling, at the Routing Switch and the connected device,
are snug.
Verify the connected device and the Routing Switch are both powered on and operating correctly.
Verify that you have used the correct cable type for the connection:
For twisted-pair connections to an end node, use straight-through cabling.
For fiber-optic connections, verify that the transmit port on the Routing Switch is connected to the receive
port on the connected device, and that the receive port on Routing Switch is connected to the transmit
port on the connected device.
Verify that the port has not been disabled through a configuration change. You can use the CLI or if you have
configured an IP address on the Routing Switch, you can use the Web management interface.
If the other procedures don't resolve the problem, try using a different port or a different cable.
Verifying Proper Connections
After you install the network cables, you can test network connectivity to other devices by pinging those devices.
You also can perform trace routes.
Pinging an IP Address
To verify that an HP device can reach another device through the network, enter a command such as the following
at any level of the CLI on the HP device:
HP9300> ping 192.33.4.7
Syntax: ping <ip addr> | <hostname> [source <ip addr>] [count <num>] [timeout <msec>] [ttl <num>] [size <byte>]
[quiet] [numeric] [no-fragment] [verify] [data <1-to-4 byte hex>] [brief]
See the Command Line Interface Reference for information about its parameters.
NOTE: If you address the ping to the IP broadcast address, the device lists the first four responses to the ping.
Tracing a Route
To determine the path through which an HP device can reach another device, enter a command such as the
following at any level of the CLI on the HP device:
HP9300> traceroute 192.33.4.7
Syntax: traceroute <host-ip-addr> [maxttl <value>] [minttl <value>] [numeric] [timeout <value>]
[source-ip <ip addr>]
The CLI displays trace route information for each hop as soon as the information is received. Traceroute requests
display all responses to a given TTL. In addition, if there are multiple equal-cost routes to the destination, the HP
device displays up to three responses by default. See the Command Line Interface Reference for information
about the command syntax.
