7. Connect the Network Devices

The type of network connections you will need to use depends on the types
of switch modules you have installed in your Switch 4000M and 8000M. See
the documentation accompanying the modules for cabling configurations and
procedures for those modules.
The module documentation will also cover troubleshooting procedures, but,
in general for all the modules, when a network cable from an active network
device is connected to the switch module port, the Link LED for that port
should go on. If the Link LED does not go on when the network cable is
connected to the port, use the table below to help solve the problem.
Condition Diagnostic Tip
Port LED is Try the following procedures:
still off when
• For the indicated port, verify that both ends of the cabling, at the switch and the connected
a cable is
device, are snug.
connected
• Verify the connected device and switch are both powered on and operating correctly.
• Verify that you have used the correct cable type for the connection.
- for twisted-pair connections, in general, for connecting to an end node, use "straight-
through" cable; for connecting to hubs or other switches, use "crossover" cable.
- for fiber-optic connections, verify that the transmit port on the switch is connected to
the receive port on the connected device, and the switch receive port is connected to
the transmit port on the connected device.
• Verify that the port has not been disabled through a switch configuration change.
You can use the console interface, or, if you have configured an IP address on the switch,
use the web browser interface, or HP TopTools for Hubs & Switches network management
software to determine the state of the port and re-enable the port if necessary.
• If the other procedures don't resolve the problem, try using a different port or a different
cable.

Plug the included power cord into the switch's power connector and into
a nearby properly grounded AC power source.
If you have installed a redundant power supply module into the switch, it
should be connected to a separate AC power source. Then, if there is a
power outage from one of the AC sources, the switch will continue to
operate by power coming from the other source.
See the HP ProCurve Switch 4000M/8000M Power Supply Installation
Guide for additional information.
Re-check the LEDs during self test. See "LED Behavior" on page 2-9.
