Troubleshooting the Agilent 82357B

Hardware Checks

If all LEDs are still off for 10 or more seconds after plugging
the 82357B USB cable into a USB port, and all Windows
Plug- and- Play Manager activity and the

Connection Expert

refreshes have ceased, start your troubleshooting sequence
by performing hardware checks. If any action taken results
in a change in the LED status, go to

Software Installation

Checks

or

Software Configuration Checks

.

Check USB cables, USB interface, host PC

Begin the hardware check by checking connections between
the 82357B and PC (plus USB hubs, if used).

1

Check USB cable connections.

Check the 82357B USB

cable for a good connection to the USB port on the PC or
on the USB hub. If you are using a USB hub, verify that
the hub is connected to the PC.

2

Unplug/replug the 82357B USB cable.

If this does not

change the LED status, try plugging the 82357B into
another USB port.

3

Check PC USB Port.

Verify that the PC USB port is

functional and powered (you can check using another USB
device).

4

Check PC state.

Verify that host computer is not in a

suspended power management state.

5

Check USB hub.

Try disconnecting the 82357B from the

hub and connecting it directly to a USB

port on the PC.

Some USB hubs are vulnerable to static shock.

6

Check USB cables for damage.

Check the USB cable for

cuts/crushes. Since the end connectors are somewhat
fragile, check for bent/misaligned/crushed connectors.

Reboot PC

If these steps do not change the LED status, reboot the PC.
