There are a few things that you can do. First; try to go online to HewlettPackard.com and locate the power supply. Second;go online to ebay and search for the power supply. Last;locate a Batteries R Us store in your city. They have a huge supply of batteries and power adapters. If you do not find a HP adapter the store person can help you find one that is complimentary to your HP adapter.

You may have a bad ethernet cable. I would try the easy thing first and just go to Best Buy, Amazon etc... and purchase a new RJ45 CAT5 or CAT6 ethernet cable. Since you are receiving an orange light it is indicating that the port is not active. Also check the cable make sure its seated properly at both ends even with a new cable. Cheers! Hope it helps!

I am looking for the hotkey combination for our HP 336044-b21 KVM switch from a iogear KVM?


IOGEAR KVM switches uses Scroll Lock for the hot key. The models of IOGEAR KVM switches starts the letters "GCS". I don't think that your HP 336044-b21 came from IOGEAR.

Anyway, if that's an IOGEAR KVM switch, you may quickly press Scroll Lock twice + Enter (for two port KVM).

Scroll Lock twice + port # + Enter (for 4 port, or 8 port KVM).

NOTE: You need to verify the brand of your KVM switch by referring to the user manual of it.

Thank you and good luck!

Need a power supply for Beyond Micro BMMDU2 drive. What is the voltage and current rating? Also, has this company been rebranded?


Mine came with a "DVE Switching Adapter":

(Model: DVS-120A15FUS
Input: 100-240V ~ 50/60Hz 0.7A)

Output is +12V, 1.5 A

Diagram indicates that the outer shield is negative, I think.

Switching power supply ??


For your purposes there is no difference: all you need to know is the voltage your WD drive requires, and the maximum current load it needs. Any regulated DC power supply with that voltage and *at least* that current will do.

Not-so-technically, a "regular" power supply will supply power at the correct voltage by "discarding" a portion of the extra potential. A "switching" power supply will shunt and switch the extra power away, so that instead of being "lost", it is "not requested" from the uplink grid. In theory a perfect switching supply will have no losses, and therefore dissipate no waste heat (in practice there will be some losses, and cooling will be needed). The important thing, though, is that a switching power supply can deliver twice as much power as a "normal" supply, and the same power in a half as big package.
