Power requirements for Alcatel ADSL 4-port router

I have a 4-port Alcatel ADSL router with a MTC 150 chipset that I purchased in Belgium to connect to my local ISP.  I'm trying to find out what its power requirements are, since I now wish to hook it up/test it to see how it may perform with my local ISP in the US.  I can't find any information/tech specs about this router on the Alcatel website or the web.  It has a power outlet to an external power supply which I left behind and no power requirements are labeled. There is some information on the label (which may include a part number) and some information which I kept on the software,  if that would help to solve this problem.  Can you help?

I junked the transformer based heavy cubes long time ago. Just use slim line regulated switching 12V/1.5A,  5V/3A, 7V/2A cubes for most equipment. Sometimes an adapter is needed for an odd sized plug.

The switchable ones were unregulated with transformer taps.
The 300mA is too small.
Typically 12V/1.5A supply with + in the center will work.

I found the manual!  It lists the power requirement as a 9Vdc/ 1.5 Ampere
Thanks for your reply, which leads me to a related question:
I have a switchable power supply which goes up to 12V at max 300 mA, but
even though it has a 9V setting, 300mA = .3A < 1.5A, so it won't be enough amperage, right?

I'm now using this switchable power supply to provide 7.5Vdc to my hub.  I also have a power supply (for digital cameras) which goes up to 7.5V, but its amperage is at 2.0A > 1.5A, so this could fry the hub, right?

In conclusion, how much leeway do I have on voltage or amperage before I damage something?
