I have MSE 8000 and 2 Eltec Valere rectifiers. How to connect rectifiers to the MSE? Rectifier have two output marked "Positive" "Negаtive" and MSE8000 have two input marked "-48V" and "RTN". I guess that I must connect -48V to Negative and RTN to Positive, but I am not sure and MSE8000 cost very expensive...and I'm afraid to make a mistake. In getting started guide it is not clear. And another question about serial connecrion between MSE8000 supervisor and rectifiers. Where is serial port placed on rectifiers and how is it marked? Is it LAN port on the back of the rectifier?
The MSE 8000 Getting Started Guide covers everything you're looking for, starting on page 18 on connecting the power. The getting started guides has diagrams and notes what each cable is.
The serial cable plugs into the back of each power shelf, there is a port on the back of the power shelves between two of the power outlets, see page 19 of the guide, and that plugs into the two serial ports on the back of the MSE 8000.
If you haven't figured it out in the next few days, etc, and I'm out at our data center, I'll take a few pictures of ours for reference.
The color coding of DC power cables is not generally standardized. Cisco supplies one black and one red cable with each power shelf. Unless national or local regulations apply, assign these to the -VDC and RTN connections according to usual practice at your facility.
The short answer is that you don't.... That isn't entirely true while at
the same time it kind of is, but for the most part you don't configure
the softkeys. You enable or disable them via TCL. Here is the long
answer. Be sure to read the whole thing or e...
