Questions about this item

How much power does the 44W4404 module draw when running continuously in a BladeCenter chassis?

The module operates from the chassis backplane, so total draw depends on the BladeCenter power supply configuration and the number of active uplink ports.

What chassis and slot type are required to install the 44W4404 switch module?

It fits the I/O module bays of a BladeCenter E or BladeCenter T chassis; up to four modules can be installed side by side.

Can the 44W4404 uplink module connect to existing 1 GbE servers in the same BladeCenter?

Yes, its six RJ-45 ports run at 1000Base-T, so they link directly to 1 GbE blade servers already installed in the chassis.
