IBM 8677 manual Features and specifications

Notes:

1. For details about the BladeCenter unit port specifications, see “Input/output connectors” on page 26.

2. For information about which types of I/O modules can be installed in which I/O-module bays, see “I/O modules” on page 16.

3. The operating system in the blade server must provide USB support for the blade server to recognize and use the keyboard, mouse, CD-ROM drive, and diskette drive. The BladeCenter unit uses USB for internal communication with these devices.

– Power modules 1 and 2 provide redundancy to each other

– Power modules 3 and 4 provide redundancy to each other
