12. © Copyright IBM Corporation 2006 12 JS21 - Memory The BladeCenter JS21 supports: ●Double Data Rate (DDR) ECC Registered SDRAM memory ●4 DIMM slots, populated in matched pairs ●The installed DIMMs on a BladeCenter JS21 must be all PC2-3200 (400 MHz) or PC2- 4200 (533 MHz). A mix of the two is not supported in a single BladeCenter JS21. ● A pair of installed DIMMs must be the same size.

13. © Copyright IBM Corporation 2006 13 PCI-Express –Point to point serial interconnect with packetized, layered protocol –2.6 Gbits/s per-pin pair in each direction (speed scale in future generations) – Dual simplex connection – Scalable bus widths – Embedded clocking technique using 8 bit/10 bit encoding – Isochronous Data transfer support – Compatible with PCI at the software layers PCI-Express (PCI-E) is the successor to PCI and PCI-X bus systems, realized by point-to- point implementation with the following general characteristics:

16. © Copyright IBM Corporation 2006 16 JS21 - Diagnostics Tools ●Light Path Diagnostics ●Power-on self-test (POST) –Firmware checkpoints and error codes The firmware checkpoints are progress codes that your blade server displays during POST. ●Firmware error codes and location codes –Some firmware error codes also include location codes. The location code information is required to identify the failing component. ●Diagnostic utilities for the Linux and AIX operating systems –Available from IBM http://www.ibm.com/servers/eservers/support/bladecenter/ ●To run stand-alone diagnostics you must establish a Serial Over LAN (SOL) connection and start an SOL session on the blade server. Then you can: –Run stand-alone diagnostics from CD-ROM –Run stand-alone diagnostics from management (NIM) server
