3.4.1.3 DCD/DSR Signal Select Jumper
Note: This jumper affects the rear panel serial port only.
Various serial port concentrators may require either the DCD (Data Carrier Detect) or DSR (Data
Signal Ready) signal on Pin 7 of the RJ45 connector. To allow support for either of these two serial
port configuration standards, a jumper block (J8A3) located directly behind the rear RJ45 serial port
(see Figure 21 ) must be configured appropriately according to the desired standard:
• For configurations that are compatible with Cisco serial concentrators and require a DSR signal,
the jumper block must be configured with the serial port jumper over pins 3 and 4. This is the
factory-installed default setting for this jumper.
• For configurations that are compatible with many modems and other serial devices that require a
DCD signal, the jumper block must be configured with the serial port jumper over pins 1 and 2.
Pin 1 on the jumper is identified by “ ”.

3.4.2 Configuring Memory DIMMs
The memory DIMM sockets are located on the T5000PAL server board at the rear right portion of the
TIGH2U Server chassis. See Figure 22 for the location of the DIMM sockets. The silkscreen on the
board for the DIMMs displays DIMMA1, DIMMA2, DIMMA3, DIMMB1, DIMMB2 and DIMMB3, starting
from the inside (left side) of the server board. DIMMB3 is the socket closest to the outside edge of the
server board.
The Memory Controller Hub (MCH) on the T5000PAL server board provides for four channels of Fully
Buffered DIMM (FB-DIMM) memory. Each channel can support up to two Dual Ranked FB-DIMM DDR2
DIMMs. FB-DIMM memory channels are organized into two branches for support of RAID 1
(mirroring). The MCH can support up to 8 DIMMs for a maximum memory size of 32 Gbytes of
physical memory in non-mirrored mode and 16 Gbytes of physical memory in a mirrored
configuration.
For DDR2 533 FB-DIMM memory, the read bandwidth for each FB-DIMM channel is 4.25 Gbytes/s,
which gives a total read bandwidth of 17 Gbytes/s for four FB-DIMM channels. This provides 8.5
Gbytes/s of write memory bandwidth for four FB-DIMM channels.
For DDR2 667 FBDIMM memory, the read bandwidth for each FBDIMM channel is 5.3 Gbytes/s, which
gives a total read bandwidth of 21 GBytes/s for four FBDIMM channels. This provides 10.7 Gbytes/s of
write memory bandwidth for four FBDIMM channels.
