Chapter 3. Planning 83
If the RXE-100 has the second set of six PCI slots installed, use the short
interconnect management cable (supplied with the PCI slot option kit) to
connect Management A (out) Port to Management B (in) Port (see Figure 3-9
on page 81).
The 8 m interconnect management cable is suitable for inter-rack
configurations.
For 16-way configurations, the management ports must be connected as
shown in Figure 3-10 on page 82. An additional cable will need to be ordered.
3.2.4 Serial connections
The x440 does not have an external serial port. If a serial port is required (for
example, for UPS remote management), then a USB-to-serial adapter is
required, such as the Belkin USB to Serial Adapter (part number 10K3661).
It is also possible to configure the serial port on the Remote Supervisor Adapter
to be sharable between the alerting functions of the adapter and the operating
system. However, we recommend that you use a separate serial port.
3.3 Storage considerations
When you are planning the storage configuration to accompany the x440, there
are important performance and sizing issues that need to be considered.
The two internal hot-swap 1” drive bays will typically be used for operating
system installation. We recommended these drives be configured as a two-drive
RAID-1 array to provide a higher degree of system availability. Drives up to
Important: In the publication
IBM RXE-100 Remote Expansion Enclosure
Installation Guide
, the section entitled “Attaching the enclosure to an
xSeries 440 server” does not include instructions to connect the ports
Management A (out) and Management B (in) on the RXE-100. Our testing
in the lab indicates that this additional cable is necessary.
Important: Power to the RXE-100 is controlled by the x440, via the
interconnect management cable and under the control of the Remote
Supervisor Adapter.
Restriction: IBM USB Serial/Parallel Adapter (part number 22P5298) is not
supported in the x440.
