Best practices for integrating cable and system placement

These guidelines ensure that your system and its cables have optimal clearance for maintenance and
other operations. The guidelines also provide guidance for correctly cabling your system and using the
appropriate cables.
The following guidelines provide cabling information for installing, migrating, relocating, or upgrading
your system:
v Position drawers in racks to allow enough space, where possible, for cable routing on the bottom and
top of the rack, and between drawers.
v Shorter drawers are not be placed between longer drawers in the rack (for example, placing a 19-inch
drawer between two 24-inch drawers).
v When a specific cable plugging sequence is required, for example, for concurrent maintenance
(symmetric multiprocessing cables), label the cables appropriately and note the sequence order.
v To facilitate cable routing, install cables in the following order:
1. System power control network (SPCN) cables
2. Power cables
3. Communications (serial-attached SCSI, InfiniBand, remote input/output, and peripheral component
interconnect express) cables
Note: Install and route the communications cables, starting with the smallest diameter first and
then progressing to the largest diameter. This applies to installing them into the cable management
arm and retaining them to the rack, brackets, and other features that may be provided for cable
management.
v Install and route the communications cables, starting with smallest diameter first and then progressing
to the largest diameter.
v Use the innermost cable-management bridge lances for SPCN cables.

Recovery steps
1. Verify that line cords are plugged in correctly in the
following locations:
v Drawer
v Power distribution unit (PDU), if applicable
v Battery backup unit (BBU), if applicable
v Input source power receptacle
2. Verify that the power supplies are seated and latched
into position.
Ensure that you are using the correct power voltage.
Refer to your server's specifications to learn more about
the power voltage that your server requires.
These errors are often caused by ports that are not used.
Every port must have a cable or wrap plug installed.
Whenever a cable is not installed, ensure a wrap plug is
installed for each unused port. Wrap plugs are shipped
automatically when a Fibre Channel feature code is
ordered.
Ensure that you have entered the correct IP address.
