Installing Peripheral Devices

When you add additional storage devices, refer to the Rackmount Placement Matrix, at
http://docs.sun.com for mounting hole numbers for mounting screws for Sun
disk arrays and other storage trays and devices.
Unless otherwise specified in the Rackmount Placement Matrix, mount the heaviest
subassemblies at the lowest available opening to minimize the effects of
earthquakes.
Refer to the installation guide for the peripheral device for additional instructions.

cPCI Card Visibility Issues

Note – Make sure to leave at least 1
connection. This facilitate removal or installation of adjacent adapters.
The visibility of Slot0 and of any adapter connectors in this slot is reduced. Exercise
suitable caution while cabling, and/or observing the Hot-swap indicators on the
card and I/O assembly.
When cabling adapters with double connectors, note that some adapters reverse the
orientation and keying of the connectors between the pair. A cable attached to one
connector will be rotated a half turn to attach to the other connector and this may
not be obvious under the visibility conditions at the I/O assembly.
When attaching two cables to adapters with double connectors, one above the other,
cabling the lower port first will provide greater visibility of the connector.
When removing adapters with double connectors and particularly with heavy cables
(like SCSI), it is recommended that both cables be disconnected from the adapter
before attempting adapter Hot-Removal from the I/O assembly. This eases the
removal effort and reduce the likelihood of damage to the cards and cables.
