Caution! Avoid redundant connections. Ensure there is no signal conflict between SCSI pins and the
associated header pin (J5, J7, and J8). Also make sure there is no conflict between theTB7 TC
connections and the SCSI and/or the 40-pin header connections.
Failure to do so could possibly cause equipment damage and/or personal injury.
Also, turn off power to all devices connected to the system before making connections. Electrical
shock or damage to equipment can result even under low-voltage conditions.
Information on signal connections
General information regarding signal connection and configuration is available in the Guide to Signal
Connections. This document is available on our web site at

Caution! Always handle components carefully, and never touch connector pins or circuit components unless
you are following ESD guidelines in an appropriate ESD-controlled area. These guidelines include
using properly-grounded mats and wrist straps, ESD bags and cartons, and related procedures.
Avoid touching board surfaces and onboard components. Only handle boards by their edges. Make
sure the USB-2527 does not come into contact with foreign elements such as oils, water, and
industrial particulate.
The discharge of static electricity can damage some electronic components. Semiconductor
devices are especially susceptible to ESD damage.
