CAUTION:
An electrostatic discharge (ESD) wrist strap with a resistance
between 250 K and 1.5 M ohms should be worn when handling the
SLC ConnectReach system interface cards or motherboard to
prevent damage. Before using the wrist strap, check it for shorts,
opens, and proper resistance value. If the strap does not pass these
checks, it should not be used. To avoid possible personal injury
while using the wrist strap, do not connect it to any power source or
shelf housing a power source.
Use a Phillips screwdriver to remove the screw from the center of the SLC
ConnectReach system front panel.

the bottom tray/front panel assembly forward, separating it from the top
and side cover.

package of hardware from the packing carton. The hardware package
