Installing the HSSI Module

Installing the HSSI Module

Use this procedure to install the HSSI module into the NETBuilder II base system. You will
need a small flathead screwdriver.

NOTE:

There are two versions of the NETBuilder II 4-slot and 8-slot chassis. The older, single-

wide versions of the NETBuilder II 4-slot and 8-slot chassis have two flipper ejectors for each
module. The newer, dual-wide versions have one flipper ejector for each module, except for the
top slot which is reserved for the CEC module. When the term “dual-wide NETBuilder II
chassis” is used in this manual, it refers to a chassis with only one flipper ejector per module.

Select an I/O slot in which to install the HSSI module.

You can install the module in any available I/O slot in the rear of the NETBuilder II base
system. The top slot is designated for the CEC module only.

Remove the blanking plate from the I/O slot you have selected for the HSSI module.

CAUTION:

Only remove the blanking plate from an I/O slot that will house an I/O module. All

unused I/O slots require blanking plate covers to maintain proper cooling of the unit and
regulatory compliance. Failure to cover open slots can result in overheating of the NETBuilder
II base system and voiding of the warranty.
