Installing the
Module in an
Extended Chassis
You can install up to seven HSS RS-232 modules into a NETBuilder II 8-Slot Extended
chassis.
You will need a small flat-blade screwdriver.
You can safely install a module without turning off or rebooting the NETBuilder II
system.
To install the module into a NETBuilder II 8-Slot Extended chassis, follow these steps:
1 Remove the card carrier from the I/O slot you have selected.
The card carrier acts as a filler panel when a module is not installed.
You do not need to remove the cable strain-relief bracket that came with your
NETBuilder II chassis.
a
Loosen top and bottom
captive screws with a
screwdriver. Do not
loosen center captive
screw.
b
Push ejector tabs apart
c
Slide card carrier
out of chassis
WARNING: Only remove the card carrier from the I/O slot that will house the RS-232
3-Port module. All unused I/O slots must be covered by a card carrier 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.
2 Install the module onto the card carrier.
