the Enter key. If you can properly access and operate the chosen CPU, the second-tier Base Unit

is properly installed.

m. Repeat steps c through l for all remaining (if any) second-tier Base Units attached to the master

Base Unit.

n. Edit the names of any server CPUs directly attached to the master Base Unit and verify the master

Base Unit’s configuration as described in steps 6b through 6e of the section Installing a Paragon

II with a Single Base Unit, earlier in this chapter.

Important! If you rearrange a cascaded system or dismantle one and rebuild it

differently later, you must recycle power to each Base Unit in the new cascade. A soft

reset allows each Base Unit to retain all user and system profiles, and to auto-detect

the current status of its channel port and user ports. Follow the installation steps in

this section to install the new cascade, but when you power on each Base Unit (which

must be done in proper tier order, from base tier to upper tier), press the FUNC and the

 buttons on the unit’s front panel until “Reset Unit” appears on the LED panel. Press

the ENT button to reset the unit. Starting with a subsidiary Base Unit in the third tier (if

there is one), power on the unit, press FUNC and  until the LED panel flashes, then

press the ENT button, and wait until the LEDs cycle through and return to their original

state. Repeat for any other third-tier units, then all second-tier units, and finally the

master unit.
