9. Repeat steps 6 through 8 for the remaining modems
(devices).
10. If necessary, refer to the modem (device) Owner's Manual
for connecting the cables and telephone lines to the
modems (devices).
11. When all the modems (devices) are connected to the
computer and the telephone lines, plug the AC power cord
supplied with the rack into the power cord connector on
the back of the rack and to a live AC outlet.
Powering Up
Once power is applied to the rack, the modems perform a
diagnostic self-test, indicated by the speed LEDs flashing in
sequence for approximately two seconds, then the 96, 14, 28,
33, or 56 (depending on the type of device installed) should
light. If none of the modems have power applied to them,
check the power cord connection to the rack, then check that
the AC outlet is live. If one or more modems do not power up,
check the power connections to them.
If one of the green power supply LEDs on the front of the rack
is not on, then one of the redundant power supplies may be
defective (or disconnected from input power).
