Unpacking and Installing Your ELS10-26
4. Once the ELS10-26 is installed, plug the AC power cord into
the AC power connector on the rear of the ELS10-26 chassis.
Plug the other end of the power cord into a three-prong
grounded outlet.
2.4 CHECKING THE POWER-UP DIAGNOSTICS
SEQUENCE
Before connecting any devices to the ELS10-26, power on the unit
and observe the power-up diagnostics sequence to check for
proper operation.
To observe the power-up diagnostics sequence completely, you
may want to repeat it. To restart the power-up sequence, press the
reset button on the front panel.
When you power up the ELS10-26, the following occurs:
1. All LEDs, except the Port Link LEDs, turn on for one second.
2. The Power (Pwr) LED remains on.
3. The CPU LED starts flashing.
4. After several seconds, the Port Link LEDs turn on,
individually, in sequence, from left to right until all are lit,
then go off.
5. After several more seconds, the Ready LED will stay on,
indicating that the power-up diagnostics sequence is
complete.
6. In addition, the Port Link LEDs will turn on for those ports
with good links and the Segment Status LEDs will turn on (or
flash) when the selected status condition is present.
Note: If a critical component fails diagnostics, the CPU LED will turn off
and the ELS10-26 will attempt to reboot. If the CPU LED does not
stay on, contact Cabletron Systems Global Call Center. Refer to
Section 1.2.
