Unpacking and Installing Your ELS100-16TX

4.Once the ELS100-16TX is installed, plug the AC power cord into the AC power connector on the rear of the ELS100-16TX chassis. Plug the other end of the power cord into a three- prong grounded outlet.

2.4CHECKING THE POWER-UP DIAGNOSTICS SEQUENCE

Before connecting any devices to the ELS100-16TX, 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 ELS100-16TX, the following occurs:

1.The Power (Pwr) LED is on.

2.The CPU LED starts ﬂashing. Two of the Port Status Mode LEDs are on.

3.After several seconds, the CPU LED will stay on and only one Port Status LED is lit. This indicates the power-up diagnostics sequence is complete.

Note: If a critical component fails diagnostics, the CPU LED will turn off and the ELS100-16TX will attempt to reboot. If the CPU LED does not stay on, contact the Cabletron Systems Global Call Center.

Refer to Section 1.2.

2.5 CONNECTING THE LOCAL CONSOLE MANAGER

The Local Console Manager (LCM) is a command-line interface for conﬁguring, monitoring, and managing the ELS100-16TX through the out-of-band RS232C connection on the front panel.
