Chapter 6: Operation

6.2 Reset Switch

Figure 6-4 shows the location of the Reset switch on the LES421A, LES422A, and LES424A Hardened Serial Servers.

Reset Switch

Figure 6-4. Left: top view of the LES421A or LES422A; Right: back view of the LES424A.

The Reset switch is used to:

• Initiate a hardware reset.
• Enter Console mode.
• Reload factory defaults.

6.2.1 Using the Reset Switch to Initiate a Hardware Reset

Hold the Reset switch in for 0 to 2 seconds. The P1 LED illuminates while the switch is being held in. Release the switch in less than two

seconds or the Hardened Serial Server will enter Console Mode.

6.2.2 Using the Reset Switch to Enter Console Mode

Hold the Reset switch for between two and ten seconds. The P1 LED illuminates for the first two seconds and the P1 LED goes out, then

the P2 LED illuminates until the Reset switch is released. Release the switch in less than 10 seconds or the Hardened Serial Server will

reset to factory default settings. The Hardened Serial Server will re-boot and enter Console Mode. LED P1 will be on while the unit is in

Console Mode.

6.2.3 Using the Reset Switch to Exit Console Mode

Press the Reset switch for less than two seconds, or remove power from the Hardened Serial Server, wait a few seconds, and turn the

power on again. The LEDs go back to their normal states when the device resumes normal operation.

6.2.4 Using the Reset Switch to Reload Factory Default Settings

Hold the Reset switch for more than ten seconds. The P1 LED illuminates for the first two seconds; then the P2 LED illuminates. After

10 seconds the P1 and P2 LEDs will illuminate. When the switch is released, both the P1 and P2 LEDs will go out. The Ready LED will

flash quickly while the Hardened Serial Server re-initializes to factory default settings, and then the server will re-boot.
