Cabletron Systems SEHI100TX-22 manual Using The Reset Button

Chapter 6: Troubleshooting

CPU

This LED alternates from red to green to during power up. After the boot is complete, the LED blinks green. A blinking green LED indicates normal operation. A red LED indicates a faulty processor.

CLN

When this red LED flashes, it indicates that a collision has occurred on one of the ports.

RCV

When a yellow RCV LED flashes, it indicates that the SEHI is receiving data packets from the associated port segment. Each SEHI port has a corresponding RCV LED:

• Network Ports: RCV LEDs		1-22
•	EPIM 1: RCV LED	E
•	Management: RCV LED	A

LNK

When a green LNK LED is on, it indicates an established link between the associated port and the device at the other end of the segment. The LNK LED remains on as long as a link is maintained. Each SEHI Network Port (ports 1 through 22) has a corresponding LNK LED.

6.3USING THE RESET BUTTON

The SEHI incorporates a recessed RESET button. See Figure 6-1. The RESET button initializes the SEHI processor. This button does NOT initialize Non-Volatile Random Access Memory (NVRAM), the nonvolatile random access memory where the SEHI stores network management parameters.

To use the RESET button, use a pen or pencil to press the button. When this is done, the SEHI initializes itself.

NOTE

All modules in a stacked configuration reset when the SEHI is reset.
