SEHI USER’S GUIDE
CLN
This red LED 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
1-24
•
EPIM-1: RCV LED
E1
•
EPIM-2: RCV LED
E2
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 1-12 on the SEHI-22 or ports 1-24 on the SEHI-24)
has a corresponding LNK LED.

USING THE RESET BUTTON
The SEHI incorporates a recessed Reset button. See Figure 5-1. This
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.
