CLN
This red LED indicates that a collision has occurred on one of the
ports.
RCV
When this yellow 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 twisted pair segment and the 10BASE-T device at the
other end of the segment. LNK LEDs will remain on as long as a link
is maintained. Each SEHI Network Port (ports 1-24) 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
non-volatile random access memory where the SEHI stores network
management parameters.
To use the Reset button, use a pen or pencil to press the button in.
When this is done, the SEHI initializes itself.
