Using Lanview - Cabletron Systems IRM-2 Installation Manual

TESTING AND LANVIEW
6. Verify that this test passes. At least 100 packets should be sent and
received with no errors. Packets will be sent from this LAN-MD to the
other LAN-MD, acting as the Server, then echoed back.
When the IRM-2 has successfully completed these tests, the module is
ready for normal operation. If any failures were noted, please contact
Cabletron Systems' Technical Support.

USING LANVIEW

The IRM-2 uses Cabletron Systems' built-in visual diagnostic and status
monitoring system called LANVIEW (Fig. 4-1). With LANVIEW,
network troubleshooting personnel can quickly scan LANVIEW's LEDs
to observe network status, or diagnose network problems.
ERROR (ERR) LED
When this red LED is lit, the CPU has detected a problem with the
IRM-2.
POWER (PWR) LED
When this green LED is lit, the IRM-2 is receiving power from the
MMAC.
RECEIVE (RCV) LED
When this yellow LED is flashing, the IRM-2 is repeating a data packet
received from one of the segments connected to the MMAC.
TRANSMIT (XMT) LED
When this green LED is flashing, the IRM-2 is transmitting a data packet
out to all segments connected to the MMAC.
COLLISION PRESENT (CLN) LED
When this red LED is flashing, this indicates that a collision is being
detected on one of the segments connected to the MMAC.
PORT OK (POK) LED
This green LED is lit to indicate that the Network Interface Chip
associated with the IRM-2's internal repeater port has passed an internal
Loop Back Test and is ready for transmission.
