SAN32M1 Fabric Switch Installation and Service Manual 22
• Ethernet LAN connector.
• Green power (PWR) and amber system error (ERR) LEDs.
• Green and amber status LEDs associated with FRUs.
• RS-232 maintenance port.
Initial Machine load button
When the IML button ( Figure 6 on page 19) is pressed and held for
three seconds, the switch performs an IML that takes approximately
30 seconds and resets the:
• Microprocessor and functional logic for the CTP card and loads
firmware from FLASH memory.
• Ethernet LAN interface, causing the connection to the
management server to drop momentarily until the connection
automatically recovers.
• Ports, causing all Fibre Channel connections to drop momentarily
until the connections automatically recover.
An IML should only be performed if a CTP card failure is indicated.
Do not IML the switch unless directed to do so by a procedural step
in this manual,or the next level of support. As a precaution, the IML
button is flush mounted to protect against accidental activation.
Ethernet LAN connector
The front panel provides a 10/100 megabit per second (Mbps) RJ-45
twisted-pair connector (
Figure 6 on page 19) that attaches to an
Ethernet LAN to provide communication with the management
server or an SNMP management workstation. Two green LEDs are
associated with the LAN connector. When illuminated, the left LED
indicates LAN operation at 10 Mbps, and the right LED indicates
LAN operation at 100 Mbps.
Power and system error LEDs
The PWR LED ( Figure 6 on page 19) illuminates when the switch is
connected to facility AC power and powered on. If the LED
extinguishes, a facility power source, power cord, or power
distribution failure is indicated.
The ERR LED ( Figure 6 on page 19) illuminates when the switch
detects an event requiring immediate operator attention, such as a
