Connectors and Indicators
1-21
General Information
Each power supply has a separate CTP card connection to allow for
independent AC power sources. The power supplies are input-rated
at 100 to 230 volts alternating current (VAC).
Connectors and Indicators
Connectors and indicators include the:
• Initial machine load (IML) button.
• 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 1-6 on page 1-19) 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 1-6 on page 1-19) 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.
