EN4093R 10 Gb Scalable Switch User's Guide
The switch-module information panel contains the following components.
• LEDs that display the following information:
– The status of the switch (Power, Locator, and Error)
– The status of the external connections to the switch
For further details about LEDs, see
• Fourteen 10 GbE SFP+ port connectors for SFP+ modules or DACs. These
connectors are identified as ports EXT1 through EXT14 in the I/O-module
configuration menus and are labeled 1 through 14 (from top to bottom) on the
switch.
• Two 40 GbE QSFP+ port connectors that can be used as eight 10GbE SFP+
ports. These connectors are identified as ports EXT15 and EXT19 (or EXT15
through EXT18, and EXT19 through EXT22, depending on configuration) in the
I/O-module configuration menus, and are labeled 15 through 22 (from top to
bottom) on the switch.
• One 9600 baud RS-232 serial port connector for switch console (management)
purposes. This connector is located near the bottom of the switch panel, just
above the management (Mgmt) port. Do not attach any devices to this connector
other than the serial access cable option specified for the switch.
• One 1 Gb Ethernet RJ-45 port connector for switch management purposes. Do
not attach any devices to this connector other than when using an industry
standard CAT5 cable. This connector is identified as port EXTM in the
I/O-module configuration menus and is labeled Mgmt on the switch.
For additional details, see
LEDs" on page 31.
The front panel of the switch has LEDs for system and port status. The Power,
Locator, and Error LEDs indicate the switch status. The Link (LINK) and Activity
(TX/RX) LEDs indicate the status of the external ports.
Notes:
• A yellow LED on the Lenovo Flex System chassis is lit when a system error or
event has occurred. To identify the error or event, check the Lenovo Flex System
management-module event log or the switch system log.
• During POST, the switch Power LED continuously flashes. Additionally, all of the
switch status LEDs and the licensed Port LEDs are lit as a visual indication they
are working. Once POST has successfully completed, the switch Power LED
remains on and the switch Error LED is off.
Any errors that are detected during POST are written to the system log. For
information about the command to read the system log, see the Command
Reference for the switch.
When POST errors are written to the system log, these errors are also written to the
Lenovo Flex System management-module event log. If a hardware error, such as a
current fault occurs, the CMM displays it. If a firmware error occurs, the CMM
displays the Module did not complete POST message and a post error code that
indicates the test that was running when the error was detected.
Note: You can also use the CMM to make sure that the switch is operating
correctly. For more information, see the CMM documentation.
