Information LEDs 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. Lenovo ThinkSystem NE2552E Flex Switch: Installation Guide...

When you use the management‐module Web interface to update the switch configuration, the management‐module firmware saves the new configuration in internal nonvolatile memory. If the switch restarts, the CMM applies the saved configuration to the switch. For more information, see the Application Guide and the Command Reference for your specific switch and its installed firmware. For switch communication with a remote management station, such as an Lenovo Director management server, through the management‐module external Ethernet port, the switch internal‐network interface and the management‐module external interface must be on the same IP subnet. For specific details about configuring the switch and preparing for system installation, see the documentation listed in “Related Documentation” on page Notes: Unless otherwise stated, references to the CMM apply only to the Lenovo Flex System Chassis Management Module, which is the only type of management module that supports the switch. Throughout this document, the management‐module Web‐based user interface is also known as the Lenovo Flex System management‐module Web interface. Throughout this document, the user name is also known as the login name or user ID for logging on to interfaces or programs. The screens that are described or referenced in this document might differ slightly from the screens that are displayed by your system. Screen content varies according to the type of Lenovo Flex System chassis and the firmware versions and options that are installed. Lenovo ThinkSystem NE2552E Flex Switch: Installation Guide...
Enabled The switch can be managed through the CMM or a compute node. No traffic is allowed on internal or external switch ports. Enabled Enabled The switch can be manage through the CMM, a compute node, or a management station that is connected through the swtich. Data traffic is allowed on internal and external switch ports. To enable management through data ports, complete the following steps: 1. Log on to the CMM CLI as described in the CMM documentation. If necessary, obtain the IP address of the CMM from your system administrator. 2. Set the environment to the bay where you installed the switch: system> env -T system:switch[1] 3. Execute the ifconfig command to enable data ports and external management: ifconfig -ep enabled -em enabled You can now manage the switch using its data ports or external management port. Note: “External management” refers to means other than by the CMM. To externally manage the switch, additional IP interfaces must be configured. For more information see the Application Guide for your specific switch and its installed firmware. Lenovo ThinkSystem NE2552E Flex Switch: Installation Guide...
To log in to the switch, complete the following steps: 1. Connect one end of the specifically designed serial cable that comes with your device into the RS‐232 port and connect the other end to the management station. For additional information, see “Connecting the Serial Console Cable” on page 2. On the management station, open a console window and make sure that the serial port is configured with the following settings: 9600 baud 8 data bits No parity 1 stop bit No flow control 3. When prompted, enter your user name and password. When logging in to a switch for the first time, the default switch administrator user name is USERID, and the default password is PASSW0RD (where the sixth character is the number zero, not the letter O). The User ID and password fields are case‐sensitive. For security purposes, you will be prompted to change the administrator password after the first successful login. Otherwise, if you have an assigned user account, use your assigned user name and password. The serial port is compatible with the standard 16550 Universal Asynchronous Receiver/Transmitter (UART) protocol. The RS‐232 serial port is enabled by default. Lenovo ThinkSystem NE2552E Flex Switch: Installation Guide...
Note: Updating the firmware involves rebooting the switch. If you have made any configuration changes you wish to persist beyond the upgrade process, you must type the copy running-config startup-config command. This command stores the current switch configuration and all changes to nonvolatile memory. To transfer the switch firmware image files from the FTP, TFTP or SFTP file server to the switch, you can establish a Secure Shell (SSH) v2 or Telnet session through the CMM. Ping the file server to make sure that you have a connection. The session performs optimally if all three network entities (file server, CMM, and switch IP addresses) are on the same subnet. Otherwise, you must use a router and configure a gateway address on the switch. Use the management‐module interface to configure the IP addresses of the CMM external interface (eth0) and the switch so that they are both on the same subnet as the file server. Examples of IP addresses and masks are described in the following table. Network entity IP address Mask FTP, TFTP or SFTP file 192.168.2.178 255.255.255.0 server CMM (eth0) 192.168.2.237 255.255.255.0 Switch‐module current 192.168.2.51 255.255.255.0 IP configuration (IF 128) Note: With this configuration, you can ping the switch from the file server.

Running POST To ensure that it is fully operational, the switch processes a series of tests during power‐up or a restart (Power‐On Self‐Test, or POST). These tests may take up to two minutes to complete. The Lenovo Flex System Chassis Management Module (CMM) reads the test results and displays them for you. During normal operation, these tests are completed without error, and the green switch Power LED is lit. However, if the switch fails POST, the yellow Error LED on the switch and the system‐error LED on the chassis are lit. An event is stored in the event log in the system status panel of the CMM. The specific failure is displayed on the system status I/O module panel of the CMM.

Important Notes Processor speed indicates the internal clock speed of the microprocessor; other factors also affect application performance. CD or DVD drive speed is the variable read rate. Actual speeds vary and are often less than the possible maximum. When referring to processor storage, real and virtual storage, or channel volume, KB stands for 1 024 bytes, MB stands for 1 048 576 bytes, and GB stands for 1 073 741 824 bytes. When referring to hard disk drive capacity or communications volume, MB stands for 1 000 000 bytes, and GB stands for 1 000 000 000 bytes. Total user‐accessible capacity can vary depending on operating environments. Maximum internal hard disk drive capacities assume the replacement of any standard hard disk drives and population of all hard‐disk‐drive bays with the largest currently supported drives that are available from Lenovo. Maximum memory might require replacement of the standard memory with an optional memory module. Each solid‐state memory cell has an intrinsic, finite number of write cycles that the cell can incur. Therefore, a solid‐state device has a maximum number of write cycles that it can be subjected to, expressed as total bytes written (TBW). A device that has exceeded this limit might fail to respond to system‐generated commands or might be incapable of being written to. Lenovo is not responsible for replacement of a device that has exceeded its maximum guaranteed number of program/erase cycles, as documented in the Official Published Specifications for the device. Lenovo makes no representations or warranties with respect to non‐Lenovo products. Support (if any) for the non‐Lenovo products is provided by the third party, not Lenovo.
