Statement 25 CAUTION: This product contains a Class 1M laser. Do not view directly with optical instruments. UL Regulatory Information This device is for use only with listed Lenovo Flex System Enterprise Chassis. EN4093R 10 Gb Scalable Switch User’s Guide...
Chapter 1. The EN4093R 10 Gb Scalable Switch Introduction ® This User’s Guide provides information about the Lenovo Flex System™ Fabric EN4093R 10 Gb Scalable Switch (referred to as EN4093R or “switch” throughout this document). Figure 1. The EN4093R SFP+ module ports...
The EN4093R provides flexible, reliable, and high-performance features that meet the demands of today's highly virtualized environments. The EN4093R provides pay-as-you-grow scalability. With optional licensing, you can easily and cost-effectively expand the number of available ports. Depending on the installed licenses, the scalable switch can provide up to sixty-four 10 Gigabit Ethernet (GbE) ports.
The console output described or referenced in this document might differ slightly from that displayed by your system. Output varies according to the type of Lenovo chassis and the firmware versions and options that are installed. Notices and Statements in this Document The caution and danger statements in this document are also in the multilingual Safety Information document, which is on the included Documentation CD.
Command Reference for your specific switch and its installed firmware. See the documentation that came with your Lenovo chassis for information about the environmental conditions and specifications that are supported by the system. EN4093R 10 Gb Scalable Switch User’s Guide...
A Lenovo Flex System network adapter must be installed in each compute node with which you want to communicate. To enable the switch to communicate with a compute node, at least one switch must be installed in the Lenovo Flex System chassis. For details about network adapter installation, configuration, and use, see the documentation that comes with the Lenovo Flex System network adapter.
Note: • I/O bays 1 and 2 support any standard Lenovo Flex System switch or pass-thru module. When you install an I/O network adapter in the left-most fabric connector on the compute node, these I/O bays support any switch with the same type of network interface that is used by the corresponding network adapter.
To help ensure proper cooling, performance, and system reliability, make sure that the following requirements are met: • Each of the bays on the rear of the Lenovo Flex System chassis contains either a module or a filler module. •...
Installing the EN4093R Note: The following illustration shows how to install the switch in a Lenovo Flex System chassis. The appearance of your Lenovo Flex System chassis might be different; see the documentation for your Lenovo Flex System chassis for additional information.
Removing or Replacing the Switch Note: The following illustration shows how to remove and replace the switch from the Lenovo Flex System chassis. The appearance of your Lenovo Flex System chassis might be different; see the documentation for your Lenovo Flex System chassis for additional information.
Disconnecting the Serial Console Cable To disconnect the serial console cable, grasp the connector and gently pull the cable from the switch. The RJ-45 Management Port Connecting RJ-45 Cables RJ-45 cables can be connected to the to external management port, and also to SFP+ ports that have legacy 1000BASE-T SFP transceiver modules.
Use minimal pressure when you insert the module into the switch port. Forcing the module into the port can cause damage to the module or port. • You can insert or remove the module while the Lenovo Flex System chassis is turned on. •...
2. If you have not already done so, touch the static-protective package that contains the SFP+ module to an unpainted metal surface of the Lenovo Flex System chassis or an unpainted metal surface on any other grounded rack component in the rack in which you are installing the switch for at least 2 seconds.
Removing an SFP+ Module To remove the SFP+ module, complete the following steps. 1. Read the safety information that begins on page 5 “Installation Guidelines” on page 2. Read the information in “Handling Transceiver Modules” on page 3. Remove the fiber optic cable from the module that you want to replace. For more information about removing the cable, see “Disconnecting a Fiber Optic Cable”...
Removing a QSFP+ Module To remove the QSFP+ module from the switch port, complete the following steps. 1. Read the safety information that begins on page 5 “Installation Guidelines” on page 2. Read the information in “Handling Transceiver Modules” on page 3.
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.
When lit, this LED indicates a POST failure or critical alert. As a result, the system-error LED on the Lenovo Flex System chassis is also lit. When this LED is off and the green Power LED is lit, it indicates that the switch is working correctly.
192.168.70.120, 192.168.70.121, 192.168.70.122, or 192.168.70.123 depending on the bay where the switch is installed. • If you change the IP address of the switch and restart the Lenovo Flex System chassis, the switch maintains this new IP address as its default value. •...
“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. •...
Enabling Management Through Data Ports To access and manage the switch through external interfaces, you must enable the data (non-management) ports and the ability to manage the switch through them. Use the information in the following table to configure your ports. Data Ports External Mgmt Description...
Accessing the Switch Through the Serial-Port Interface The serial port provides basic communication RS-232 serial-data transfer through a terminal emulation program (such as Hyperterminal). Because messages from the power-on self-test (POST) and all initialization information are transmitted through the serial port, you can use the serial port to log in to the switch and access and configure the internal switching firmware.
Determining the Level of Switch Firmware After you install the switch in the Lenovo Flex System chassis, make sure that the latest firmware is installed on the switch. To determine the level of the firmware that is installed, complete the following steps.
Resetting and Restarting the Switch To activate the new image or images, you must reset the switch. To reset the switch, 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.
Installing Feature Licenses Once Features on Demand activation key files have been acquired, they must be installed on the switch. The example below illustrates use of the switch CLI, but other interfaces may also be used, such as the Browser Based Interface (BBI), or Simple Network Management Protocol (SNMP).
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.
The following table describes the basic critical and noncritical failures. This abbreviated list is representative; it is not an exhaustive list. An error code is associated with each failure. Error codes are displayed on the CMM Switch Information window. Be sure to note the applicable error code and corresponding failure.
