Page 26: Rear Panel
Rear Panel Fans For cooling, the rear panel of the G8264 has four bays for hot‐swap fan modules. Four fan modules are required for redundancy. When four fan modules are used, if there is a failure of one of the fans, the switch reports the condition, the other fans continue to run, and the switch continues to operate normally. You can replace one failed hot‐swap fan module while the switch is operating. If a second fan fails, the switch reports the condition and shuts down to prevent overheating. Compatible fan options are listed in the Lenovo Networking Catalog. Fan operation and internal temperatures are monitored. If the air temperature exceeds a desired threshold, the environmental monitor displays warnings. Note: If a fan fails, the maximum operating temperature drops from +40°C (104°F) to +35°C (95°F). Fan LEDs If there is a failure of one or more fans, the front panel Fan LED flashes. Additional Fan LED indicators are located on the rear panel of the switch, on the individual fan modules.

Page 29 Two power supply modules are required for redundancy. Each power supply can be connected to a separate circuit to mitigate the risk of down‐time during a localized power failure. When used in a redundant configuration, the dual power supplies have a load‐sharing capability that enables each power supply to operate at approximately 50 percent of full load. Using redundant power can minimize the power disruption during a power supply failure and extend the expected lifetime of each power supply by operating normally in a conservative power mode. For proper airflow when operating the switch with only one power supply module, the empty power supply bay must be protected by a blank cover module. © Copyright Lenovo 2017 Chapter 2: Switch Components...
Page 30 There is no power switch on the G8264 power modules; the switch powers up when power is supplied through the power cord to one or both power supplies.

Page 36: Handling Static-Sensitive Devices
Handling Static-Sensitive Devices Attention: Static electricity can damage the switch and other electronic devices. To avoid damage, keep static‐sensitive devices in their static‐protective packages until you are ready to install them. To reduce the possibility of electrostatic discharge, observe the following precautions:  Limit your movement. Movement can cause static electricity to build up around you.  The use of a grounding system is recommended. For example, wear an electrostatic‐discharge wrist strap, if one is available.  Handle the device carefully, holding it by its edges or its frame.  Do not touch solder joints, pins, or exposed printed circuitry.  Do not leave the device where others can handle and damage it.  While the device is still in its static‐protective package, touch it to an unpainted metal part of any unpainted metal surface on a grounded rack component in the rack in which you are installing the device, for at least 2 seconds. This drains static electricity from the package and from your body.  Remove the device from its package and install it directly into the switch without setting it down.

This port uses RS‐232 serial communications. Use the console cable kit to connect the serial console port to a terminal or a computer running a terminal emulation program. © Copyright Lenovo 2017...
Page 76: Using The Management Port
Data bits = 8  Flow control = none Using the Management Port If the switch is connected to a network that employs DHCP, you can also access the switch CLI through the RJ‐45 management port. This port uses Ethernet communications and can be accessed using Telnet, SNMP, or a Web browser via the IP address provided by the network’s DHCP server. Logging In to the Switch When the switch starts, it performs initial self tests, and then prompts for the password. For example: Memory Test ........ Production Mode PPCBoot 0.0.0.10 (new flash) Memory Test (0x00) ......PASSED Lenovo G8264 Jan 6 00:11:36 2015: Password: At the prompt, type the switch password and press Enter. The default is admin. Note: If the switch has already started prior to your connection, you may need to press Enter to display the password prompt. Default Configuration Files The switch firmware contains default configuration files that are loaded at the factory. When the switch first initializes, the default configuration files are loaded into the active switch memory. The default settings allow the switch to perform basic functions with minimal effort by the system administrator. Custom configuration settings made by the administrator will override the default settings and can be saved so that they are retained if the switch is rebooted. However, if desired, you can revert the custom configuration settings to the original factory defaults. The original factory default configuration files are a permanent ...
Page 77: Configuring An Ip Interface For Remote Access
By default, DHCP is enabled on the management interfaces and BOOTP is enabled on interface 1. If there is no DHCP offer received, the switch uses the default management IP address (192.168.50.50/24). This address is overwritten when a DHCP/BOOTP address is received for that interface. If DHCP/BOOTP is enabled and there is no static address configured for DHCP/BOOTP, requests will continue to be sent. This feature does not change existing DHCP/BOOTP functionality. To configure an IP interface for remote management, complete the following steps. 1.Log on to the switch using the serial console port or management port on the G8264 front panel. 2.Enter IP interface mode. G8264> enable G8264# configure terminal G8264 (config)# interface ip 1 3.Configure an IP interface, subnet mask, and VLAN assignment, then enable the interface. G8264 (configipif)# ip address 10.10.10.2(example IP address) G8264 (configipif)# ip netmask 255.255.255.0 G8264 (configipif)# vlan 1 G8264 (configipif)# enable G8264 (configipif)# exit 4.Configure the default gateway. Enable the gateway. G8264 (config)# ip gateway 1 address 10.10.10.1(example gateway address) G8264 (config)# ip gateway 1 enable After you configure the IP address for your switch and you have an existing network connection, you can use the Telnet program from an external management station to access and control the switch. The management station and your switch must be on the same IP subnet. The switch CLI allows you to configure and control the switch over the network using the Telnet program. You can use the CLI to perform many basic network management functions. In addition, you can configure the switch for management using an SNMP‐based network management system or a web‐browser. For more information about using the CLI, see the Command Reference guide for your specific switch and firmware version. © Copyright Lenovo 2017 Chapter 5: Initializing the G8264...

Page 92: Important Notes
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. Some software might differ from its retail version (if available) and might not include user manuals or all program functionality. G8264 Installation Guide...
