Note: If a fan module fails, the maximum operating temperature drops from +40Cto +35C (104F to 95F).

The Service ( ! ) LED is lit if there is a failure of one or more fan modules. Thefailed fan module LED (rear panel) flashes to indicate a failure.AC power supplyThe switch has two hot-swap redundant 450 W AC power supplies. Each internalpower supply has an individual IEC 320 power connector on the rear panel. Thepower cord attaches to a universal grounded AC power source. You can replace ahot-swap power supply module without powering off the switch or disrupting switchfunctions.

DANGER

An electrical outlet that is not correctly wired could place hazardousvoltage on the metal parts of the system or the devices that attach to thesystem. It is the responsibility of the customer to ensure that the outlet iscorrectly wired and grounded to prevent an electrical shock. (D004)

Each power supply can be connected to a separate AC circuit to mitigate the risk ofdown time during a power failure. When used in a redundant configuration, the dualpower supplies have a load-sharing capability that enables each power supply tooperate at approximately 50 percent of full load. Using redundant power canminimize the power disruption during a power supply failure and extend theexpected lifetime of each power supply by operating normally in a conservativepower mode.

There is no power switch on the G8264; the switch unit powers up when power issupplied through the power cords.

The Power Supply LED indicates the status of the power supplies. The LED flasheswhen only one power cord is connected, and is steady when both power cords areconnected.

Switch portsThe RackSwitch ports and port options are described in the following sections.

SFP+ ports





(C026)


Forty-eight 10 GbE Small Form-factor Pluggable Plus (SFP+) ports are located onthe front panel. These ports accept supported optical or copper SFP or SFP+transceivers, or direct attach cables (DACs). Transceivers must be purchasedseparately.

For the available transceivers and direct attach cables (DACs) for the switch, seehttps://www-01.ibm.com/products/hardware/configurator/americas/bhui/launchNI.wss.

QSFP+ portsFour 40 GbE Quad Small Form-factor Pluggable Plus (QSFP+) ports are located onthe front panel. These ports accept supported optical QSFP+ transceivers or directattach cables (DACs). The supported transceivers interoperate with any40GBASE-SR4 compliant device, and support distances up to 100 meters on OM3fiber. Transceivers must be purchased separately.

QSFP+ ports allow you to make one 40 GbE connection, or four 10 GbEconnections, using a breakout cable, as follows:v QSFP+ optical transceiver with MTP-to-4 LC (SFP+) fiber breakout cable. This

option supports only 10GBASE-SR SFP+ transceivers. The 40GBASE-SR4specification (802.3ba-2010) indicates a higher optical power level than standard10GBASE-SR. SFP+ SR transceivers can handle the higher optical power levels.

v QSFP+ to four 10 GbE SFP+ breakout DAC. The SFP+ connectors on supportedbreakout DACs are labelled A, B, C, and D, which correspond to the first,second, third, and fourth ports in the port range.

Handling static-sensitive devicesAttention: Static electricity can damage the switch and other electronic devices.To avoid damage, keep static-sensitive devices in their static-protective packagesuntil you are ready to install them.

To reduce the possibility of electrostatic discharge, observe the followingprecautions:v Limit your movement. Movement can cause static electricity to build up around

you.v The use of a grounding system is recommended. For example, wear an

electrostatic-discharge wrist strap, if one is available.v Handle the device carefully, holding it by its edges or its frame.v Do not touch solder joints, pins, or exposed printed circuitry.v Do not leave the device where others can handle and damage it.v 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 therack in which you are installing the device, for at least 2 seconds. This drainsstatic electricity from the package and from your body.

v Remove the device from its package and install it directly into the switch withoutsetting it down. If it is necessary to set down the device, put it back into itsstatic-protective package. Do not place the device on a switch cover or on ametal surface.

v Take additional care when you handle devices during cold weather. Heatingreduces indoor humidity and increases static electricity.

Password:

At the Password prompt, enter the switch password, and press Enter. The defaultpassword is admin.

Default configurationThe switch software contains default factory-loaded configuration files. The defaultconfiguration is part of the software; it cannot be deleted or changed. The defaultsettings allow the switch to perform basic functions with minimal effort by thesystem administrator. DHCP is enabled by default on the management interfacesand BOOTP is enabled by default on interface 1. If there is no DHCP offer received,the device uses the default Mgmt _IP address (192.168.50.50/24). This address isoverwritten when a DHCP/BOOTP address is received for that interface. IfDHCP/BOOTP is enabled and there is no static address configured forDHCP/BOOTP requests will continue to be sent. This feature does not changeexisting DHCP/BOOTP functionality. See the following initial configuration example:


RS G8264# show inter ipInterface information:1: IP4 192.168.49.50 255.255.255.0 192.168.49.255, vlan 1, up128: IP4 192.168.50.50 255.255.255.0 192.168.50.255, vlan 4095, up! interface ip 1! addr ! enable!! interface ip 128! addr ! enable

RS G8264(config)# system dhcp?

mgt dhcp on mgt portRS G8264(config)# system dhcp mgt

Warning: Enabling dhcp will overwrite IP interface 128 and IP gateway 4 configurations.RS G8264# show inter ip

Interface information:1: IP4 192.168.49.50 255.255.255.0 192.168.49.255, vlan 1, up128: IP4 192.168.50.50 255.255.255.0 192.168.50.255, vlan 4095, up

Configuring an IP interfaceTo manage the switch using Telnet, SNMP, or a web browser, you must configurean IP interface. Configure the following IP parameters:v IP addressv Subnet maskv Gateway address1. Log on to the switch.2. Enter IP interface mode.

RS G8264> enableRS G8264# configure terminalRS G8264 (config)# interface ip 1

3. Configure an IP interface, subnet mask, and VLAN assignment. Enable theinterface.RS G8264 (config-ip-if)# ip address 10.10.10.2 (example IP address)RS G8264 (config-ip-if)# ip netmask 255.255.255.0RS G8264 (config-ip-if)# vlan 1RS G8264 (config-ip-if)# enableRS G8264 (config-ip-if)# exit

4. Configure the default gateway. Enable the gateway.RS G8264 (config)# ip gateway 1 address 10.10.10.1 (example gateway address)RS G8264 (config)# ip gateway 1 enable

After you configure the IP address for your switch and you have an existingnetwork connection, you can use the Telnet program from an externalmanagement station to access and control the switch. The management stationand your switch must be on the same IP subnet.The G8264 Rackswitch supports a command-line interface (CLI) that you canuse to configure and control the switch over the network using the Telnetprogram. You can use the CLI to perform many basic network management

Chapter 4. Initializing the RackSwitch 51

functions. In addition, you can configure the switch for management by using anSNMP-based network management system or a web browser.For more information about using the CLI, see the Command Reference for theswitch.

Updating firmwareIf firmware updates are available, you can download them fromhttp://www.ibm.com/supportportal/. The switch might have features that are notdescribed in the documentation that comes with the switch, and the documentationmight be updated occasionally to include information about those features, ortechnical updates might be available to provide additional information that is notincluded in the switch documentation.

Configuration settings are lost during a firmware update. Before updating thefirmware, save a copy of the configuration on a separate device. In the event of afailed update, the saved configuration can be restored. For more information aboutthe configuration file, see the Application Guide and Command Reference for theswitch.
