Introduction 7 • Fully supported on the HP c-Clas s BladeSystem serv er blade enclosure and infrastructure compatible with any combination of HP c-Class BladeSystem server blades • Ability to repl.
Introduction 8 • Port Fast Forwarding that allows a port that par ticipates in Spanning Tree to bypass the Listening and Learning states and enter directly into the Forwarding state.
Introduction 9 • Any switch port can be used to perform switch management and PXE. Diagnostic tools The hardware, software, and firmware diagno stic tools that are available include: • HP Systems .
Introduction 10 Redundant paths to server bays In a dual switch configuration, redundant Ethernet si gnals from each blade server are routed through the enclosure backplane to separate switches within th e enclosure. This configurati on provides redundant paths to each server bay.
Introduction 11 In addition, the switch provides a spanning tree doma in per VLAN. The switch is compatible with Cisco® PVST+ and Cisco PVST, when the other device is co nfigured as untagged or conf igured to use 802.1q tagging. Sixteen spanning tree domains are supported per switch.
Introduction 12 configurable from the browser-based interface, but because the connection is based on an IP address for these interfaces, users will have to recon n ect with the newly assigned IP address. NTP The switch maintains the current date and time.
Introduction 13 • Only standard ASCII inbound login authentication . PAP, CHAP, or ARAP login methods are not supported. One-time password authen tication is also not supported. • Authorization privilege lev els of only 0, 3, and 6. These map to management levels of user, oper, and admin, respectively.
Introduction 14 through a procedure called auto-negotiation. Auto-neg otiation involves probing the capability of the network using low-level signaling tec hniques to select compatible Ethe rnet speeds. Aut o-negotiation was originally developed to make the migration from trad itional Ethernet to Fast Ethernet products easier.

Installing the switch 17 • SNMP settings • User name and password settings • Default access to various management interfaces • NTP settings IMPORTANT: See "Runtime switching soft ware default settings (on page 28 )" for a complete list of default configuration settings.
Installing the switch 18 User account Description an d tasks performed Password Operator The operator manages all functions of the switch. The operator can reset ports or the entire switch. By default, the operator account is disabled and has no password.
Installing the switch 19 Installing the switch CAUTION: Do not cable the switch until after configuration. IMPORTANT: Make sure that the server NIC configuration matches the s witch bay selected. NOTE: When installing two switches, there are tw o switch interconnect ports between adjacent I/O bays.
Installing the switch 20 To access the switch remotely: 1. Assign an IP address. By default, the switch is set up to obtain its IP address from a BOOTP server existing on the attached network. 2. From the BOOTP server, use the switch MAC address to obtain the switch IP address.
Installing the switch 21 See "SNMP MIBs support (on page 42 )" for more information on the SNMP agents. This section also describes how to use the MIB s to configure and moni tor the switch using a generic SNMP manager, such as HP OpenView Network Node Manager or HP Syste ms Insight Manager.

Troubleshooting 50 • The switch IP address is no t configured or correct. • From the serial console interface, be sure that the switch IP address is configured and valid on the network. • Use the correct IP address to establis h the SSH connection with the switch.
Troubleshooting 51 • The management network address/mask (if used ) does not contain the IP address of the management station. From the serial console in terface, be sure that the management network address/mask contains the IP address of the management station.
Troubleshooting 52 • Be sure that the TFTP server exists on the sa me network or VLAN as that of the switc h. • Be sure that the TFTP server can be pi nged from the switch and vice versa. • Be sure that the IP address of the TFTP server is correct.
