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 replace an existing switch without having to power down the serv er blades or the server blade enclosure • Pre-configured for immedia te use with the HP[...]

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. • Allows secure browser access (H TTPS) to management functions Switch redundancy In a dual switch configuration, the switches offer several redundancy and failove[...]

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 Insight Manager automatic discovery and identification • POST built into the switch boot process • Switch port mirroring • Switch LED panel disp[...]

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. Redundant Ethernet signals from each blade server are routed through[...]

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. NOTE: STP 16 is reserved for future functionality. The switch al[...]

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. This information displays on the management interfaces and is used to record the date and tim[...]

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. • The accounting attributes of protocol,[...]

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. Redundant images in f[...]

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. These ports (17 and 18) are disabl ed by default. [...]

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. 3. From a computer connected to the same network, use the IP address to[...]
