1 Introduction The Consolidated Client Infrastructure (CCI) solution uses a 3U (5.25-inch) HP BladeSystem PC Blade Enclosure supporting 20 HP Blade PCs and redundant, hot-plug power and cooling. The HP BladeSystem PC Blade enclosure with 20 HP blade PCs contains 40 10/100 Mbps network adapters (NIC). Since the CCI solution packages many HP Blade PCs in a small space, the number of network cables within this space can quickly become overwhelming.
Switch Configuration You can independently disable or enable the switch ports. Auto-MDI/MDIX with auto negotiation of speed and duplex is supported.
HP PC Blade Switch Interconnect Tray The PC Blade Switch has the following port configuration.
External Ports The HP PC Blade Switch includes eight external ports, four 10/100/1000T Mbps Ethernet "uplink" ports with RJ-45 connectors, typically used to connect the switch to the network infrastructure, and four Small Form-factor Pluggable (SFP) GBIC ports which can be used for Gigabit Fiber connectivity. These ports are shared "combo" ports, whereas only one media type can be used at a time. Combo ports are single ports with two physical connections, RJ-45 copper or SFP.
Command Line Interface (CLI) The CLI provides many more configuration options than the browser-based interface. There are three methods of accessing these interfaces: ● Locally with the RS-232 console port on the switch tray by way of logging into the Integrated Administrator and connecting to the PC Blade Switch through the internal serial link. ● Remote virtual serial access to the switch through the Integrated Administrator by way of a builtin account.
External LEDs are provided for enclosure and switch status and for link and speed on each Ethernet uplink (see HP PC Blade Switch tray external panel LEDs). An emergency enclosure shut-down feature is included in case of critical system temperature caused by the switch or other enclosure component.
Switch Serviceability The switch provides many additional serviceability and diagnostic features including: ● Port mirroring with the ability to mirror desired type of frames (egress, ingress, or both). ● Power-on self test (POST) at boot for hardware verification. ● Monitoring screens using the user interfaces for port utilization, data packets received/transmitted, error packets, packet size, trunk utilization, SNMP data, etc.
This period is considered too long for many applications. The delay is needed to allow enough time to detect possible loops, allowing time for status changes to propagate and be acted upon by all relevant devices. In this switch, when network topology allows, faster convergence may be possible. The Rapid Spanning Tree Protocol (RSTP) is designed to detect and make use of network topologies that allow a faster convergence of the spanning tree, without creating forwarding loops.
an “Aggregated Link” may be of different media types (UTP/Fiber, or different fiber types), provided they are of the same speed and duplex. Aggregated Links may be set up manually, or automatically by enabling LACP (Link Aggregation Control Protocol) on the relevant links. An Aggregated Link is treated by the system as a single logical port, in the same manner as any other port in the system.
system supports eight queues per port. The system services the queues (takes frames out of a queue for transmission) according to the current queue scheduling settings, as defined by the user. These settings determine which queue is handled and how many frames from that queue will be handled before any other queue is managed. While the system facilities providing Access Control and CoS/QoS are given, there are several ways to configure the system to provide the desired effect.
The switch and the IA have separate and independent IP addresses. The 20 PC blades, switch, and the IA altogether comprise a single chassis. A 42U rack may contain up to 14 chassis.
2 First Time Installation After completing all external connections, connect a terminal (with terminal emulation software) to the Integrated Administrator 's external DB-9 RS232 serial port. To configure the Integrated Administrator, please refer to the Integrated Administrator documentation. Ensure that the terminal emulation software is configured as follows: 1. Integrated Administrator external serial port: 9600 baud. 2. Set the data format to 8 data bits, 1 stop bit, and no parity. 3.
Installation Procedure The order of installation and configuration procedures is illustrated in the following figure. For the initial configuration, the standard device configuration is performed. Performing other functions is described later in this section.
Booting the PC Blade Switch The PC Blade Switch will power on automatically when one or more of the enclosure power supplies are plugged in. The assumed bootup information is as follows: ● The PC Blade Switch is delivered with a default configuration that differs from a typical distribution or edge switch. ● The default user name for the PC Blade Switch Web Management Interface is admin. Note: if connecting to the switch via the Integrated Administrator, no user name is required.
FRU Validation Test...............................PASS BOOT Software Version x.x.x.xx Built 22-Jan-xxxx 15:09:28 I-Cache x KB. D-Cache x KB. Cache Enabled. Autoboot in 2 seconds -press RETURN or Esc. to abort and enter prom. Preparing to decompress... The boot process runs for approximately 60 seconds. The auto-boot message displayed at the end of POST (see the last lines) indicates that no problems were encountered during boot. During boot, the Startup menu can be used to run special procedures.
The initial configuration consists of the following: ● Setting the user name TBD, password as TBD with the highest privilege level of 15 ● Configuring the static IP address and the default gateway ● Configuring the SNMP read/write community strings Before applying the initial configuration procedure, please obtain the following information from the network administrator: ● The IP address to be assigned to a VLAN through which the device is managed.
console(config)# ip default-gateway 192.168.1.1 console(config)# exit Verifying the IP and Default Gateway Addresses Ensure that the IP address and the default gateway were properly assigned by executing the command show ip interface and examining its output: Console# show ip interface Gateway IP Address Activity status --------------------- --------------- 192.168.1.1 active IP address Interface Type ------------ ---------- ------ 192.168.1.
station IP address and community (community name and access rights). The SNMP management access to the switch is disabled if no community strings exist. NOTE: The switch is delivered with the PUBLIC, read-only, community string configured with no password. No write community strings are configured by default. You can configure the community-string, community-access, and IP address through the switch CLI during the initial configuration procedure.
To configure SNMP station IP address and community string(s), perform the following: 1. At the console prompt, type Enable. The prompt is displayed as #. 2. Type configure and press Enter. 3. In configuration mode, type the SNMP configuration command with the parameters including community name (private), community access right (read and write) and IP address, as shown in the following example: console> enable console# configure config(config)# snmp-server community private rw 192.168.1.
This completes the initial configuration of the PC Blade Switch from the CLI. The configured parameters enable further configuration from any remote location.
Configuring an Initial Console Password To configure an initial console password, type the following commands: console> enable console# configure console(config)# aaa authentication login default line console(config)# aaa authentication enable default line console(config)# line console console(config-line)# login authentication default console(config-line)# enable authentication default console(config-line)# password george When initially logging onto the PC Blade Switch through a console session, type geor
console(config-line)# enable authentication default console(config-line)# password jones console(config-line)# exit console(config)# aaa authentication login default line console(config)# aaa authentication enable default line NOTE: Use one of the following commands to generate either a DSA or RSA key pair. For more information on key generation, please see the CLI guide. console(config)# crypto key generate dsa console(config)# exit Since this method uses the Default logon, a user name is not required.
NOTE: SSL 2.0 or higher must be enabled in the client browser for the HTTPS session to work properly. HTTP and HTTPS services require level 15 access and connect directly to the configuration level access. Software Download from a TFTP Server This section contains instructions for downloading switch software (system and boot images) from a TFTP server. You must configure the TFTP server before beginning to download the software.
When the new image is downloaded, it is saved in the area allocated for the "not active" system image (image-2, as given in the example).
