1. Introduction Currently Dell’s PowerEdge servers include a range of system management hardware and software support components functions including Dell OpenManage Server Administrator (OMSA), Dell OpenManage IT Assistant (ITA), the Dell Remote Access Controller (DRAC), and the baseboard management controller (BMC).
PAGE 3
- OpenManage’s IT Assistant provides support for network monitoring and can discover servers attached to IP networks. IT Assistant’s console provides views of all managed systems, including health and alert status. Working in conjunction with Server Administrator, IT Assistant provides robust discovery, inventory, and monitoring of Dell servers. It can also monitor clients and network hardware, in addition to servers.

o o Select Console Redirection and press Enter. For Console Redirection, set Serial Port 1 (or just Serial Port if only one is present). For Failsafe Baud Rate, set 19200. For Remote Terminal Type, set VT100/VT220. For Redirection after boot, set Enabled Press Escape, then Escape again to save changes and exit Configuring the BMC When the BMC banner is displayed, press Ctrl-E. Select IPMI Over LAN and set it to ON Select IPMI LAN Channel and press Enter.

Enable your operating system's console on the PowerEdge In order to access your operating system using SOL, you must tell it to run a console on the serial port when the OS starts. For Windows 2003 Server: Use the bootcfg command to start Emergency Administration Services (EMS) on the serial port From a command prompt (Start -> Run -> cmd.

Ensure your Opengear unit is running firmware version 2.2.3 or later. The latest firmware is available from ftp.opengear.com From the Serial & Network menu, select Network Hosts. Click Add Host. Enter the IP Address of the BMC as detailed above in the Configuring the BMC step (i.e. in this example we used 192.168.0.200) Remove any Permitted Services you do not require, select the UDP radio button and enter Port 623. Click Add.

Also ensure there are no conflicting services running on TCP port 623. When I select Activate Console Redirection from the SOL Proxy menu, the connection times out. Ensure the Opengear SSH gateway is configured to allow SOL for the gateway user you are using with SDTConnector (e.g. delladmin), as per the section Configuring the Opengear SSH gateway to permit SOL.

From the Serial & Network menu, select Network Hosts. Click Add Host. Enter the IP Address of the DRAC as detailed above in the Configuring the DRAC step (i.e. in this example we used 192.168.0.120) Remove any Permitted Services you do not require, but do not remove HTTPS (TCP port 443) and VNC (TCP port 5900). Scroll to the bottom of the page and click Apply From the Serial & Network menu, select Users & Groups.

5. OpenManage Server Administrator Dell OpenManage Server Administrator is included with all PowerEdge servers. It is a software package that provides server monitoring and control functions similar to the some of the functions DRAC, however it runs as a service under the server operating system. So it an in-band software management tool, unlike the BMC and DRAC tools, and is not useful for access when the operating system has crashed or become unavailable.

Remove any Permitted Services you do not require, select the TCP button and enter Port 1311 and click Add. Enter Port 3668 and click Add. Scroll to the bottom of the page and click Apply From the Serial & Network menu, select Users & Groups. If you have not already, click Add User, otherwise Edit the user and skip to the next paragraph. Enter a Username for the new user, e.g. delladmin. Enter and confirm a gateway Password for this user.

Installing IT Assistant on the PowerEdge To install IT Assistant on the PowerEdge server: Insert the OpenManage Systems Management CD that was shipped with your PowerEdge. If you are running Windows, follow the prompts until you reach Select Components. Select OpenManage IT Assistant, accept the default settings, and install. In order to satisfy the IT Assistant installation requirements, you may have to install additional software.
PAGE 13
Select File -> New Gateway Enter the IP address through which the Opengear unit/management LAN gateway is accessible to this client PC (e.g. 192.168.0.1). Enter the gateway username (e.g. delladmin) and password you set in the previous step. Click OK Once you have an Opengear gateway connection in place you need to establish a connection to the PowerEdge through that gateway: If you have already added the PowerEdge as a host, right click it and select Edit.
