BMC VLAN Tagging Support

The BMC supports VLAN (Virtual LAN) tagging for network traffic. VLANs are configured on the network switch and are given a VLAN ID or tag. Ports on the switch can belong to one or more VLAN and can have one of the following VLAN settings:

•Tagged — The packets coming out of the switch port contain the VLAN tag. In this case you should enable VLAN tags on the BMC and set the BMC VLAN tag (or ID) to the same value as the switch port. Otherwise the BMC will not respond to incoming network traffic. Note that setting a VLAN tag on the BMC also causes the BMC to insert the VLAN tag to all outgoing network packets.

•Untagged — The packets coming out of the switch port do not contain the VLAN tag. In this case you should disable VLAN tags on the BMC. By default, VLAN tags are disabled on the BMC.

NOTE: See the Dell PowerConnect 5316M CLI Reference Guide for more information about using

the VLAN commands.

Network Connectivity After Restart or Power-up

After the server chassis is powered-up or the PowerConnect™ 5316M Ethernet Switch Module (ESM) is rebooted or power cycled, the ESM will require approximately one minute and forty-five seconds to become fully operational. In addition, the ESM may require up to sixty seconds to establish the links to external Ethernet devices if the spanning tree protocol is enabled on the external ports of the ESM. See the Dell PowerConnect 5316M Systems Getting Started Guide for information on how to determine when the ESM is fully operational.

Integrated Mirroring Configurations

The following items provide updates for setting up and using integrated mirroring:

•The hard-drive status indicator does not display any status information until after the operating system driver initialization has occurred. To check for status information of a hard drive prior to operating system load, use <Ctrl><m> during POST. See the Dell PowerEdge Expandable RAID Controller 4/IM User’s Guide for more information. During normal operation, the status indicator is off.

NOTE: The hard-drive activity indicator functions normally before and after the operating system driver initialization.

NOTICE: If you use a drive with existing data, the data will be cleared before the hard drive is added to a mirror.

•It is recommended that any replacement drives should be blank and not previously configured.

•It is recommended that you replace hard drives in an integrated-mirror configuration with drives of the same capacity.
