Similar to the rack-switches PCT and PCT series the switch offers an out-of-band fast-ethernet port for management as well as a serial console connection, required for initial configuration.
The PowerConnect is initially released with firmware 5. The underlying operating system of the PCT is based on Linux 2. All M-series switches offer a combination of internal interfaces and external interfaces. The internal interfaces connect to the mezzanine card of the blade-servers in the Me enclosure.
In addition, with the recent firmware release, up to 6 Mk switches can now be stacked and managed through a single IP. Stacking is done by assigning multiple 10Gb Ethernet ports as stacking-ports.
All layer-2 ethernet switches have a family or model-number below the and are based on Marvell hardware. The switches with a model-number above are based on Broadcom hardware. Although each switch has its own firmware images; the options and capabilities on these switches are the same or similar. The PCT rack series continue to run in the major-release number 3: new features or capabilities released in the other switches under firmware 4 or 5 are not available for the PCT series.
All other switches that are based on Broadcom hardware run on major release 4 or 5. Bootcode[ edit ] All Powerconnect switches, including the series, have both bootcode and operational code where you can run older firmware versions on later bootcode. Bootcode is  backwards compatible: you can run firmware of a lower version then the boot-code version; when upgrading firmware you do NOT need to upgrade the boot-code unless specifically directed in the release note or by Dell support, but when downgrading you leave the newer boot-code in place On the level2 switches Marvell based the bootcode is delivered as a separate file that needs to be copied to your switch.
The multi-layer switches however have the bootcode and operational code distributed in one file: you download and prepare to activate the newer firmware and with a special command update bootcode the switch builds the new bootcode from the operational code information.
It is always possible to run a newer firmware operational code on a previous bootcode unless specifically noted in the release notes. In this case, the upgrade will automatically update the boot code during upgrade. Letting the unit completely rejoin the stack before updating any other unit is strongly advised, although updating the units individually not as part of a stack is always the safest route.
Firmware releases are backwards compatible and you can have switches of the same model in your network running on different firmware levels. Configuration files of older firmware can be used on the newest switches except for some small changes in configuration behavior that was introduced with introduction of firmware 4. Features[ edit ] The Broadcom-based multi-layer switches offer a wide range of layer-2 and layer-3 options, and new features are added all the time.
Until version 4. Management[ edit ] All Powerconnect switches can be configured via either a built-in web- GUI or the command line interface or CLI except for the entry-level layer 2 Powerconnects that only offer web-based configuration or can run in the un-managed mode.
A free version,  which only allows the user to manage up to 10 network devices, is available on the firmware page of the respective switches. Also the Cisco Catalyst 3xxx switches for the Me enclosure are still available.
