Management Port Media Converter

The capability to configure management media port converter is supported on the S6000 platform.

Starting with Dell Networking OS Release 9.3.0.0, copper Ethernet network management connectivity for

power distribution units (PDUs) is supported, without the need to provision an additional network switch.

A unique, dedicated special media converter is provided and it can be inserted in to any front-panel 40G

interface. This converter supports 10M, 100M, 1G Ethernet speeds. Although these ports are used for

management connectivity, the OS considers the traffic traversing through these ports as traffic passing

through any other data port.

To support the connectivity between the QSFP port of S6000 and the Base-T port of the PDU, a special

breakout Media Converter has been designed, with one end as the QSFP module and the other end with

4 RJ45 connectors to provide 4x 10/100/1000Base-T functionality.

When the media converter is inserted into the device and is detected by the switch, you can perform the

following tasks:

Configure the 10, 100 or 1000Base-T operation through an Serial Gigabit Media Independent Interface

(SGMII) interface.

The S6000 platform does not support SGMII mode with autonegotiation. To negotiate with the peer

PDU, a new physical layer (PHY) component is provided. The Media converter supports SGMII

autonegotiation with peer PDUs.

Also, the S6000 platform does not support half-duplex mode at any speed and only full-duplex mode of

operation is supported. Therefore, support for full-duplex is made available for speeds of 10M and 100M,

although PDUs support half-duplex mechanism.

Management Port Media Converter Components

The media converter is a 40G to 4 x 10/100/1000Base-T converter. The following are the elements of the

media converter:

• Electrically erasable programmable read-only memory (EEPROM) in Dell standard to provide vendor

details: I2C Address : 0x50 (7-bit)

• 10/100/1000 Base-T Gigabit Ethernet transceiver-4 per QSFP; 1 chip per fanout port ; I2C Address:

0x52 (7-bit)

• I2C Multiplexer- PCA9546A: 4 channel I2C bus switch. 1 per QSFP.

– I2C Address: 0x74 (7-bit)

– I2C Mux is used to select one of the four PHY54616s.

All three components of EEPROM, BCMPHY, I2C Mux are accessed using I2C, with their unique

addresses.
