Connecting the LRM/MACsec Adapter to the Host Switch and to Power

Before connecting the LRM/MACsec Adapter to the host switch, install it in the equipment rack using one of the options described in Installing an LRM/MACsec Adapter.

The LRM/MACsec Adapter connects to two ports the host switch, providing LRM and/or MACsec functionality for those ports. The adapter also draws power from the host switch.



Connect the adapter to the host switch using only the SFP cable that is provided for this purpose. The use of other cables can damage the equipment.

To connect an LRM/MACsec Adapter to its host switch, follow these steps:

  1. Insert one of the 50 cm SFP cables, included with the adapter, into Host Port1 on the front of the LRM/MACsec Adapter.

    This SFP cable is provided especially for use with the LRM/MACsec Adapter, and is labeled as such. It is not a standard SFP cable.

  2. Insert the other end of the cable into an SFP port on the switch.
  3. Repeat steps 1 and 2 to connect Host Port2 to the switch.

    Both Host Port1 and Host Port2 must be connected to the same host switch.

  4. If additional power is needed, attach a USB cable to the adapter's USB connector and to a power source.

    The LRM/MACsec Adapter receives power through its connection to the host switch‘s SFP port. Additional power is supplied through a USB cable that connects the adapter to a power source. The USB cable is required for MACsec connections. It is optional for LRM-only connections.

  5. When the LRM/MACsec Adapter is connected to the host switch, verify that the adapter‘s power LED turns on.

    If the power LED does not turn on, recheck the connections from the adapter to the switch and to the optional power source.

Refer to the Security chapter in the ExtremeXOS 30.7 User Guide for information about configuring the host switch to work with the LRM/MACsec Adapter.
