Creating a Daisy-Chain of MSDEs
When you have more than 2 MSDEs, you need to daisy chain some of the MSDEs together on
each of the MSDE ports. Spread the MSDEs as evenly as possible on the MSDE ports to help
balance the load and overall environment performance.
To create a daisy-chain of two or more MSDEs:
1. Locate a short MediaShare F/C cable in the MediaShare F/C kit. Look for a cable with a 9-
pin connector on each end.
2. Attach the 9-pin connector on one end of the cable to the EXP 9-pin connector on the LCC on
the back of the first MSDE. Secure the cable with the thumbscrews on the cable connector.
3. Attach the 9-pin connector on the other end of the cable to the PRI 9-pin connector on the
LCC on the back of the second MSDE. Secure the cable with the thumbscrews on the cable
connector.
Powering Up the System
Avid strongly recommends that you use the following power up sequence to ensure that all
components are properly recognized and configured.
1. MEDIAswitch – Allow the switch approximately 15 seconds to complete its self-diagnostic
prior to moving on to the JBODs.
2. JBODs – Allow the JBODs approximately 15 seconds to complete communication with the
switch and allocate SCSI IDs.
Clients – Turn on only one system first to stripe as desired and to set up MediaShare (refer to
your MediaShare F/C Set Up and User’s Guide.) After initial set up of striping has been
completed all clients can be turned on simultaneously in the future.
