Chapter 2: Spectrum system installation
• When setting up an EFS Ethernet, you must connect your Ethernet cable between corresponding EFS
Ethernet ports on the MediaDirectors. Do not use any other Ethernet ports for this purpose.
• Refer to the
SystemManager User Guide
for instructions on configuring a Spectrum system with EFS.
CAUTION:
Make sure each MediaDirector is running the same version of Spectrum
software and each has an EFS license installed BEFORE connecting the EFS Ethernet or
shared storage cables
NOTE:
For ease of explanation, the diagram in this section does not show the
MediaStores or SAS cabling. EFS requires SAS cabling between MediaDirectors and
MediaStores.

1. Make sure the MediaStores are connected via SAS.
2. On the Ethernet card assigned to EFS on the first MediaDirector, connect Ethernet cables to the first
two EFS Ethernet ports. Connect the other ends of the cables to the corresponding EFS Ethernet
ports on the second MediaDirector.
3. On the Ethernet card assigned to EFS on the first MediaDirector, connect Ethernet cables to the last
two EFS Ethernet ports. Connect the other ends of the cables to the first two EFS Ethernet ports on
the third MediaDirector.
4. On the Ethernet card assigned to EFS on the second MediaDirector, connect Ethernet cables to the
last two Ethernet ports. Connect the other ends of the cables to the last two Ethernet ports on the third
MediaDirector.
Connecting 4 MediaDirector 2252B-DS units in an EFS configuration
For the MediaDirector 2252B-DS, you can configure four units in an extended file system (EFS)
configuration using the EFS Ethernet ports.
Please note the following about cabling the MediaDirector 2252B-DS units with EFS Ethernet:
