Component
Description
1. I/O Module (2)
Two I/O modules (12 Gb/s SAS EBOD) provide connectivity to the
ContentServer 4000. The system can operate with one or two
modules. If one of the modules fails in a two module system, the
other module will continue to operate. If the ContentStore is run with
a single module, the other I/O module bay must be filled with a blank
module.
CAUTION:
With Harmonic MediaGrid 4.0, SAS cables are not
hot-swappable. When replacing or removing a SAS cable, you
must first power down the associated ContentServer controller
using SystemManager, replace or re-connect the SAS cable,
and then power on the ContentServer controller by pressing
the power button on the front panel.
