Component Description
1. I/O Module (2) Tw
o I/O modules (6 Gb/s SAS EBOD) provide connectivity to the
ContentServer 3000. 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.
