Installing an xDDF-21 patch panel
The xDDF-21 is installed above the XDM-300 shelf accessories.
To install an xDDF-21 patch panel:
1. Route the 2 x 50-pin SCSI cables leading from the PIM2_21 or PIM2_63/B
along the side of the rack to the location where the xDDF-21 patch panel
will be installed.
2. Before you install the patch panel, connect the SCSI cables leading to the
rear of the xDDF-21 patch panel. The cables are marked J1 and J2 and
should be connected to their respective connectors.
3. Leaving at least 100 mm free space above the XDM-300 shelf accessories
and below the xDDF-21, attach the patch panel to the rack rails and secure,
using the four supplied screws, washers, and nuts.
4. Connect the traffic cables to the front of the xDDF-21 patch panel, and
make a note of the appropriate channels on the identification label on the
inside of the panel door.
