Managing Ethernet
Cables 7
A Scalar i500 library with FC I/O blades uses external Ethernet cables on
the rear of the library to provide connectivity between the LCB in the
control module and an expansion module. The upper and lower FC I/O
blade bays within an expansion module each have a corresponding
Ethernet port on the back of the module. Running an Ethernet cable
between this port and one of the Ethernet hub ports on the LCB
establishes Ethernet connectivity between the FC I/O blade and the LCB.
The LCB provides ports for up to four Ethernet cables on its internal
Ethernet hub. This allows the library to support up to four FC I/O blades.
To organize Ethernet cables on the rear of the library, mount two wire
saddles on the control module to route the Ethernet cable(s) to the right
side of the library. Mount a blue hook-and-loop fastener to each module
and then secure the Ethernet cables with the fastener.
Ethernet cables and Ethernet hook-and-loop straps that are shipped with
the library are blue in color.
Apply the following procedure to any library that contains at least one
expansion module and at least one I/O blade.
To secure an Ethernet cable to the library frame using a cable tie:
1 Facing the rear of the library, install the two push-in wire saddle
cable clamps onto the control module chassis. Push the rivet of one
clip into the hole drilled into the cover plate located to the right of the
LCB. Push the rivet of the other clip into the hole located near the
extreme right side of the library, below the control module’s power
supplies. See Figure 25
for the locations of these holes.
2 Locate a specific hole that is drilled into the back of the expansion
module for the hook-and-loop strap. This hole is located on the rear
of the library, about three inches from the bottom of the expansion
module on the right side of the frame back plane. See Figure 25
for
the location of this hole.
Note: If your control module chassis does not have the drilled
holes, use the adhesive -backed wire saddle cable clamps
in the location shown in Figure 25
.
