Managing Ethernet
Cables 12
A Scalar i500 library with FC I/O blades or Ethernet Expansion 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/Ethernet Expansion 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 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 a total of four FC I/O
blades and/or Ethernet Expansion 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 FC I/O blade or Ethernet Expansion
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 Figure 50
on page 326 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 Figure
50 on page 326 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 50
.
