Managing Ethernet Cables
A Dell PowerVault ML6000 library with FC I/O blades uses external Ethernet cables on the rear of the library
to provide connectivity between the LCB in the 5U Control Module and a 9U Expansion Module. The upper
and lower FC I/O blade bays within a 9U 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.
To organize Ethernet cables on the rear of the library, mount two wire saddles on the 5U 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 9U Expansion Module and at least
one FC 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 5U 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 5U Control Module’s power supplies. See Figure 13
on page 44 for the locations of these
holes.
2 Locate a specific hole that is drilled into the back of the 9U 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 9U
Expansion Module on the right side of the frame back plane. See Figure 13
on page 44 for the location
of this hole.
3 Insert a push rivet into the rivet hole on the blue hook-and-loop fastener. The head of the rivet should
be on the same side of the fastener as the plastic loop.
4 Firmly press the push rivet through the hole in the 9U Expansion Module described above. The hook-
and-loop fastener should now be secured to the library chassis.
5 Plug the one end of the Ethernet cable into one of the four Ethernet hub ports on the LCB.
6 Plug the other end of the Ethernet cable into the appropriate port on the 9U Expansion Module.
If the FC I/O blade is installed in the module's upper I/O blade bay, plug the cable into the Ethernet port
labeled UPPER. If the FC I/O blade or Ethernet Expansion blade is installed in the module's lower I/O
blade bay, plug the cable into the Ethernet port labeled LOWER.
7 Open the wire saddle nearest the LCB, place the Ethernet cable inside, and snap the wire saddle shut.
8 Repeat for the other wire saddle.
9 If there is excess Ethernet cable, loop the excess cable into a bundle in the shape of a figure-eight. The
bundle should be small enough to hold comfortably with one hand, or about six inches in length.
10 Wrap the bundle with the hook-and-loop fastener. Thread the strap through the plastic loop and tighten
the strap around the bundled cable. Secure the strap by pressing it down.
Note
If your 5U Control Module chassis does not have the drilled holes, use the
adhesive -backed wire saddle cable clamps in the location shown in Figure
13.
Note
If your module chassis does not have the drilled hole, use an M5 thumbscrew
to attach the black hook-and-loop fastener to the nearest available M5
threaded hole on the lower right of any module chassis.
