How to Secure the Cables to CMA Type A

Note - This procedure illustrates how to route and secure the power cords and the Ethernet cable to the cable management arm. Your system may use additional cables.

1. If necessary, slide the chassis smoothly out of the cabinet about 3 inches (7.62 cm).

Sliding the server out of the cabinet provides easier access to the cable management arm.

2. Locate the two metal fingers on the first section of the cable management arm and the three metal fingers on the third section of the cable management arm.

Note the Velcro straps in the first and center sections.

3. Locate the large oval cutout in the center section of the cable management arm.

The fingers, oval cutout, and straps enable you to route the cables and cords and secure them to the cable management arm. A single power cord is shown in the figure below to indicate a routing path.

This figure shows the oval cutout on the cable management arm.

4. Route the cables into the two fingers in the first section of the cable management arm.

Be sure you leave enough slack to ensure an adequate bend radius for the cables.

5. Group the cables and insert the group into the large oval cutout, as shown in the next figure.

Use the oval cutout in the center section to route a group of cables through the cable management arm. Be sure you leave enough slack around the hinge to ensure an adequate bend radius for the cables.

Note - Do not insert the cables into the other metal cutouts. Use those cutouts to access and manipulate the cables.

6. Route the cables into the three fingers in the third section of the cable management arm, as shown in the next figure.

7. Connect the power cords and data cables to the server ports.

See the Sun Fire V490 Server Administration Guide for more information about external ports.

Note - Do not secure the server to the front mounting rails until after you connect the cables and route them onto the cable management arm. It is easier to route the cables onto the cable management arm when the server is extended out of the rack.

8. Using the Velcro straps, secure the cords and cables to the first and center sections of the cable management arm.

This figure shows how to route the cables onto the cable management arm and the location of the Velcro straps.

9. Connect the outlet plug of each power cord to the power sequencer in the cabinet, or to a grounded AC power outlet.

Caution - Each outlet must connect the server to a 15A circuit for North America and Japan, and to a 10A circuit for Europe. Consult your local electrical codes for any additional requirements. See the instructions provide with your cabinet for information about the power sequencer.

Note - For increased server redundancy, connect the power cords to separate circuits.

10. Plug in the twisted-pair Ethernet (TPE) cable to the RJ-45 outlet to connect to your Ethernet network.

See your network administrator if you need more information about how to connect to your network.

11. Secure the server to the front vertical mounting rails using either four M6 screws or four 10-32 screws.

Installing and Securing Cables
to CMA Type B

Note - The following instructions apply to CMA Type B. If you have CMA Type A, see Installing and Securing Cables to CMA Type A.

Determining the Correct Mounting Location

Cable Management Arm Type B is reversable: it can be mounted on either side of the system. In order to ensure proper cable routing, Sun recommends you mount the end of the CMA closest to the back panel of the system on the same side of the system's PCI cards.

Follow these guidelines:

If your system has PCI cards on the left side of the back panel, mount one end of the CMA on the left inner glide, and the other end on the right slide assembly.

If your system has PCI cards on the right side of the back panel, mount one end of the CMA on the right inner glide, and the other end on the left slide assembly.

See TABLE 3-2 to determine the correct mounting location for the CMA.

TABLE 3-2 Determining correct CMA mounting location
Location of PCI cards	Left	Right
Inner glide mounting location of CMA	Left	Right
