Installing the support rails for the SAN Volume Controller 2145-4F2

You must install the support rails that hold the SAN Volume Controller 2145-4F2.

1. Check the labels on the support rails. Each rail has a label that indicates which is the front end of the rail and whether the rail is for the left or right side of the rack. Perform this procedure for both rails.
2. Put your index finger against the side of the latch-lever,  1  in Figure 1, and put your thumb against the front of the latch-lock  2 .

   •  1  Latch lever
   •  2  Latch lock
3. Gently push the latch lock  2  away from the rail as you move the latch lever  1  toward the far end of the rail (Figure 2). The latch-lock carrier assembly slides against the spring tension.

   •  1  Latch lever
   •  2  Latch lock
4. Continue to slide the latch-lock carrier for approximately 13 mm (0.5 in). The latch-lever engages a hole in the back bracket assembly and holds the latch-lock carrier in the retracted position.
5. Push the back rail bracket  3  (Figure 3) toward the front of the rail until it stops. The rail is now at its shortest adjustment.

   •  1  Latch-lever
   •  2  Latch-lock
   •  3  Back rail bracket
6. Place the front end of the left rail in the rack cabinet. Align the top of the front bracket  1  (Figure 4) with the required EIA marking that is on the rack.

   •  1  Front bracket
   •  2  Rack-mounting flange
   •  3  Locating pins
7. Align the locating pins  3  with the holes that are in the rack-mounting flange.
8. Push the latch lock  2  (Figure 5) away from the rail to release the carrier. The latch-lock carrier slides toward the front of the rack and the locating pins project through the holes that are in the front flange and in the front rail bracket.
   Important: Ensure that the locating pins are fully extended through the front rail bracket.

   •  2  Latch-lock
9. Push the back rail bracket toward the rear of the rack and align the locating pins with the rack-mounting flange.
10. Push the latch lock  2  away from the rail to release the carrier. The latch-lock carrier slides toward the rear of the rack, and the locating pins project through the holes that are in the rear flange and in the rear rail bracket.
    Important: Ensure that the locating pins are fully extended through the rear rail bracket.
11. On the rear of each rail, press the blue release tab and slide the shipping bracket off the slide rail. Store the shipping bracket for further use.
