Installing the DS-16M and DS-32M Rails Installing the DS-16M and DS-32M Rails This section describes the installation procedures for the DS-16M and DS-32M rails. The figures below show a front and rear view of four sets of rails installed in a 39U rack. Note that the rack is shown without the side skins.
Installing the DS-16M and DS-32M Rails DS-16M Rails Installation There are two different length rails: The short rails range between 20.5 inches to 27 inches. The long rails range from 27 inches to 34 inches. Each kit contains two different length rear rail mounts. Use the rail length that is appropriate for your rack/cabinet.
Installing the DS-16M and DS-32M Rails 1. Assemble the rails. The rails assembly consists of an adjustable rail, a C channel, and two washers and kep nuts. See the figure below. C channel Adjustable rail a. Insert the threaded posts on the C channel into the slot on the adjustable rail. b. Secure the adjustable rail to the C channel with two #10 flat washers and M5 kep nuts. Leave the nuts finger tight. Attach washers\nuts to threaded posts 2.
Installing the DS-16M and DS-32M Rails "Top" up and to the rack front 3. Adjust the length of the rail to fit between the channels in the rack/cabinet. NOTE: The rail flanges go to the inside of the channels. 4. Once the rails are adjusted to the correct length, tighten the kep nuts on the rail assembly. NOTE: If the side skins are removed on the rack/cabinet, you can tighten the kep nuts after you install the rails. 5. Align the holes of the front rail flange to the inside of the front channel.
Installing the DS-16M and DS-32M Rails M5 x 16 mm flat head screws (see the table on page 3). Leave the screws finger-tight, and tighten them after the switch is installed. See the figure below. DS-16M Round-Hole Channel, Rack Front (for example, the CLARiiON Rack/Cabinet) DS-16M Square-Hole Channel, Rack Front (Third-Party Rack/Cabinet) If you are installing the switch in a 40U cabinet, install a keyplate spacer on the outside of the channel as you secure the rail to the front channel.
Installing the DS-16M and DS-32M Rails 7. If you are installing the switch in a 39U cabinet, position the #10 washer and ball stud in the center hole, between the two M5 x 12 mm screws. Hand-tighten the ball stud. NOTE: The ball studs support the bezel. If you are installing the switch in a 40U cabinet, use an M5 x 12 mm screw to install the latch bracket in the center hole, over the keyplate spacer. See the figure below. Latch Bracket Keyplate Spacer Screw EMC2422 8.
Installing the DS-16M and DS-32M Rails 9. Secure the rail to a round-hole rear channel with 2 M5 x 12 mm pan-head screws (see the table on page 3), or secure the rail to a square-hole rear channel with 2 square-hole washers and M5 x 16 mm flat-head screws (see the table on page 3). Leave the screws finger-tight, and tighten them after the switch is installed. See the figures below.
Installing the DS-16M and DS-32M Rails DS-32M Rails Installation There are two different length rails: the short rails range from 20.5 inches to 27 inches. The long rails range from 27 inches to 34 inches. Each kit contains two different length rear rail mounts. Use the rail length that is appropriate for your rack/cabinet.
Installing the DS-16M and DS-32M Rails Select the appropriate length rails, and follow the steps below to install them. 1. Assemble the rails. The rails assembly consists of an adjustable rail, a C channel, and two washers and nuts. See the figure below. C channel Adjustable rail a. Insert the threaded posts on the C channel into the slot on the adjustable rail. b. Secure the rail to the C channel with two #10 flat washers and M5 kep nuts. Leave the nuts finger-tight. 2.
Installing the DS-16M and DS-32M Rails 3. Adjust the length of the rail to fit between the channels in the rack/cabinet. NOTE: The rail flanges go to the inside of the channels. 4. Once the rails are adjusted to the correct length, tighten the kep nuts. NOTE: If the side skins are removed on the rack/cabinet, you can tighten the kep nuts after you install the rails. 5. Align two of the holes of the front rail flange to two holes on the inside of the front channel.
Installing the DS-16M and DS-32M Rails DS-32M Round-Hole Channel, Rack Front DS-32M Square-Hole Channel, Rack/Cabinet Front If you are installing the switch in a 40U cabinet, use the appropriate screws to install the latch bracket (instead of the ball stud) to the outside edge of the channel as you secure the rail. To attach the bottom latch bracket screw, install an M5 clip nut over the aligning hole in the channel. See the following figure.
Installing the DS-16M and DS-32M Rails 8. Secure the rail to a round-hole rear channel with two M5 x 12 mm screws (see the table on page 3), or secure the rail to a square-hole rear channel with two square-hole washers and M5 x 16 mm screws (see the table on page 3). Leave the screws finger-tight, and tighten them after the switch is installed. See the figure below. DS-32M Round-Hole Channel, Rear DS-32M Square-Hole Channel, Rear 9. Repeat steps 1 through 8 for the other rail.
Installing the DS-16M2 and DS-32M2 Switches Installing the DS-16M2 and DS-32M2 Switches This section describes the procedures for installing the DS-16M2 and DS-32M2 switches in a rack/cabinet, including attaching the brackets on the switch. Both switches are installed in the rack/cabinet the same way. Note, however, that the DS-16M should be positioned at the top of the rack/cabinet, above the DS-32M. Mounting Bracket Installation NOTE: The mounting brackets are the same for both the DS-16M2 and DS-32M2.
Installing the DS-16M2 and DS-32M2 Switches ! CAUTION The kits include two (2) sets of screws. To avoid damaging the screw holes, be sure to check the labeling on the bags and use the appropriate set of screws for your chassis. The chassis product number is located on labels at the back and on the bottom of the chassis. Align middle hole first 3. Secure the bracket with five 6-32 x .31 flat-head screws (see the table on page 3). Tighten the screws fully. Fan end of switch 4.
Installing the DS-16M2 and DS-32M2 Switches 5. Push the switch further into the rack/cabinet until the hole in the front part of each bracket (the “L”-shaped end) aligns with the hole on the fixed rail. See the figure below. C channel Align hole in bracket with hole in the fixed rail 6. Tighten the front screws securing the rails to the front of the rack/cabinet. 7. Secure the brackets to the rails with two M3 x 8 mm pan-head screws (see the table on page 3), one on each side, as shown below.
Installing the DS-16M2 and DS-32M2 Switches Front View of 32-port Switch Installed in a 39U Rack Rear View of 32-port Switch Installed in a 39U Rack 8. Install the bezel by positioning and installing the bezel stud receptacles on the back of the bezel over the ball studs (39U rack) or latch brackets (40U rack) on the rail ends. 9. Push the bezel onto the ball studs or latch brackets until it snaps and locks into place. The illustration below shows an installed, unpainted 16-port bezel in a 39U rack. 10.
Installing the DS-16M2 and DS-32M2 Switches NOTE: There is a 3-inch space between the front of the switch and the back of the bezel. This is enough room to loop the cord up without pushing the bezel off. 12. When installing the DS-32M2 switch, the 2U spacing allows you to run the power cords between the switches. 13. Secure the power cords in the retainer clips, and route them down the trough along the edge of the rear of the rack. See the figures below.
Installing the DS-16M2 and DS-32M2 Switches ! CAUTION If you are removing the switches from the cabinet, you must remove the top switch from the back of the cabinet. You can remove all switches below the top switch from the front. 15. Attach the fibre-optic cables to the switch and run the cables from the switch to the appropriate device. Ensure each fibre-optic cable has a minimum bend radius of 2 inches. Copyright © 2002 EMC Corporation. All Rights Reserved.
