This chapter describes the procedures for rack-mounting, connecting the cables, and powering up the LightStream 1010 ATM switch at your site.
 | Caution Before installing the chassis in a rack, read the section "Safety with Electricity" in the chapter "Preparing for Chassis Installation" to familiarize yourself with the proper site and environmental conditions. Failure to read and follow these guidelines could lead to an unsuccessful installation and possible damage to the system and components. |
A rack-mount kit is included for mounting the switch in a standard 19-inch (48.7-centimeter) equipment rack with two unobstructed outer posts.
Following is the procedure for attaching the rack-mount kit and installing the switch in a wiring closet rack. Two or more people are needed to perform this procedure.
Be sure you have at least three or four feet of clearance behind the rack for maintenance. The intake and exhaust ports for cooling air are located on the front and rear and both sides of the chassis, so multiple switches can be stacked with little or no clearance in a rack. The chassis is 10.36 inches (25.9 centimeters) high.
Before rack-mounting the LightStream 1010 ATM switch, confirm that your rack-mount configuration conforms to the following criteria:
| Caution Before you mount the switch in a rack, make sure that: the rack is secure and in no danger of falling over; the area around the rack does not exceed a maximum ambient temperature of 104ºF (40ºC); and sufficient airflow exists around the rack. |
 | Warning Two people are required to lift the chassis. Grasp the chassis underneath the lower edge and lift with both hands. To prevent injury, keep your back straight and lift with your legs, not your back. To prevent damage to the chassis and components, never attempt to lift the chassis with the handles on the power supplies or on the interface modules. These handles were not designed to support the weight of the chassis. To see translated versions of this warning, refer to the appendix "Translated Safety Warnings." |
Refer to the section "Safely Lifting the Chassis" in the chapter "Preparing for Chassis Installation."
Following are the tools and equipment needed to install the chassis:
If you are installing the chassis in a rack, you will also need the following:
Take the following steps to attach the two L brackets to the switch chassis:
Step 1 Place the chassis on the floor or on a sturdy table as close as possible to the rack, with clearance to allow you to move around the chassis.
Step 2 Use a tape measure to measure the depth of the rack. Measure from the outside of the front mounting posts to the outside of the rear mounting strip. The depth must be at least 19.25 inches (39.4 centimeters), but not greater than 32 inches (81 centimeters).
Step 3 Measure the space between the inner edges of the left front and right front mounting posts to ensure that it is 17.75 inches (45 centimeters) wide. (The chassis is 17.25 inches [43 centimeters] wide and must fit between the mounting posts.)
Step 4 Open the rack-mount kit and refer to the component checklist in Table 3-1 to verify that all parts are included.
| Quantity | Part Description | Received |
|---|---|---|
2 | L brackets (left and right) |
|
6 | M4 Phillips countersunk-head screws |
|
8 | 12-24 x 3/4-inch Phillips binder-head screws |
|
8 | 10-32 x 3/4-inch slotted binder-head screws |
|
Step 5 Depending on your installation, remove the six cover attachment screws from either the front or the rear of the switch. (See Figure 3-1.)
Step 6 Attach the left and right L brackets using the six M4 Phillips countersunk-head screws provided in the rack-mount kit.
Step 7 Attach the left and right cable guides, if needed, using the six M3 Phillips flat-head screws provided in the cable mount bracket kit. (See Figure 3-2.)
The L brackets attach the chassis to the front mounting posts. You can mount the L brackets on either the front or rear of the chassis, whichever end will be in the front of the rack.
| Warning To prevent bodily injury when mounting or servicing this unit in a rack, you must take special precautions to ensure that the system remains stable. The following guidelines are provided to ensure your safety: |
| Warning Two people are required to lift the chassis. Grasp the chassis underneath the lower edge and lift with both hands.

Refer to the section "Safely Lifting the Chassis" in the chapter "Preparing for Chassis Installation."
Follow these steps to install the switch in an open rack that allows you to slide the chassis in from the front.
Step 1 Three people are required to perform this step.While referring to Figure 3-3, with a person positioned at either side of the chassis, grasp the bottom edge of the chassis with one hand near the front and the other near the back. Slowly lift the chassis in unison. Avoid sudden twists or moves, to prevent injury.
Step 2 Position the chassis in the rack as follows:
Step 3 A third person should install the 10-32 x 3/4 inch slotted binder head or 12-24 x 3/4 inch phillips-head mounting screws through the elongated holes in the L bracket and into the threaded holes in the mounting post.
Step 4 Use your tape measure and level to ensure that the chassis is installed straight and level.
Step 5 At the front of the chassis, perform the following steps:
Step 6 Make sure that your path to the rack is unobstructed.
The rack-mount installation is now complete.
Refer to the LightStream 1010 ATM Switch ASP Installation Guide and LightStream 1010 ATM Switch PAM Installation Guide publications for detailed port cabling information.
Connect the AC-input or DC-input power supply using the information in the chapter "Maintaining the LightStream 1010 ATM Switch Chassis" and the following sections:
After making the power supply connections you are ready to apply the power and begin configuration of your LightStream 1010 ATM switch. Proceed to the next chapter "Configuring the LightStream 1010 ATM Switch" to continue the chassis installation.
