This chapter provides instructions for installing system hardware into a rack and contains the following sections:
Use the instructions in this chapter to install individual Cisco MGC components in a rack.
Check that you have the following tools and understand how to prepare the rack for installing the equipment.
Make sure that you have the following standard tools before beginning the installation:
The spacing between the Cisco MGC hardware components is important for several reasons. Cabling is provided for some configurations and will work only for certain vertical and horizontal orientations of the equipment. Vertical space is required above certain host computers to allow access to the circuit cards that are located inside the computer. See the following instructions and diagrams for details on where to locate and how to install the Cisco MGC hardware.
Figure 3-1 defines the point of reference and terminology used in locating the equipment in the frame. The lowest position available for mounting in a frame is defined as position 0. The position numbers increase toward the top of the frame. The rack positions are defined in terms of vertical rack units. One rack unit equals 1.75 inches.
The Sun Netra t 1400 and Sun Netra t 1405 can be deployed in both single-host and dual-host configurations. Figure 3-2 shows the recommended vertical orientation of the Sun Netra t 1400 and
Sun Netra t 1405 in a typical continuous-service dual-host configuration using an optional Cisco SLT.
The Sun Netra t 1400 and Sun Netra t 1405 have been designed to mount in 19-inch, 23-inch, 24-inch, and 600-millimeter nominal frame openings. Cooling air is brought in from the front and is exhausted out the back of the units. A minimum of 200 square centimeters is required at the front for air intake and at the rear for air exhaust. If the equipment is placed in a frame with front and rear doors, the front doors must be ventilated to allow air intake, and the rear or top must be ventilated to allow air exhaust. Refer to the "Forced Air Cooling Requirements" section in the Sun Netra t 1400/1405 Installation and User's Guide for more information. This guide ships with the Sun Netra t 1400 and the
Sun Netra t 1405.
The Sun Netra t 1120 and Sun Netra t 1125 can be deployed in both single-host and dual-host configurations. Figure 3-3 shows the recommended vertical orientation of the Sun Netra t 1120 and
Sun Netra t 1125 in a typical continuous-service dual-host configuration using an optional Cisco SLT.
The Sun Netra t 1120 and Sun Netra t 1125 have been designed to mount in 19-inch, 23-inch, 24-inch, and 600-millimeter nominal frame openings. Cooling air is brought in from the front and is exhausted out the back of the units. A minimum of 200 square inches is required at the front for air intake and at the rear for air exhaust. If the equipment is placed in a frame with front and rear doors, the front doors must be ventilated to allow air intake, and the rear or top must be ventilated to allow air exhaust. Refer to the "Forced Air Cooling Requirements" section in the Sun Netra t 1120/1125 Installation and Basic Maintenance Guide for more information. This guide ships with the Sun Netra t 1120 and
Sun Netra t 1125.
The Sun E450 is deployed in both single and dual configurations. In addition, there can be other hardware included depending upon whether the configuration involves optional ARUs for alarms.
Figure 3-4 shows the recommended vertical and horizontal orientation of the Sun E450 for single and dual checkpointing configurations. Use this diagram to locate the hardware in the equipment rack. The rack should be loaded from the lowest point to the highest point to maximize rack stability. These frames must be located side-by-side as closely as possible.
 |
Note The Sun E450 can mount in any standard four-post 19-inch EIA rack with a minimum depth of 30 inches. |
The Sun E450 requires adequate space for intake and exhaust to maintain proper cooling. Allow
92 square inches of unrestricted airflow into the front of the system and 97 square inches of unrestricted exhaust port at the rear of the system. Maintain a minimum of 1.5 inches clearance between the
Sun E450 and any front or rear doors.

The Serial Port Expander is a cable assembly consisting of a cable and a box with eight ports. The purpose of the assembly is to increase the number of serial ports available. These ports are used to connect the ARU (when used) to the host computer. It is also the link between the two host computers in a dual noncheckpointing system.
The Serial Port Expander does not have any built-in features to allow it to be attached to the frame or cabinet in which the other equipment is installed. Instead, the expander can rest on top of the host computer or other equipment, or, for a more secure installation, a secondary bracket can be used.
The Serial Port Expander can be mounted similarly above the Sun E450. Figure 3-5 shows the Serial Port Expander attached to a bracket above a Sun Netra t 1120 or Sun Netra t 1125, which is then attached to a frame or cabinet. The Serial Port Expander can be mounted similarly above the Sun E450.
The Serial Port Expander is attached to the bracket with tie-wraps. The brackets should be attached to the frame or cabinet in the space above the host computer on the Sun Netra t 1120, Sun Netra t 1125, and the Sun E450.
This section contains instructions for installing the Cisco SLT. This is an optional feature, but it is recommended.
Installation might require some tools and equipment that are not provided as standard equipment with the router. Following are the tools and parts required for a typical router installation:
|
Note For more information on cable specifications, see the document Cisco Modular Access Router Cabling Specifications on the Documentation CD-ROM that accompanied your router package, and on Cisco Connection Online. |
This section describes the procedures for rack-mounting the chassis. Figure 3-3 shows how the equipment mounts in the rack.
|
Note Individual components do not ship with a rack; you must supply your own rack and mounting hardware. A preracked chassis comes with brackets for use with a 19-inch rack or, if specified in your order, optional larger brackets for use with a 23-inch or 24-inch rack. The brackets are shown in Figure 3-6 and are sold separately. |
|
Warning Make sure that your rack is bolted to the floor. |
|
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 Make sure that your equipment rack is properly ventilated. |
Figure 3-6 identifies the brackets to use with a 19-inch or a 23- or 24-inch rack.
Identifying the Brackets
To install the chassis in a rack, attach the brackets in one of the following ways:
|
Note Use the Cisco-supplied screws for this installation. |
|
Note If you are installing a Cisco SLT in a 19-inch rack with a 17.5-inch opening, orient the rack-mount brackets so that, when installed, they do not increase the width of the chassis. (See Figure 3-7.) If you are installing a Cisco SLT in a 19-inch EIA-standard rack with a 17.75-inch opening or a 23- or 24-inch rack, orient the rack-mount brackets so that they increase the width of the chassis when installed. (See Figure 3-8.) |
The following illustrations show how to connect the bracket to one side of the chassis. The second bracket connects to the opposite side of the chassis.
|
Note When installed in a 19-inch rack with a 17.75-inch opening, the Cisco SLT protrudes beyond the front of the rack. |
After the brackets are secured to the chassis, you can rack-mount it. Using screws that you provide, attach the chassis to the rack. (See Figure 3-12 and Figure 3-13).
For step-by-step procedures for terminating signaling links, see the "Configuration Tasks" section in the Cisco document, Cisco 2600 Series SS7 Signaling Link Termination. For more information about installing the Cisco SLT, see the Cisco 2600 Series Hardware Installation Guide.
 |
Caution A standard rack-mount kit is included for mounting the switch in a standard 19-inch (48.3-centimeter) equipment rack with two unobstructed outer posts, with a minimum depth (between the front and rear mounting posts) of 19.25 inches (48.9 centimeters) and a maximum depth of 32 inches (81.3 centimeters). This kit is not suitable for use with racks with obstructions (such as a power strip) that could impair access to switch field-replaceable units (FRUs). |
|
Caution Before installing the chassis in a rack, read the Regulatory Compliance and Safety Information for the Cisco Media Gateway Controller document and "Cisco Media Gateway Controller Product Introduction," in this document 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. |
Before rack-mounting the switch, ensure the following:
The following tools and equipment are required to install the chassis:
The following tools and equipment are required to install the chassis in a rack:
Use this procedure to install the Catalyst 5500 switch in a rack:
a. Place the chassis on the floor or on a sturdy table as close as possible to the rack. Leave enough clearance to allow you to move around the chassis.
b. Install the power supplies in the chassis.
c. 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 (48.9 centimeters) but not greater than 32 inches (81.3 centimeters).
d. Measure the space between the inner edges of the left-front and right-front mounting posts to ensure that it is 17.75 inches (45.09 centimeters) wide. (The chassis is 17.25 inches [43.8 centimeters] wide and must fit between the mounting posts.)
e. Open the rack-mount kit and use the checklist in Table 3-6 to verify that all parts are included.

2 | Shelf brackets |
|
1 | Crossbar bracket |
|
2 | M3 Phillips pan-head screws |
|
Step 2 Note that the two shelf brackets support the weight of the chassis in the rack. Install the shelf brackets as follows:
|
Caution If the rack is on wheels, ensure that the brakes are engaged or that the rack is otherwise stabilized. |
a. Position the shelf brackets in the rack (see Figure 3-14).
b. Secure the shelf brackets by using six (three per side) 12-24 x 3/4-inch or 10-32 x 3/4-inch screws.
c. Attach the crossbar bracket to the back of the shelf brackets using two M3 screws.
|
Note No shelf is required with this assembly; the shelf brackets support the chassis in the rack. |
Step 3 Note that the L-brackets connect the chassis to the rack. Install the L-brackets by attaching the left and right L-brackets using the ten M4 Phillips countersunk-head screws provided in the rack-mount kit. (See Figure 3-15.)
|
Note Some equipment racks provide a power strip along the length of one of the rear posts. If your rack has this feature, consider the position of the strip when planning fastener points. Before you install the L-brackets on the chassis, determine whether you will install the chassis from the front or the rear of the rack. |
|
Note If you are installing cable guides, place the cable guides inside the L-brackets, between the L-bracket and the chassis. Secure the cable guides to the chassis using the same screws (and chassis holes) as the L-brackets. (See Figure 3-15.) The cable guides and screws are provided in the cable management kit. |
Step 4 Install the chassis in the rack as follows:
|
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. |
|
Note You should have a third person available to assist in this step. |
a. With a person standing at each 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.
b. Position the chassis in the rack as follows (see Figure 3-16):
c. Place the chassis on the shelf brackets.
d. Align the mounting holes in the L-bracket with the mounting holes in the equipment rack.
e. A third person should install the 10 (5 per side) 12-24 x 3/4-inch or 10-32 x 3/4-inch screws through the elongated holes in the L-bracket and into the threaded holes in the mounting post.
f. Use a tape measure and level to ensure that the chassis is installed straight and level.
Step 5 Check the ejector levers to ensure that the supervisor engine and all switching modules are installed securely.
Step 6 Tighten any loose captive installation screws on the supervisor engine and switching modules.
Step 7 Connect the power supplies to the site power by following the procedures in "Power and Grounding," in the "Connecting Ancillary Equipment" section.
|
Note Do not turn on the power supplies at this point. |
For more information on making LAN and WAN connections, see "Connecting to a Network" in "Cabling and Connections." See also the hardware guides included in your router package.
Use the information in this section to install components that are specific to your configuration option.
Use Table 3-5 to determine the hardware you will need based on your configuration option. See Figure 3-3 or Figure 3-4 to determine where the hardware should be located in the equipment frame.
|
Note The ARU is not used with the Sun Netra t 1400, the Sun Netra t 1405, the Sun Netra t 1120, or the Sun Netra t 1125 in this release. |
Orient the ARU so that the ground symbol is positioned in the top right corner of the unit when viewed from the front (see "Power and Grounding," for more information about grounding your equipment). Secure the ARU to the frame using four screws and toothed locked washers. Use screws that are compatible with the equipment rack chosen. Toothed lockwashers must be used to ensure that the ARU is grounded to the equipment frame. The minimum screw size should not be less than 10-32 (M5).
Use Table 3-3, Table 3-4, and Table 3-5 to determine the hardware you will need based on your configuration option. See the cabling table that applies to your configuration option in "Cabling and Connections," for information on connecting the Serial Port Expander.
Use the information in Appendix A, "Sun Netra t 100 and Sun Netra t 105," to install the BAMS components that are specific to your configuration option.
The Cisco MGC hosts support the 10/100 Ethernet card.
The 10/100 Ethernet card is installed for you at the factory. If you need to replace a failed card or add additional capacity, see "Maintenance."
The Cisco SLT has built-in LAN connections that provide single or dual Ethernet ports (depending on model). Cisco SLT series routers also include one network module slot and two WAN slots that accept a variety of network modules and interface cards.
The Cisco MGC configurations require the following connections:
