Rack-Mount Kit Overview In Telco-type installations, you can install the chassis so that the ends of the chassis are approximately centered on two posts. Figure 3 shows a typical center-mount installation. Caution To maintain a safe center of gravity in Telco-type installations (shown in Figure 3), the front and rear of the chassis are approximately centered on the mounting posts. Figure 3 Typical Center-Mount Installation In a 2-post, 4-post, or Telco-type installation, you can flush-mount the c

Prerequisites Prerequisites Before you begin this installation, review the safety guidelines in this section to avoid injuring yourself or damaging the equipment. This section also provides descriptions of the tools and parts you need to perform this installation, and guidelines for planning the rack location so that you can access the system components when necessary and maintain trouble-free operation. If you are mounting a chassis that is already installed, you will need to disconnect all pow

Prerequisites Safety Guidelines Review the following guidelines to help ensure your safety and protect the equipment from damage during the installation. Warning Before working on a system that has an on/off switch, turn OFF the power and unplug the power cord. (For translations of this safety warning, refer to the section “Power Disconnection Warning” on page 29.) Warning Do not touch the power supply when the power cord is connected. For systems with a power switch, line voltages are present w

Prerequisites • Ensure that your footing is solid and balance the weight of the object between your feet. • Lift the object slowly; never move suddenly or twist your body as you lift. • Keep your back straight and lift with your legs, not your back. If you must bend down to lift the chassis, bend at the knees, not at the waist, to reduce the strain on your lower back muscles. (See Figure 5.) • Grasp the underside of the chassis exterior with both hands. Warning Two people are required to lift th

Prerequisites Safety with Electricity Follow these basic guidelines when working with any electrical equipment: • Before beginning any procedures requiring access to the chassis interior, locate the emergency power-off switch for the room in which you are working. • Disconnect all power and external cables before installing or removing a chassis. • Do not work alone if potentially hazardous conditions exist. • Never assume that power is disconnected from a circuit; always check. • Do not perform

I O Prerequisites When you replace the power supplies, remember to engage all of the safety features on each supply. The power supplies feature the following three safety interlock features: • A safety interlock on/off switch (see Figure 6) prevents the power supply from being removed from the chassis when the power supply switch is in the on (|) position. When the switch is on, a metal tab extends into a slot in the chassis. When the switch is turned off (O), the tab retracts into the power sup

Prerequisites Rack Stability When installing the chassis in any rack that is not secured to the floor or overhead structure, place the chassis in the lower half of the rack. A fully-configured chassis weighs 145 pounds (65.8 kg), and a shift in the weight distribution (during the installation or later as a result of disturbance to the rack) can cause the rack to fall. Figure 7 Chassis Footprint and Outer Dimensions Power supply/interface processor end 10" clearance required for 16" clearance requi

Prerequisites Also, when installing the chassis in Telco-type racks, ensure that the rack is secured to the floor or otherwise stabilized. Center-mount the chassis if possible (and practical for your installation). Doing so places the center of gravity closest to the center of the mounting posts. Figure 8 shows the center of gravity for both center-mounted and flush-mounted installations. (The center of gravity will shift somewhat depending on which end of the chassis is positioned at the front of

Prerequisites Rack Dimensions and Site Layout For complete site requirements and recommendations, refer to the Cisco 7000 Hardware Installation and Maintenance or Cisco 7507 Hardware Installation and Maintenance publications. To help maintain trouble-free operation, consider the following precautions when planning your rack installation: • Place the chassis in a location with sufficient access to power and network interface cables. Avoid straining cables or routing them near traffic paths or power

Shielded side Installation Installation The following sections describe the procedures for mounting the chassis in a 19-inch equipment rack with two or four mounting posts. Before proceeding, review the guidelines and recommendations in the section “Prerequisites” on page 7 to protect your safety, to maintain sufficient clearance around the rack during and after the installation, and to ensure proper airflow through the chassis after the installation. Warning To avoid potentially serious bodily in

Installation After you install both brackets in the rack, you must connect the spanner bar on each bracket to the opposite bracket. The spanner bars are required to prevent both ends of the brackets (at the front and rear of the rack) from separating or drifting apart. The cutouts in the brackets are to accommodate the ear brackets that attach to the chassis to the rack. (Refer to Figure 2 on page 4.) To install the brackets in the rack, you will secure each bracket to a rack post with three 10-

Installation Step 4 Slide the bracket up and down along the mounting post to align the mounting holes in the bracket with those in the rack post. Step 5 While supporting the bracket with one hand, use the other hand to insert a 10-32 x 5/8-inch, Phillips pan-head screw through the bottom mounting hole on the front of the bracket and into the rack post. (See Figure 10.) Note Finger tighten the pan-head screw, but do not tighten it because you might need to adjust these screws when attaching the s

Installation Attaching the Chassis Ears The ears attach directly to the chassis with four M4 x 10-mm, flat-head screws. Attach the ears to the chassis before you slide the chassis onto the brackets and back into the rack. After you slide the chassis into the rack, insert a 10-32 x 5/8-inch pan-head screw through each of the captive grommets on the ears and through the rack-mounting strips. The ears do not bear the weight of the chassis, but prevent it from walking, or sliding horizontally out of
