Statement 1074

Caution To ensure proper airflow it is necessary to rack content security appliances using rail kits. Physically placing the units on top of one another or stacking without the use of the rail kits blocks the air vents on top of the appliances, which can result in overheating, higher fan speeds, and higher power consumption. We recommend that you mount your appliances in rail kits when you are installing them into the rack because these rails provide the minimal spacing required between the appliances. No additional spacing between the appliances is required when you mount them using rail kits.

When you are installing an appliance, use the following guidelines:

• Plan your site configuration and prepare the site before installing the appliance. See the Quick Start Guides for the Cisco x90 Series Content Security Appliances for the recommended site planning tasks.
• Ensure that there is adequate space around the appliance to allow for servicing the appliance and for adequate airflow. The airflow in the appliance is from front to back.
• Ensure that the air-conditioning meets the thermal requirements listed in the Appliance Specifications.
• Ensure that the cabinet or rack meets the requirements listed in the “Rack Requirements” section.
• Ensure that the site power meets the power requirements listed in the Appliance Specifications. If available, you can use an uninterruptible power supply (UPS) to protect against power failures.

Safety Recommendations

Use the information in the following sections to help ensure your safety and to protect the chassis. This information may not address all potentially hazardous situations in your working environment, so be alert and exercise good judgment at all times.

Observe these safety guidelines:

• Keep the area clear and dust-free before, during, and after installation.
• Keep tools away from walkways, where you and others might trip over them.
• Do not wear loose clothing or jewelry, such as earrings, bracelets, or chains that could get caught in the chassis.
• Wear safety glasses if you are working under any conditions that might be hazardous to your eyes.
• Do not perform any action that creates a potential hazard to people or makes the equipment unsafe.
• Never attempt to lift an object that is too heavy for one person.

Maintain Safety with Electricity

Warning Before working on a chassis, be sure the power cord is unplugged. Be sure to read the Regulatory and Compliance Safety Information document before installing the security appliance.

Follow these guidelines when working on equipment powered by electricity:

• Before beginning procedures that require access to the interior of the chassis, locate the emergency power-off switch for the room in which you are working. Then, if an electrical accident occurs, you can act quickly to turn off the power.
• Do not work alone if potentially hazardous conditions exist anywhere in your work space.
• Never assume that power is disconnected; always check.
• Look carefully for possible hazards in your work area, such as moist floors, ungrounded power extension cables, frayed power cords, and missing safety grounds.
• If an electrical accident occurs:

– Use caution; do not become a victim yourself.

– Disconnect power from the system.

– If possible, send another person to get medical aid. Otherwise, assess the condition of the victim, and then call for help.

– Determine whether the person needs rescue breathing or external cardiac compressions; then take appropriate action.

• Use the chassis within its marked electrical ratings and product usage instructions.
• The appliances are equipped with an AC-input power supply, which is shipped with a three-wire electrical cord with a grounding-type plug that fits into a grounding-type power outlet only. Do not circumvent this safety feature. Equipment grounding should comply with local and national electrical codes.

Prevent ESD Damage

ESD occurs when electronic components are improperly handled, and it can damage equipment and impair electrical circuitry, resulting in intermittent or complete failure.

Always follow ESD-prevention procedures when removing and replacing components. Ensure that the chassis is electrically connected to an earth ground. Wear an ESD-preventive wrist strap, ensuring that it makes good skin contact. Connect the grounding clip to an unpainted surface of the chassis frame to safely ground ESD voltages. To properly guard against ESD damage and shocks, the wrist strap and cord must operate effectively. If no wrist strap is available, ground yourself by touching the metal part of the chassis.

For safety, periodically check the resistance value of the antistatic strap, which should be between one and 10 megohms.

Site Environment

When planning the site layout and equipment locations, consider the information in the next section to help avoid equipment failures and reduce the possibility of environmentally caused shutdowns. If you are currently experiencing shutdowns or unusually high error rates with your existing equipment, these considerations may help you isolate the cause of failures and prevent future problems.

Power Supply Considerations

See the “Power Specifications” section for more detailed information about the power supplies.

When installing the chassis, consider the following:

• Check the power at the site before installing the chassis to ensure that it is free of spikes and noise. Install a power conditioner, if necessary, to ensure proper voltages and power levels in the appliance-input voltage.
• Install proper grounding for the site to avoid damage from lightning and power surges.
• The chassis does not have a user-selectable operating range. Refer to the label on the chassis for the correct appliance input-power requirement.
• Several styles of AC-input power supply cords are available for the appliance; make sure that you have the correct style for your site.
• If you are using dual redundant (1+1) power supplies, we recommend that you use independent electrical circuits for each power supply.
• Install an uninterruptible power source for your site, if possible.

Rack Requirements

This section provides the requirements for the standard open racks.

• The rack must be of the following type:

– A standard 19-in. (48.3-cm) wide, 4-post EIA rack, with mounting posts that conform to English universal hole spacing, per section 1 of ANSI/EIA-310-D-1992.

– The rack post holes can be square 0.38-in. (9.6 mm), round 0.28-in. (7.1 mm), #12-24 UNC, or #10-32 UNC when you use the supplied slide rails.

– For the Cisco C190, M190, S190, C390, M390, and S390 appliances, the minimum vertical rack space per appliance must be 1 RU, equal to 1.75 in. (44.45 mm).

– For the Cisco C690, M690, and S690 appliances, the minimum vertical rack space per appliance must be 2 RUs, equal to 3.5 in. (88.9 mm).

• If you are mounting a chassis in an open rack, make sure that the rack frame does not block the intake or exhaust ports.
• Be sure enclosed racks have adequate ventilation. Make sure that the rack is not overly congested as each chassis generates heat. An enclosed rack should have louvered sides and a fan to provide cooling air.
• In an enclosed rack with a ventilation fan in the top, heat generated by equipment near the bottom of the rack can be drawn upward and into the intake ports of the equipment above it in the rack. Ensure that you provide adequate ventilation for equipment at the bottom of the rack.
• Baffles can help to isolate exhaust air from intake air, which also helps to draw cooling air through the chassis. The best placement of the baffles depends on the airflow patterns in the rack. Experiment with different arrangements to position the baffles effectively

Equipment Requirements

The slide rails supplied by Cisco Systems for the appliance do not require tools for installation if you install them in a rack that has square 0.38-in. (9.6 mm), round 0.28-in. (7.1 mm), or #12-24 UNC threaded holes.

Slide Rail Adjustment Range

For 1-RU appliances, the slide rails for the appliance have an adjustment range of 24 to 36 in. (610 to 914 mm).

For 2-RU appliances, the slide rails for the appliance have an adjustment range of 26 to 36 in. (660 to 914 mm).

Step 3 Install the slide rails into the rack:

a. Align one slide-rail assembly front end with the front rack-post holes that you want to use.

The slide rail front-end wraps around the outside of the rack post and the mounting pegs enter the rack-post holes from the outside-front (see Figure 1-3).

Note The rack post must be between the mounting pegs and the open securing plate.

b. Push the mounting pegs into the rack-post holes from the front of the outside.

c. Press the securing plate release button, marked “PUSH.” The spring-loaded securing plate closes to lock the pegs in place.

d. Adjust the slide-rail length, and then push the rear mounting pegs into the corresponding rear rack-post holes. The slide rail must be level front-to-rear.

The rear mounting pegs enter the rear rack-post holes from the inside of the rack post.

e. Attach the second slide-rail assembly to the opposite side of the rack. Ensure that the two slide-rail assemblies are at the same height with each other and are level front-to-back.

f. Pull the inner slide rails on each assembly out toward the rack front until they hit the internal stops and lock in place.

Step 4 Insert the appliance into the slide rails:

Caution The appliance can weigh up to 67 pounds (59 kilograms) when fully loaded with components. We recommend that you use a minimum of two people or a mechanical lift when lifting the appliance. Attempting this procedure alone could result in personal injury or equipment damage.

Step 5 (Optional) Secure the appliance in the rack more permanently by using the two screws that are provided with the slide rails. Perform this step if you plan to move the rack with appliances installed.

With the appliance fully pushed into the slide rails, open a hinged slam latch lever on the front of the appliance and insert the screw through the hole that is under the lever. The screw threads into the static part of the rail on the rack post and prevents the appliance from being pulled out. Repeat for the opposite slam latch.

Install the Cable Management Arm (Optional)

Note The Cable Management Arm (CMA) is reversible left to right. To reverse the CMA, see Reverse the Cable Management Arm (Optional) before installation.

Step 1 With the appliance pushed fully into the rack, slide the CMA tab of the CMA arm that is farthest from the appliance onto the end of the stationary slide rail that is attached to the rack post (see Figure 1-6). Slide the tab over the end of the rail until it clicks and locks.

Step 2 Slide the CMA tab that is closest to the appliance over the end of the inner rail that is attached to the appliance (see Figure 1-6). Slide the tab over the end of the rail until it clicks and locks.

Step 3 Pull out the width-adjustment slider that is at the opposite end of the CMA assembly until it matches the width of your rack (see Figure 1-6).

Step 4 Slide the CMA tab that is at the end of the width-adjustment slider onto the end of the stationary slide rail that is attached to the rack post (see Figure 1-6). Slide the tab over the end of the rail until it clicks and locks.

Step 5 Open the hinged flap at the top of each plastic cable guide and route your cables through the cable guides as desired.
