This section provides the following topics:

Unpacking and Inspecting the Switch

Before you install a new chassis, you need to unpack and inspect it to be sure that you have all the items that

you have ordered and verify that the switch was not damaged during the shipment. If anything is damaged or

missing, contact your customer representative immediately.

We recommend that you use a mechanical lift when the chassis is being moved or lifted. Fully loaded, Cisco

MDS 9706 chassis can weigh up to 325 lb (147.5 kg), Cisco MDS 9710 chassis can weigh up to 449.5 lb

(203.8 kg), and Cisco MDS 9718 chassis can weigh up to 923 lb (419 kg).

Caution

When handling switch components, wear an ESD strap and handle modules by the carrier edges only. An

ESD socket is provided on the chassis. For the ESD socket to be effective, the chassis must be grounded either

through the power cable, the chassis ground, or metal-to-metal contact with a grounded rack.

Caution

Keep the shipping container for use when moving or shipping the chassis in the future. The shipping carton

can be flattened and stored with the pallet.

Installing the Cisco MDS 9700 Series Switches

Required Equipments

• Grounding cable (6 AWG recommended), sized according to local and national installation

requirements; the required length depends on the proximity of the Cisco MDS 9700 Series switch

to proper grounding facilities.

• Crimping tool large enough to accommodate girth of the DC lug

• Wire-stripping tool

For the Cisco MDS 9700 Series, you need a mechanical lift to handle the weight of the fully-loaded chassis.

Installation Guidelines

Follow these guidelines when installing a Cisco MDS 9700 Series chassis.

• Plan your site configuration and prepare the site before installing the chassis. We recommend that you

use the site planning tasks listed in Appendix 8, “Site Planning and Maintenance Records.”

• Ensure that there is adequate space around the switch to allow for servicing the switch and for adequate

air flow. Air flow requirements are listed in Appendix 6, “Technical Specifications” .

•Ensure that the air-conditioning meets the heat dissipation requirements listed in Appendix 6, “Technical

Specifications.”

• Ensure that the rack meets the requirements listed in Appendix 2, “Rack Requirements.”

•Ensure that the site power meets the power requirements listed in Appendix 6, “Technical Specifications.”

You can use an uninterruptible power supply (UPS) to protect against power failures.

Avoid UPS types that use ferroresonant technology. These UPS types can become

unstable with systems such as the Cisco MDS 9000 Family, which can have

substantial current draw fluctuations because of fluctuating data traffic patterns.

Caution

• Ensure that circuits are sized according to local and national codes. For North America:

• The 3000-W AC power supplies require a 20-A circuit.

If you are using 200/240 VAC power sources in North America, the circuits must be protected by

two-pole circuit breakers.

To prevent loss of input power, ensure that the total maximum loads on the circuits

supplying power are within the current ratings of the wiring and breakers.

Caution

• Record your installation and configuration information as you work. See Appendix 8, “Site Planning

and Maintenance Records.”

• Use the following screw torques when installing the switch:

• Captive screws: 4 in-lb

• M3 screws: 4 in-lb

• M4 screws: 12 in-lb

Installing the Cisco MDS 9700 Series Switches

Installation Guidelines

• M6 screws: 20 in-lb

• 12-24 screws: 30 in-lb

• 10-20 screws: 22 in-lb

Attaching Bottom-Support Rails to a Two-Post Rack

The bottom-support rails support the weight of the switch chassis in the rack or cabinet. To maximize the

stability of the rack, you must attach these rails at the lowest possible rack unit (RU).

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:

• This unit should be mounted at the bottom of the rack if it is the only unit in the rack.

• When mounting this unit in a partially filled rack, load the rack from the bottom to the top with the

heaviest component at the bottom of the rack.

• If the rack is provided with stabilizing devices, install the stabilizers before mounting or servicing the

unit in the rack.

Note

Before you begin

Before you can install the bottom support rails for the chassis, you must do the following:

• Verify that a two-post rack is installed and secured to the concrete sub floor (see “Installing a Rack or

Cabinet”).

• If any other devices are stored in the rack or cabinet, verify that they are located below where you plan

to install the switch. Also, verify that lighter devices in the same rack are located above where you plan

to install this switch.

• Verify that the two-post bottom-support rails kit was ordered and shipped with the chassis.

Statement 1006

Step 1 Position one of the two bottom-support rails at the lowest possible RU in the rack or cabinet. Be sure there is at least 9

RU of vertical space above the rails to install the chassis.

Step 2 Use a manual Phillips torque screwdriver to attach the bottom-support rail to the rack using four M6 x 19 mm or 12-24

x 3/4 inch screws and tighten each screw to 40 in. lbs (4.5 N.m) of torque.

Make sure that the two bottom-support rails are level with one another. If they are not level, adjust the higher

rail down to the level of the lower rail.

Note

When the bottom-support rails are installed at the lowest possible RU and are level, you are ready to install the chassis

in the rack or cabinet.

Attaching Bottom-Support Rails to a Four-Post Rack

The bottom-support rails support the weight of the switch chassis in the rack or cabinet. To maximize the

stability of the rack, you must attach these rails at the lowest possible rack unit (RU).

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:

• This unit should be mounted at the bottom of the rack if it is the only unit in the rack.

• When mounting this unit in a partially filled rack, load the rack from the bottom to the top with the
