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.

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

You should also have at least two persons to push the chassis when you slide it
onto the rack.
Note
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
Step 1 If you need to make the chassis as light as possible for moving, you can optionally remove the fabric modules, fan
modules, and power supplies.
a) To remove a power supply, follow these steps:
1. Push and hold the release handle on the power supply to the left.
2. Pull the power supply about two inches (about 5 cm) out of the chassis.
3. Place one hand under the power supply to support its weight and pull the power supply out of the chassis.
4. Place the power supply on an antistatic surface.
b) To remove a fan module, follow these steps:
1. Unscrew the four captive screws on the front of the fan module (one captive screw in each corner of the front
of the fan module).
2. Hold both handles on the fan module with both of your hands and pull the fan module out of the chassis.
3. Place the fan module on an antistatic surface.
c) To remove a fabric module, follow these steps:
Before you can remove a fabric module, you must remove the fan module that is installed in front of
it.
Note
1. Press the lever eject button found in the middle of the front of the module.
2. Rotate both of the levers away from the fabric module.
3. When the other end of each lever is no longer holding onto the chassis, pull the two levers to slide the module

4. Rotate the two levers back to the fabric module. Each lever will click when locked in place.
5. Place one hand on the front of the module and place your other hand under the module to support its weight.
6. Slide the module out of the chassis and place the module on an antistatic surface.
Step 2 Load the chassis onto a mechanical lift or floor jack as follows:
a. Position the mechanical lift next to the shipping pallet that holds the chassis.
b. Elevate the lift platform to the level of the bottom of the chassis (or no more than 1/4 inch [0.635 cm] below the
bottom of the chassis).
c. Use two persons to slide the chassis fully onto the lift so that the side of the chassis touches or is close to the vertical
rails on the lift. Make sure that the front and rear of the chassis are unobstructed so you can easily push the chassis
into the rack.
To prevent personal injury or damage to the chassis, never attempt to lift or tilt the chassis using the
handles on modules (such as power supplies, fans, or cards); these types of handles are not designed
to support the weight of the unit. Statement 1032
Warning
To lift the chassis, use a mechanical lift. Do not use the handles on the side of the chassis (the handles
are not rated for lifting over 200 pounds [91 kg]). Use the side handles for only repositioning the chassis
after it is already on the mechanical lift or in the rack or cabinet.
Caution
Step 3 Use the mechanical lift to move and align the rear of the chassis to the front of the rack or cabinet. Make sure that the
bottom of the chassis is elevated to the height of the bottom-support rails or no more than 1/4 inch (0.6 cm) above the
rails.
Step 4 Push the chassis halfway onto the rack or cabinet.
Use two persons to push the chassis onto the bottom-support rails. Push the lower half of the front side of the chassis
so that the back side enters the rack first, and push until the chassis is halfway onto the rack (see the following figure).
Ensure that the chassis does not get caught on any of the expansion edges of the bottom-support rail.

To adjust the placement of the chassis on the bottom-support rails, you can use the handles on the sides of
the chassis.
Tip
Step 5 If the mechanical lift is raised above the height of the bottom-support rails, gently lower it to the level of the rails or
no more than 1/4 inch (0.6 cm) below the rails.
This action helps to prevent the bottom of the chassis from getting caught on the bottom expansion edges of the
bottom-support rails.
Step 6 Push the chassis all the way onto the rack so that the vertical mounting brackets on the chassis come in contact with
the vertical mounting rails on the rack.
Step 7 Use seven M6 x 19 mm or 24 x 3/4-inch screws to attach each of the two vertical mounting brackets on the chassis to
the two vertical mounting rails on the rack (total of 14 screws). See the following figure.

Step 8 Use eight M6 x 10 mm screws to attach the bottom-support rails to the chassis (use a total of 16 screws for both bottom
support rails). See previous image.
Step 9 If you removed any fabric modules before moving the chassis, replace each one in the chassis as follows:
a. Holding the front of the fabric module (the side with the LEDs), turn the module so that the front side is vertical.
The top of the module has an alignment bracket running from the rear to the front. The electrical
connectors will be at the bottom.
Note
b. Align the rear of the fabric module to an open fabric slot and insert the bracket on top of the module into the track
at the top of the slot.
If there are only three fabric modules to install, install them in fabric slots 1, 3, and 5, and be sure that
there are blank filler plates installed in the open slots.
Note
c. Slide the module part way into the slot.
d. Press the ejector button on the front of the module, to release the levers from the front of the module.

e. Rotate the levers away from the front of the module and hold them while sliding the module all the way into the
slot.
f. Simultaneously rotate both levers to the front of the module. They click when locked to the front of the module.
Step 10 If you have removed any fan modules before moving the chassis, reinstall each one in the chassis as follows:
a. Holding each of the two handles on the fan module with your two hands, align the fan module to an open fan module
slot.
The two alignment brackets on top of the fan module should align to two tracks at the top of the slot.
Note
b. Slide the fan module into the slot until the front of the fan module comes in contact with the rear of the chassis.
The two alignment pins on the fan module (on the top and one on the bottom) should go into holes in
the chassis and the four captive screws on the fan module should align to screw holes in the chassis.
Note
c. Screw in the four captive screws to the chassis and tighten each screw to 8 in-lb (0.9 N·m).
Step 11 If you have removed any power supplies before moving the chassis, reinstall each one as follows:
a. Determine which power supply slots to fill and ensure that each of those slots is open.
If you are using the combined or power supply redundancy mode, you can use any slot for the power supply that
you are installing.
If you are using the input-source or full redundancy mode, you must group the power supplies that are to be connected
to the same grid on either the left or right power supply slots in the chassis (that is, place the power supplies for
grid A in slots 1 or 2 or both slots and place the power supplies for grid B in slots 3 or 4 or both slots).
For information on the power supplies supported by Cisco MDS 9700 series switches, see the Power Supply section
under the Product Overview chapter.
b. Place one hand on the front of the power supply and place your other hand under it to support its weight.
c. Align the power supply to an open power supply slot.
The alignment bracket on top of the power supply should align to a track at the top of the slot and a
bar at the bottom of the power supply should be guided by a track at the bottom of the slot.
Note
Step 12 Slide the power supply all the way into the slot until its release handle clicks and the module stops.

The rack stabilizing mechanism must be in place, or the rack must be bolted to
the floor before you slide the unit out for servicing. Failure to stabilize the rack
can cause the rack to tip over. Statement 1048
Warning
• Verify that the bottom-support rails have been attached to the lowest possible RU in the rack or cabinet
and there is 14 RU (24.5 inches [62.2 cm]) of space above the rails to install the chassis.
• For Cisco MDS 9718 chassis, verify that the bottom-support rails have been attached to the lowest
possible RU in the rack or cabinet and there is 25 RU (43.75 inches [111 cm]) of space above the rails
to install the chassis.
• If there are other devices in the rack, verify that the devices that are heavier than this chassis are installed
below where you are going to install the chassis and lighter devices are installed above where you are
going to install the chassis.
• Verify that the data center ground is accessible where you are installing the chassis.
• Verify that you have the following tools and equipment:
• Mechanical lift capable of lifting the full weight of the chassis and its installed modules
If the rack is on wheels, ensure that the brakes are engaged or that the rack is
otherwise stabilized. If connecting a Cisco MDS 9700 Series switch to a 110-VAC
power system, ensure that sufficient power is provided to meet the chassis power
requirements for the number of modules installed.
Caution
All power supplies must be grounded. The receptacles of the AC power cables
used to provide power to the chassis must be the grounding type, and the grounding
conductors should connect to protective earth ground at the service equipment.
For a Cisco MDS 9700 Series switch with a DC power supply, a grounding cable
must be connected to the terminal block.
Caution
When connected to 220 VAC, the 3000-W AC power supplies DS-CAC97-3KW for the Cisco MDS
9700 Series switch are designed to provide an output power of 3000 W to power the modules and
fans. When connected to a 110 VAC power system, the power supply provides approximately 1450
W. In this case, and if the power supplies are used in redundant rather than combined mode, they
might not provide adequate power, depending on the number of modules loaded in the chassis.
If a 110-VAC input is chosen, a 110-VAC power cord (CAB-7513AC=) must be ordered separately.
When installing or replacing the unit, the ground connection must always be made
first and disconnected last. Statement 1046

4. Place the power supply on an antistatic surface.
b) To remove a fan module, follow these steps:
1. Unscrew the four captive screws on the front of the fan module (one captive screw in each corner of the front
of the fan module).
2. Hold both handles on the fan module with both of your hands and pull the fan module out of the chassis.
3. Place the fan module on an antistatic surface.
c) To remove a fabric module, follow these steps:
Before you can remove a fabric module, you must remove the fan module that is installed in front of
it.
Note
1. Press the lever eject button found in the middle of the front of the module.
2. Rotate both of the levers away from the fabric module.
3. When the other end of each lever is no longer holding onto the chassis, pull the two levers to slide the module
a couple inches out of the chassis.
4. Rotate the two levers back to the fabric module. Each lever will click when locked in place.
5. Place one hand on the front of the module and place your other hand under the module to support its weight.
6. Slide the module out of the chassis and place the module on an antistatic surface.
Step 2 Load the chassis onto a mechanical lift or floor jack as follows:
a. Position the mechanical lift next to the shipping pallet that holds the chassis.
b. Elevate the lift platform to the level of the bottom of the chassis (or no more than 1/4 inch [0.635 cm] below the
bottom of the chassis).
c. Use two persons to slide the chassis fully onto the lift so that the side of the chassis touches or is close to the vertical
rails on the lift. Make sure that the front and rear of the chassis are unobstructed so you can easily push the chassis
into the rack.
To prevent personal injury or damage to the chassis, never attempt to lift or tilt the chassis using the
handles on modules (such as power supplies, fans, or cards); these types of handles are not designed
to support the weight of the unit. Statement 1032
Warning
To lift the chassis, use a mechanical lift. Do not use the handles on the side of the chassis (the handles
are not rated for lifting over 200 pounds [91 kg]). Use the side handles for only repositioning the chassis
after it is already on the mechanical lift or in the rack or cabinet.

Step 3 Use the mechanical lift to move and align the rear of the chassis to the front of the rack or cabinet. Make sure that the
bottom of the chassis is elevated to the height of the bottom-support rails or no more than 1/4 inch (0.6 cm) above the
rails.
The Cisco MDS 9700 Series switch has the front-to-back cold-aisle and hot-aisle air flow design. We
recommend that you maintain a minimum air space of 7 inches (30.5 cm) at the chassis front and back air
vents.
Note
Step 4 Push the chassis halfway onto the rack or cabinet.
