Four-Shelf and Zero-Shelf Bay Assembly
Overview
The Cisco ONS 15454 Four-Shelf and Zero-Shelf Bay Assemblies provide a dual-feed pre-wired
TPA-type Fuse and Alarm Panel, two vertical fiber ducts, and two 2.38-inch vertical extenders and
extender bases. The Four-Shelf Bay Assembly also provides a pre-installed, four-shelf configuration that
includes four ONS 15454 shelf assemblies with configured backplane interface connectors (BICs).
This guide describes how to unpack and install the Cisco ONS 15454 Four-Shelf and Zero-Shelf Bay
Assembly. Because it is a complete system, installation simply requires you to remove the unit from the
shipping pallet, move the unit into place, secure it, supply power and ground attachment.

Safety Recommendations
Safety Recommendations
The following guidelines will help to ensure your safety and protect the equipment. This list does not
include every potentially hazardous situation.
•Never attempt to lift an object that might be too heavy for you to lift by yourself.
•Always disconnect the power source and unplug all power cables before installing or removing the
Bay Assembly.
•Carefully examine your work area for possible hazards such as moist floors, ungrounded power
extension cables, and missing power grounds.
•When using equipment such as a safety hand truck, pallet jack, or forklift to move the Bay Assembly
to another location, use only moving equipment that is capable of preventing the Bay Assembly from
tipping.
•Do not wear loose clothing, jewelry (including rings and chains), or other items that could get caught
in the Bay Assembly.
•Do not work alone if potentially hazardous conditions exist.
Recommended Materials
Because most of the installation is complete when you receive the system, the Bay Assembly requires
little installation material. The most significant tasks are removing the packaging from the Bay
Assembly and removing the Bay Assembly from the shipping pallet. Because the actual installation of
the Bay Assembly in each facility is done according to local site practice, your material needs may vary.
Cisco recommends that you have the following items on hand for installation:
•A pallet jack to move the packaged Bay Assembly to the unpacking/staging area
•A pair of scissors to cut the plastic banding on the shipping container
•A safety hand truck with retractable safety leg wheels and a safety strap
•Utility blankets or their equivalent to protect the Bay Assembly while on the hand truck
•Phillips screw driver or cordless drill with Phillips bit
•3/4 in. (19 mm) socket or box-end wrench for the earthquake floor bolts
•Four optional kits listed in Table 2 on page 33 that can be ordered separately

Installation Instructions
Installation Instructions
The emphasis in the following installation instructions is to remove the Bay Assembly from its shipping
pallet and position it in your facility. Perform actual installation and individual node provisioning
according to local site practice.
Install the Four-Shelf and Zero-Shelf Bay Assembly
Step 1 Line the hand truck with a utility blanket or an equivalent type of protection.
Step 2 Position the safety hand truck so that it faces the front (door side) of the Bay Assembly.
Step 3 With one person on each side of the Bay Assembly and one manning the hand truck, position the blade
of the hand truck under the edge of the rack.
Step 4 Secure the safety strap snugly around the Bay Assembly.
Do not cinch the strap too tightly. Cinching the strap too tightly can result in component damage.
Step 5 Extend the outrigger wheels from the hand truck.
Step 6 With one person on each side of the Bay Assembly, gently tilt the Bay Assembly until the outrigger
wheels on the safety hand truck are firmly on the floor.
Step 7 Move the Bay Assembly to the installation site and unload it from the safety hand truck.
To avoid injury, make sure that a sufficient number of people are present.
Step 8 Install the Bay Assembly according to local site practice.
For more information about installing or configuring individual Cisco ONS 15454s, refer to
Cisco ONS 15454 user documentation.
Step 9 After the rack is installed attach the extender bases and vertical extenders to both sides of the rack.
a. Attach the two extender bases to each side of the rack using the hardware supplied with the extender
bases.
b. Attach the two vertical extenders to each side of the rack using the hardware supplied with the
vertical extenders.

Installation Instructions
Raised Floor Plan
Level Equipment
The raised floor is laser-leveled at the time of the floor installation, so no leveling blocks or shims should
be necessary to level the frames. This is especially important in seismic zones 2B and higher, because
leveling blocks will cause a rocking motion of the frames during an earthquake.
Cut and Drill Removable Floor Tile
Step 1 Mark the removable floor tile for the cable access to the rack using one of the following methods: the
floor cutout template included in the accessory kit (700-14208-XX) that ships with the zero-shelf bay
assembly, the diagrams in Figure 6, a floor plan drawing, or place the frame in the proper footprint and
mark the tile from the base of the frame or cabinet.
Step 2 Mark the tile for the frame anchoring holes.
Step 3 Remove the tile.
Step 4 Cut cable access holes.
Step 5 Drill the anchoring holes through the tile in an area away from the equipment to ensure the equipment
area is not contaminated with metal shavings or debris.
Note If the floor plan identifies a future frame on the same tile as the one you are adding a frame to,
you must drill and cut the tile for the future frame at this time because you cannot remove the
tile later.
Note It will be necessary to use alternate anchoring holes in the event the primary holes are obstructed
by the stringers that support the removable tile.

Framework Anchoring
To anchor framework to a raised floor, you must know in what earthquake zone the equipment is being
installed. Zones 0–2A have the frames bolted to the raised floor through a u-channel across the bottom
of the floor tile and stringers. Zones 2B–4 have 1/2-inch threaded rods extending through the raised floor
and connected to seismic anchors with coupling nuts. In all zones, standard hold-down parts are used on
top of the floor with threaded rods of varying lengths. Anchors and hold-down material must be
engineered for proper seismic zone.
Seismic Zones 0–2A
To fasten network and unequal flange duct framework to a raised floor:
Step 1 Place a 1 5/8 x 1 5/8 u-channel (with continuous slot down) under the stringers and use clips to cover
the free ends of the u-channel where the threaded rod goes through to prevent it from spreading when
compressed.
In the base of the frame, use the hold-down plate engineered for that frame, threaded rod, nut, washer,
insulating bushing, and hold-down washer.
On the bottom of the u-channel, use the clip, washer, lockwasher, and nut.
Note The u-channel should not extend more than four inches past the edge of the stringers or it will block
access under the floor.

Installation Instructions
Warning End caps must be used on the u-channel to prevent injury.
Step 2 Torque the nut to 30 ft-lbs.
Note Do not over tighten the nut; the tile will become deformed and will be uneven with surrounding tiles.
Seismic Zones 2B–4
In seismic zones 2B and higher, threaded rods are run down to seismic anchors with coupling nuts from
the concrete floor. U-channels are not used in higher earthquake zones. Anchor the rack at all four
corners in higher earthquake zones.
Note Do not over tighten threaded rods; floor tile will deform and make the floor uneven.
Route Fiber Through the Base
Step 1 After installing the rack onto the raised floor, remove the base plate cover from the rack by removing
the screws on the front of the base plate, as shown in Figure 7.

Installation Instructions
Step 2 To route fiber, remove the two top covers on the base plate or extender base by unscrewing the two
screws on the covers, as shown in Figure 8.
Figure 8 Base plate with two top covers removed
When the covers have been removed, you have access to the base of the rack and any holes previously
cut into the raised floor tile, as shown in Figure 9.
Figure 9 Raised floor base fiber routing close-up
You can use the base plate or extender base holes to route the fibers. Cisco recommends using the base
plate holes for the bottom node and the extender base holes for the other three nodes on the four-node
rack.
All electrical cables will be routed in the back of the rack in the extender bases. Holes should already be
cut out in the raised floor tile to compensate for any DS1, DS3, ground and power cables.

Step 3 Once all fiber cables have been placed in the front portion of the rack, replace the base plate cover by
sliding the cover toward the back of the rack and replacing the screws that hold the covers. Figure 10
shows the routed fiber with the base plate cover replaced.

Mounting a Single Shelf Assembly
Mounting a single ONS 15454 in a rack requires a minimum of 18.5 inches of vertical rack space (plus
1 inch for air flow). To ensure the mounting is secure, use two to four #12-24 mounting screws for each
side of the shelf assembly. Figure 11 shows the rack mounting position for the ONS 15454.

Figure 11 Mounting a single ONS 15454 in a rack
Two people should install the shelf assembly; however, one person can install it using the temporary set
screws included. The shelf assembly should be empty for easier lifting. The door can also be removed
to lighten the shelf assembly.
Note If you are installing the fan-tray air filter using the brackets provided, mount the brackets on the bottom
of the shelf assembly before installing the ONS 15454 in a rack.
Mount the Shelf Assembly in a Rack (One Person)
Step 1 Ensure that the shelf assembly is set for the desired rack size (23 inches).
Step 2 Install the set screws using the hex tool that ships with the shelf assembly. Use the screw holes that will
not be used to mount the shelf.
Step 3 Place the shelf assembly on the set screws.
Step 4 Lift the shelf assembly to the desired rack position.
Step 5 Align the screw holes on the mounting ears with the mounting holes in the rack.
Step 6 Install one mounting screw in each side of the shelf assembly.
One or more sets of the horizontal screw slots on the ONS 15454 should be used to prevent future
slippage.
Step 7 When the shelf assembly is secured to the rack, install the remaining mounting screws.
Step 8 Remove the temporary set screws.
