Cisco ONS 15454 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 electrical interface assembly (EIA) panels or EIA blank cover panels.
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, and supply power and ground attachment. Refer to
the Cisco ONS 15454 user documentation for component-specific installation and replacement
procedures. Figure 1 on page 2 shows a four-shelf bay assembly.

Recommended Material
Recommended Material
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 forklift or 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
•Utility blankets or their equivalent to protect the bay assembly while on the forklift or pallet jack
•Phillips screw driver or cordless drill with Phillips bit
•3/4 inch socket or box-end wrench for the earthquake floor bolts
•Four optional kits listed in Table 3 on page 33 that can be ordered separately
•Use this guide in conjunction with Cisco ONS 15454 documentation (procedure guide,
troubleshooting guide and reference manual), and the latest release of the
Cisco ONS 15454-FAP-LVD Operations Guide.
Unpacking Instructions
The ONS 15454 four-shelf and zero-self bay assembly ships in a corrugated container that covers the
rack on its shipping pallet. After removing the corrugated container, you must remove the bolts that hold
the rack to the pallet before moving the unit to the desired location. Figure 3 shows the four-shelf bay
assembly on a shipping pallet.
Caution Cisco recommends that a minimum of three people move the bay assembly.
Step 1 Use a forklift or pallet jack to place the shipping container as close to the installation location as
possible.
Step 2 Cut the plastic banding off of the cardboard shipping container.
Step 3 Remove the cap from the corrugated container.
Step 4 Pull the side panels away from the shipping pallet and set it aside.
Step 5 Remove the base plate from the bottom front of the rack:
a. Remove the two screws that fasten the base plate to the rack.
b. Pull the base plate away.
Step 6 Remove the four bolts that hold the rack to the pallet (rack base bolts).
Step 7 Remove the vertical extenders if necessary.

Installation Instructions
Installation Instructions
Prior to installing the bay assembly, you should prepare your slab or raised floor plan.
Slab Floor Plan
Level Equipment
Temporarily position and level using metal shims and the equipment frame.
Drill Slab Floor
Step 1 Mark the slab floor for the anchoring holes using either the provided template or by positioning the rack
in the desired location. Figure 4 on page 8 shows a rack cross section with cabling routes. Figure 5 on
page 8 shows fiber routing for a slab base. After the floor marks have been made, move the template or
rack aside.
Step 2 Drill the anchoring holes into the slab using a masonry drill bit. Make sure the masonry dust is removed
from the holes.
Step 3 Reposition the rack over the holes. Depending on the type of slab floor mounting hardware used, the
anchors may need to be inserted into the holes before the rack is repositioned.
Step 4 Relevel the rack using metal shims if necessary.
Step 5 Install the bay assembly according to local site practice.

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 (700-14208-XX) included in the accessory kit 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. Continue with the procedures in the “Framework
Anchoring” section on page 10.
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.

Figure 6 Raised Floor Cutout for CORE and Local
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.
Install the ONS 15454 Four-Shelf or Zero-Shelf Bay Assembly
The emphasis in the following installation instructions is to position the bay assembly in your facility
after it has been removed from its shipping pallet. Perform actual installation and individual node
provisioning according to local site practice.
Step 1 Use a utility blanket or its equivalent to protect the bay assembly while on the forklift or pallet jack.
Step 2 Position the forklift or pallet jack so that it faces the front (door side) of the bay assembly.
Step 3 With one person on each side of the bay assembly, position the forklift or pallet jack under the rack.
Step 4 If a safety strap is used to secure the bay assembly, fit 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 Move the bay assembly to the installation site and unload it. To avoid injury, make sure that a sufficient
number of people are present.
Step 6 Install the bay assembly according to local site practice.
Step 7 After the rack is installed attach the extender bases and vertical extenders to both sides of the rack as
needed.

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 by sliding
it toward the back of the rack. Figure 10 shows the routed fiber with the base plate replaced.
