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.

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 forklift or pallet jack 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 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.

Warning

Stability hazard. 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.

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.
