B-LINE SB5779140YZ – Frequently Asked Questions
1) Is the B-Line SB5779140YZ rack rated for a Seismic Zone 4 installation?
Yes. The SB5779140YZ is built as a Seismic Zone 4 network bay closed duct rack, so it is the version to specify where your structural drawings call for Zone 4 anchorage. It is also UL Listed. Note that seismic performance depends on anchoring the frame to the slab per the approved detail; the rack itself is the Zone 4 rated component.
2) Do I need to tap the rails, or does this B-Line rack come with threaded 12-24 holes?
The rails come with 12-24 panel mounting holes already, so standard 12-24 rack screws go straight in. Equipment supplied with 10-32 screws will not thread into it, and cage nut style square hole gear will not either. Order 12-24 hardware for your patch panels and shelves.
3) What are the dimensions and weight of the SB5779140YZ rack for planning the room and the freight?
The frame measures 140 in height, 140 in length/depth and 23 in width, and weighs 137 lb. At 140 inches it needs clear vertical space in the room, and at 137 lb it is a two-person set and stand, not a one-man lift.
4) What does the top channel style on the SB5779140YZ mean for my overhead cable runway?
Top channel construction puts a channel across the top of the frame, which is the mounting surface used to tie the rack into overhead cable runway and to brace bay to bay in a lineup. On a 75 space network bay that top connection is how the frame gets its upper support, so the runway or wall bracing has to be in place as part of the install.
5) Is the SB5779140YZ an enclosed cabinet or an open frame rack?
Open frame. There are no side panels, doors or lockable enclosure with the SB5779140YZ, which is why it is a closed duct network bay rather than a cabinet. If the equipment needs physical security or dust control, an enclosed cabinet is the right product instead.
6) Is the yellow zinc finish on this B-Line rack suitable for a data room, or should I look at a painted rack?
Yellow zinc over steel is a plated finish, chosen for corrosion resistance and for a continuous conductive path through the frame rather than for looks. In an equipment room or telecom closet that is normal. If the rack sits in a finished, customer-visible space, a painted black frame is the usual aesthetic choice.
7) What is the exact part number to order this Eaton B-Line seismic network bay rack?
Order it as B-Line SB5779140YZ, the Eaton B-Line series open frame rack in yellow zinc with 75 mounting spaces and 12-24 rails. The YZ at the end of the number is the yellow zinc finish designator.
