B-LINE SB5853090TG – Frequently Asked Questions
1) Will the B-Line SB5853090TG rack meet a Seismic Zone 4 requirement for a telecom room?
Yes. The SB5853090TG is built as a Seismic Zone 4 network bay closed duct rack, so it is the right choice where the structural spec calls for Zone 4 seismic rating. It is also UL Listed. Anchoring to the slab per the engineer's detail is still required, as with any seismic-rated bay.
2) How many rack units of equipment can I mount in this 90 inch B-Line network bay?
The bay gives 38 mounting spaces across a 90 inch overall height. That is usable panel space for 38U of patch panels, switches, or shelves, provided your gear uses standard 19 inch rack mounting.
3) Are the rails tapped 12-24 or do I need cage nuts and 10-32 screws?
The rails come with 12-24 panel mounting holes, so you fasten equipment directly with 12-24 rack screws. No cage nuts or square-hole hardware are involved. If your patch panels and switch ears were bagged with 10-32 screws, order 12-24 screws for this bay.
4) How much floor space do I need for this Eaton B-Line open frame rack?
Footprint planning comes off three numbers: 19 in width, 90 in depth listed for length/depth, and 90 in height. Add your own service clearance front and rear for cable dressing and equipment pulls, since an open frame bay is worked from both sides.
5) Should I use an open frame rack like this or a fully enclosed cabinet?
An open frame bay like the SB5853090TG is for controlled telecom and network rooms where you want full access to both sides of the equipment and the easiest cable management. It gives no physical security or dust protection, so if the gear sits in a shared space, a mixed-use area, or anywhere the public can reach it, go with an enclosed locking cabinet instead. The closed duct top channel design on this one is aimed at routing cable through the bay top rather than at enclosing the equipment.
6) What does the closed duct, top channel style on this B-Line bay do for cable routing?
The top channel carries a closed duct across the top of the bay, which is how cable is brought in and distributed to the mounting spaces rather than draped over open rails. It is the pattern used when bays are ganged in a row under ladder rack, so the duct runs continue from bay to bay.
7) Is this rack steel, and what is the finish for a telecom room?
Construction is steel with a Telco gray powder coat, the standard finish for central office and telecom equipment rooms, so it matches existing Telco gray bays and ladder rack in the same room.
8) How heavy is the SB5853090TG rack to move and set in place?
The bay weighs 77.91 lb. At 90 inches tall that is a two-person carry and stand-up, and it needs to be anchored before any equipment is loaded.
