Rack Chassis Options

SL Optic units can be deployed as standalone devices with individual power supplies, or consolidated into a 19" rack chassis for a tidier, higher-density installation. Two chassis models are available, covering both a budget-friendly and a fully redundant power scheme.

Renders and photos are for illustration only

Some images on this page show the chassis with a demonstration device or blank filler panels installed instead of SL Optic — this is intentional and illustrates chassis compatibility and mechanical fit only. Refer to Hardware for the actual appearance and controls of SL Optic itself.

Overview

Model Best for Power scheme
SL RackHub 3S Simple consolidation, lowest cost Individual PSUs per unit (existing PWR A/PWR B)
SL RackHub 3R Mission-critical deployments Shared dual hot-swap PSUs with N+1 redundancy

Both models are 1U 19" rack chassis and hold up to three SL Optic units side by side.

SL RackHub 3S

The SL RackHub 3S is a simple 3-slot mounting tray. Each bay holds one SL Optic unit, and every unit is powered exactly as it would be on a desktop — through its own PWR A and PWR B connectors on the rear panel. The chassis itself supplies no power; it only provides rack mounting and cable management for up to three units.

Key features

  • Three independent 19" mounting bays in 1U
  • No internal electronics — purely mechanical, nothing to fail
  • Each unit keeps its individual PWR A / PWR B redundant power inputs
  • Units can be added, removed, or serviced without affecting neighboring bays
  • Lowest-cost path to rack-mounting SL Optic

Power requirements

Because each bay powers its unit independently, the number of external PSUs needed depends on the redundancy level you choose per unit:

Configuration PSUs required
1 unit, no redundancy 1
1 unit, redundant 2
3 units, no redundancy 3
3 units, fully redundant 6

See Power for PSU connection details.

SL RackHub 3R

The SL RackHub 3R replaces individual external power supplies with a shared, redundant power backplane. Two hot-swappable 350 W PSU modules feed all three bays over an internal backplane; each installed unit connects directly to the backplane through its internal card-edge connector, in addition to its standard PWR A / PWR B connectors (unused in this configuration). If one PSU module fails, the remaining module continues to power all three bays without interruption.

Key features

  • Two hot-swappable 350 W PSU modules, N+1 redundant
  • Single shared backplane powers all three bays — no per-unit PSU cabling
  • Units connect via internal card-edge contact; standard PWR A/PWR B ports remain available but are not used in this configuration
  • PSU modules can be replaced without powering down the chassis or removing installed units
  • Independent IEC C14 inlet per PSU module — connect each to a separate circuit or UPS for full redundancy

Power redundancy depends on separate circuits

Connect each PSU module to an independent power source (separate circuit or UPS). Powering both modules from the same source removes the redundancy benefit.
