QXS-456 Chassis Overview

The following applies to Xcellis Workflow Director (R630) systems.

The QXS 4U drive chassis includes a bezel sub-assembly that attaches to the front panel of the chassis. The bezel, comprised of a vented cover attached to an electro-magnetic interference (EMI) shield, is pre-assembled and packed within a box contained in the chassis master shipping container. The bezel might include a removable air filter that can be serviced or replaced. Instructions for attaching/removing the bezel, and for servicing or replacing the air filter, are provided in the QX and QXS Bezel Installation Guide.

Note: To access the drawers, you must remove the chassis bezel. Figure 3 shows the chassis with the bezel removed and no rails installed.

Drawer 0 is on the left of the Chassis and Drawer 1 is on the right (Figure 2).

The diagram (Figure 3) and table below display and identify important component items that comprise the rear panel layout of a 56 drive RAID Chassis.

1. Controller I/O module A (see face plate detail figure)
2. Controller I/O module B (see face plate detail figure)
3. AC power supply switch
4. AC power supply (PSU)
5. Fan control module (FCM)

A RAID chassis accommodates the following (Figure 3):

Two controller modules of the same type within the Controller I/O Module slots (see callouts 1 and 2)

Two AC power supplies (CRU) are located within the two power supply slots (Callout 4)

Separate power supply switches (Callout 3)

Two fan control modules (Callout 5)

Caution: All 56 drive configurations are dual-controller. Single-controller support is provided only when a controller fails over to its partner controller. A controller module must be installed in each Controller I/O Module slot to ensure sufficient airflow through the chassis during operation.

Note: The 56 Drive Chassis supports hot-plug replacement of redundant controller modules, fans, power supplies, and expansion modules. Hot-add replacement of drive chassis is also supported.

The following figure shows CNC ports configured with SFP+ transceivers that support 4, 8, or 16 Gb FC, or 10 GbE iSCSI connections. The SFPs look identical. Refer to the CNC LEDs that apply to the specific configuration of your CNC ports.

An expansion chassis accommodates the following (Figure 3):

Two expansion I/O modules of the same type within the Expansion I/O Module slots (see callouts 1 and 2)

Two AC power supplies (CRU)— within the two power supply slots (see two instances of callout 4)

Separate power supply switches (see two instances of callout 3)

Two fan control modules (see two instances of callout 5)

Caution: An expansion I/O module must be installed in each Expansion I/O Module slot to ensure sufficient airflow through the chassis during operation.

Note: The 56 drive Expansion Chassis support hot-plug replacement of redundant I/O modules, fans, and power supplies. Hot-add replacement of entire Drive Chassis is also supported.
