The J4615 has the highest storage capacity of all of our chassis, and is only 22.75" deep to fit easily into 24" deep rack enclosures. Maximum storage is achieved with nine 5.25" bays, for up to fifteen removable drives! All nine bays can accomodate large removable drive carriers — even ones with built-in fans — just over 10" deep. Plus, with a dedicated slimline optical drive bay, you can fill the bays to capacity and still have a DVD±R drive on the front panel. Mounting is also included for two internal hard drives(*1).

Ease of Assembly:

Two large 12cm fans(*2) are mounted mid-chassis on a drop-in baffle for efficient and effective cooling, eliminating recirculation. Soft foam strips along the top and bottom easily seal around cabling by simply sliding the baffle down into place. The drive bays also slide into place, and the entire assembly locks securely to the chassis with just four screws. A series of spring guides between bays also aid assembly, holding single and multi-bay drive carriers in line. In addition, all nine bays can be inserted individually, allowing a single device to be swapped out without removing the entire assembly.

Server-Class Features:

Inside, the chassis supports ATX form factor system boards (12.0" x 9.6"), and up to seven full-height, full-length PCI cards(*3). Each card slot has fully adjustable card retainers to secure add-on cards of any height. Quickly monitor the system health with four status LEDs on the front panel. Maintain uptime with a redundant, hot-swap power supply up to 10.5" deep. Also included is an adapter to support standard PS/2 form factor PSUs.

Adaptable IO:

On the front panel is an illuminated ATX pushbutton, two USB ports, and a removable logo panel for silkscreened artwork or custom front I/O. On the rear panel are seven PCI card slots, plus two extra PCI brackets and two customizable panels for additional I/O.

(1) Includes bracket for two drives. Up to four internal drives can be mounted with an additional support bracket.

(2) A third 12cm fan can also be mounted to the baffle.

(3) When full-length cards, or cards longer than 11" long are used, the first three 5.25" drive bays will be 8.5" deep.

(4) Two blank panels are included. Additional blank panels, 3.5" bay adapters, and removable drive carriers are available.
