Mounting Brackets
The JA1500 appliance includes front ears, rear mounting rails for mounting in a 4-post standard rack, and midpoint brackets for mounting in a 2-post, 19-inch equipment rack.
Chassis
The JA1500 appliance has a 2U rack-mountable chassis. The chassis includes the following:
- Three 1TB hard disks in hot-swappable RAID 5 array
- One RAID controller
- Four RJ-45 10/100/1000 Gigabit Ethernet ports
- One RJ-45 serial console port
- One USB interface
- Optional single IOC slot available for I/O card expansion
- One 250-watt cold-swappable power supply with an AC power receptacle; 1 optional dual-redundant, hot-swappable power supply
- One AC power switch
- Two cooling fans
Hard Disks
The JA1500 appliance includes three hard disk drives in RAID 5 array. The serial attached SCSI (SAS), hot-swappable drives are externally accessible in field-replaceable trays, providing component high availablilty. If one drive fails, the system recovers by hot-swapping the failed drive, which is automatically rebuilt. A fourth, empty hard disk tray is available for a spare disk. The disks are labeled from left to right Disk 0 , Disk 1, Disk 2. Front panel LEDs indicate drive activity and failure.
Ports
The JA1500 Appliance includes the following ports:
- Four RJ-45 10/100/1000 Mbps network ports using an Intel Gigabit Ethernet controller. The ports are numbered from left to right: ETH3, ETH2, ETH1, ETH0.
- One RJ-45 serial console port labeled CONSOLE.
- One USB interface
- One optional single input/output card (IOC) slot available for expansion I/O ports. The JA1500 ships with a dummy tray that can be replaced with an upgrade I/O card.
RAID Controller
The JA1500 appliance RAID controller manages the physical disk drives and presents them to the computer as logical units.
Status LEDs
The JA1500 Appliance LEDs are shown in Figure 2.

Cooling System
The JA1500 appliance includes two rear-accessible, hot-swappable fans to cool the other components.
AC Power Switch
The AC power switch is between the fans on the left and the power supplies on the right.
Power Supply
The JA1500 appliance includes a cold-swappable, 250 W (90 to 264 V) autoranging power supply for all countries. The power supply is high efficiency and is 80 PLUS certified. The power supply includes an AC receptacle for a power cord. The JA1500 appliance is upgradable to a redundant hot-swappable dual power supply. The power supplies are numbered from bottom to top: PSU1, PSU2.
If the JA1500 appliance includes two power supplies, plug each power cord into a separate power circuit to ensure that the device continues to receive power if one of the power circuits fails.
