Handling precautions/Electrostatic discharge protection

Disc drives are fragile. Do not drop or jar the drive and handle the drive only by the edges or frame.

Drive electronics are extremely sensitive to static electricity. Keep the drive in its antistatic container until you are ready to install it. Wear a wrist strap and cable connected to ground. Discharge static from all items near or that will contact the drive. Never use an ohmmeter on any circuit boards.

Turn off the power to the host system during installation.

Always use forced-air ventilation when operating the drive.

Use caution when troubleshooting a unit that has voltages present.

Do not disassemble the drive; doing so voids the warranty.

Return the entire drive for depot service if any part is defective.

Do not apply pressure or attach labels to circuit board or drive top.

Installation instructions

1. Mount the drive in the host system carrier or tray

Most Fibre Channel host systems (including enclosures) provide a way to insert the drive using a carrier or tray which allows the drive to be hot- plugged into the system’s Fibre Channel 40-pin single connector attach- ment (FC-SCA).

Mount the drive to the carrier or tray provided by the host system using four 6-32 UNC screws. Two mounting holes are in each side of the drive and there are four mounting holes in the bottom of the drive. Do not over-tighten or force the screws. You can mount the drive in any orientation. See Figure 1.

Note. FC and FCV drives are designed to be attached to the host system without I/O or power cables.

Figure 1. Sample drive carrier

2. Insert the drive

Slide the carrier or tray into the appropriate bay in your host system. This connects the drive directly to your system’s 40-pin Fibre Channel single connector attachment (FC-SCA). The FC-SCA connector is normally located on a Fibre Channel backpanel.

Note. There are no jumpers or terminators on the drive, and power is sup- plied through the 40-pin connector.

3. Connect LEDs (optional)

Note. This is an optional step. The drive will work fine without the LEDs connected to the drive.

The drive supplies pins that you can use to connect fault and active LEDs. This allows you to monitor drive fault conditions and activity. The actual LED is external to the drive.

[1]The drive has a 2.2K ohm resistor in series with this LED driver. Tie the minus side of an external high-efficiency LED (i.e., 2ma) to this pin. Connect the plus side of the LED to +5V.

[2]An external current-limiting resistor is required when connecting an LED to this pin. The minus side of the resistor/LED combination is con- nected to this pin. Connect the plus side to +5V.

ST1181677FC, ST1181677FCV specifications

The Seagate ST1181677FCV and ST1181677FC are part of Seagate's line of high-capacity storage solutions, designed specifically for enterprise environments that require robust performance and reliability. These hard disk drives (HDDs) are notable for their large capacities, advanced technologies, and features that cater to the demanding needs of data centers and enterprise applications.

One of the primary features of the ST1181677FCV and ST1181677FC is their impressive storage capacity. With 180GB of space available, these drives provide ample room for critical data, applications, and virtual machines. This large capacity is essential for organizations that rely on data-intensive operations and require scalable storage solutions to accommodate growing data workloads.

Both models utilize Fast Adaptive Read-Write Technology, which enhances performance by optimizing data access times and improving throughput. This technology enables the drives to handle multiple read and write operations efficiently, making them suitable for environments that handle numerous concurrent users and tasks. This is particularly beneficial in transactional systems, databases, and in applications that demand low latency.

In addition to performance, reliability is critical for enterprise storage. The ST1181677FCV and ST1181677FC are designed with advanced error-correction and redundancy features to minimize data loss and ensure data integrity. These drives are equipped with features like rotational vibration (RV) tolerance, which helps maintain performance in multi-drive systems by mitigating the effects of vibration that can occur in densely populated storage environments.

The drives also utilize a Serial Attached SCSI (SAS) interface, which provides a high-speed connection to servers and storage systems, enabling faster data transfer rates compared to traditional ATA interfaces. This makes them ideal for enterprise-level applications where speed and efficiency are paramount.

Another notable characteristic of the ST1181677FCV and ST1181677FC is their commitment to energy efficiency. These drives are designed to consume less power, which not only reduces operational costs but also contributes to a lower carbon footprint for organizations seeking to improve their sustainability practices.

In summary, the Seagate ST1181677FCV and ST1181677FC represent a powerful combination of high capacity, advanced technologies, and robust reliability. With features designed to meet the demands of enterprise environments, these HDDs are a solid choice for organizations looking to implement scalable storage solutions without compromising performance.
