Chapter 4: Subsystem Connection and Operation Chapter 4 Subsystem Connection and Operation 4.1 FC Host Connection Prerequisites NOTE: The topics covered in Section 4.2 only pertain to the FC models. 4.1.1 Cabling The FC Standard allows for optical connections. Optical cables can be used over long distances, have been shown to be more reliable, and are less susceptible to EMI. Due to the extremely high data transfer rates, optical cables are preferred for 2Gbps FC connectivity.
Galaxy A16F-G2221 Installation and Hardware Reference Manual Safety features: Due to their high power output, OFC lasers usually come with a safety mechanism that switches the laser off as soon as it is unplugged. Non-OFC lasers are low power and do not come with these safety features; however, they can still inflict damage. 4.1.3 SFP Transceivers On the subsystem’s host ports, electric signals are converted by SFP transceivers into laser light pulses.
Chapter 4: Subsystem Connection and Operation 4.1.5 Points of Failure The primary concern for configuring host-side topologies is that points of failure are avoided. It is therefore recommended that the host side be connected to at least two (2) HBAs. By-pass circuitry should be provided outside the subsystem; therefore, it is also preferable to connect the FC RAID subsystems to the host computer(s) through either a FC-2G hub or a Fibre switch.
Galaxy A16F-G2221 Installation and Hardware Reference Manual NOTE: To create dual-redundant data paths on the host side, it is necessary for third-party failover software to be installed on the host computer. 4.1.7 Sample Topology – Direct-Attached In the configuration shown in Figure 4 - 2, one (1) A16F-G2221 subsystem is connected to a single host computer. Data path redundancy makes sense when the following configurations are available: 1. HA access software control is available. 2.
Chapter 4: Subsystem Connection and Operation 4.2 Power On Once all the components have been installed in the Galaxy subsystem, the host channels have been connected to the host, power on the cascaded JBOD(s), the subsystem, the FC hub or switch, and then power on the host computer(s). 4.2.1 Check List BEFORE powering on the Galaxy subsystem, please check the following: Memory Modules – Memory modules have been correctly installed on the controller boards.
Galaxy A16F-G2221 Installation and Hardware Reference Manual The host computers should be the last devices that are turned on. Please refer to the manual that came with your host computers to see their own power on procedures. 4.2.3 Power On Enclosure To power on the subsystem, turn on the two power switches located on the rear panel of the subsystem. (See Figure 4 - 3) Each switch controls a single PSU, therefore make sure that both switches are turned on.
Chapter 4: Subsystem Connection and Operation Audible Alarm - If any errors occur during the initialization process, the onboard alarm will sound in a hastily repeated manner. Drive tray LEDs should normally start flashing, indicating the RAID control units are attempting to access the hard drives. NOTE: The subsystem has been designed to run continuously. Even if a component failure occurs the fault can be corrected online. 4.2.
Galaxy A16F-G2221 Installation and Hardware Reference Manual 4.3 Power Off Procedure To power down the Galaxy subsystem, please follow these steps: NOTE: When powering down the Galaxy subsystem, please ensure that no time-consuming processes, like a “Logical Drive Parity Regeneration” or a “Media Scan,” are taking place. 1. Stop I/O access to the system. Stop all I/O accesses to the Galaxy subsystem. Please refer to the related documentation for your applications. 2. Flush the cache.

Appendix A:Uninterruptible Power Supply Appendix A Uninterruptible Power Supply A.1. Uninterruptible Power Supply Overview An uninterruptible power supply (UPS) is a separately purchased battery backup unit that is connected to an Galaxy subsystem. If the UPS is sufficiently large, it can be used to power the whole subsystem in the event of an AC power failure. A.2. Compatible UPS Supplies The APC SMART-UPS 700VA is compatible with the Galaxy subsystems. A.3.
Galaxy A16F-G2221 Installation and Hardware Reference Manual A.4. Connecting the UPS to the Subsystem A.4.1 Connect the PSU Module Power Cords The two (2) power cables shipped with the subsystem must be plugged into the power cord sockets in the rear of the PSU modules. The plug at the other end of the power cable must be inserted into a socket on the UPS. (See Figure A-2) Please refer to the UPS manual to determine the location of these sockets. The UPS must then be connected to main power. A.4.
Appendix A:Uninterruptible Power Supply A.5. Power On When powering on the subsystem, the UPS must be powered on before the subsystem. To see how to power on the UPS, please refer to the documentation that came with your UPS. Note that the power on sequence described in Chapter 4 will be altered. The power on sequence when a UPS is connected is shown below: Step 1. Power on Fibre Channel connection devices (including hubs and switches). Step 2. Power on the UPS. Step 3. Power on the A16F-G2221 subsystem.
