IBM TotalStorage FAStT EXP700, Installation And User Manual

Page: 27 / 100

more FAStT EXP700 expansion units together. Install an SFP module into the
input and output ports. Fibre Channel cables are used to connect the expansion
unit to the controller or to additional expansion units.
v
ESM latch: The ESM latch secures the ESM to the expansion unit.
v
ESM levers: The ESM latch must be unlocked before you can use the ESM
levers to remove the ESM from the expansion unit. When you are installing the
ESM into the bay, use the ESM levers to guide the unit into the ESM bay.
v
ESMs: The ESMs contain the expansion unit controls, switches, and LEDs. Each
ESM has two SFP module ports for connecting the expansion unit to the
controller.
v
Fault LED: The amber ESM fault LED is lit when an ESM failure occurs.
v
Input/output bypass LEDs: These amber LEDs are lit when a faulty SFP
module or fiber-optic cable is installed. Both ports on the ESM are bypassed and
the LEDs are lit in the event of an ESM fault. In this case, the ESM fault error
LED is also lit. This LED is also lit if an SFP module is installed and not
connected to another device.
v
Power LED: The green power LED is lit when there is power to the ESM.
v
Over-temperature LED: The ESM amber LED is lit if the expansion unit
overheats.
v
Enclosure ID switches: Two enclosure ID switches are located between the
power supplies at the rear of the FAStT EXP700. These switches are used to
identify the FAStT EXP700 on a Fibre Channel loop and to assign physical
addresses to the drives. You can use the push buttons to set the values between
0 and 7. The X1 value assigns the physical addresses of the drives and the
ESM. The X10 value identifies the loop where the FAStT EXP700 is located.
v
1 Gb/s 2 Gb/s switch: Use the 1 Gb/s 2 Gb/s switch located on the back of the
FAStT EXP700 to enable drive operation. The default setting is 2 Gb per second.
Your switch setting will depend on your system configuration.
Note: To determine which speed the expansion unit must be set to, see Table 1.
Storage-management software and hardware compatibility
Table 1 lists the FAStT EXP700 hardware and software compatibility and the
maximum speed that the FAStT EXP700 can be set to when configured with other
IBM FAStT hardware and software products.
