Note – In some cases, it is possible that the disk tray could time out before it
receives the RARP request through an Ethernet switch. If this happens, the disk tray
cannot receive the assigned IP address. If the disk tray should time out before
receiving the RARP request, it could be due to an improper spanning-tree setting of
the Ethernet switch. Refer to your switch vendor documentation for information on
spanning-tree settings and how to change them. Changing this setting properly will
enable the disk tray to receive the RARP request before timing out.
2.4 Installing the Disk Tray
This section describes the procedures for installing either a single controller unit or
partner group configuration. (See Chapter 1 for an explanation of each
configuration.) There are two types of installation: tabletop placement and
rackmounted in a server cabinet or expansion cabinet.
■
If you are placing the disk tray(s) on a table, proceed to Section 2.4.1 “Tabletop
Placement” on page 2-7.
■
If you are mounting the disk tray(s) in a server cabinet or expansion cabinet,
proceed to Section 2.4.2 “Cabinet Installation” on page 2-8.
2.4.1 Tabletop Placement
The disk tray is designed to sit on a desk or table. Use the following guidelines to
prepare a location for your system.
■
Choose a desk or table that can support up to 67 pounds (30 kg) for one fully
configured disk tray or 135 pounds (60 kg) for two disk trays.
■
Leave enough space in front and in back of the disk tray to access components.
■
Provide a minimum space of 6 inches (15 cm) in front and in back of the disk tray
for adequate air flow.
■
Keep power and interface cables clear of foot traffic. Route cables inside walls,
under the floor, through the ceiling, or in protective channels. Route interface
cables (excluding fiber-optic cables) away from motors and other sources of
magnetic or radio frequency interference.
■
Make sure that the fiber-optic and power cable lengths do not exceed cable length
limitations. See Appendix A for cable lengths.
■
Ensure that the operating environment for the disk tray does not exceed the
specifications. See Appendix A for environmental specifications.
