Attention: These notices indicate possible damage to programs, devices, or data.
An attention notice appears before the instruction or the situation in which damage
might occur.
Note: These notices provide important tips, guidance, or advice.
Use the reference numbers in parentheses, for example (1), at the end of each
notice to find the matching translated notice. For all danger, caution, and attention
notices, see the IBM System Safety Notices.
Inspecting the SAN Volume Controller for unsafe conditions
Use caution when working in any potential safety hazardous situation that is not
covered in the safety checks. If unsafe conditions are present, determine how
serious the hazards are and whether you can continue before you correct the
problem.
Before you start the safety inspection, make sure the power is off, and the power
cord is disconnected.
Each machine has required safety items installed to protect users and service
personnel from injury. This guide addresses only those items.
Important: Good judgment must also be used to identify potential safety hazards
due to attachment of non-IBM features or options not covered by this
inspection guide.
If any unsafe conditions are present, you must determine how serious the apparent
hazard could be and whether you can continue without first correcting the
problem. For example, consider the following conditions and their potential safety
hazards:
Electrical hazards (especially primary power)
Primary voltage on the frame can cause serious or lethal electrical shock.
Explosive hazards
Adamaged CRT face or abulging capacitor can cause serious injury.
Mechanical hazards
Loose or missing items (for example, nuts and screws) can cause serious
injury.
Perform the following steps to inspect each SAN Volume Controller node for
unsafe conditions. If necessary, see any suitable safety publications.
1. Turn off the SAN Volume Controller and disconnect the power cord.
2. Check the frame for damage (loose, broken, or sharp edges).
3. Check the power cables using the following steps:
a. Ensure that the third-wire ground connector is in good condition. Use a
meter to check that the third-wire ground continuity is 0.1 ohm or less
between the external ground pin and the frame ground.
b. Ensure that the power cord is the appropriate type, as specified in the parts
listings.
c. Ensure that the insulation is not worn or damaged.
4. Check for any obvious nonstandard changes, both inside and outside the
machine. Use good judgment about the safety of any such changes.
xii IBM System Storage SAN Volume Controller: Installation Guide

5. Check inside the SAN Volume Controller for any obvious unsafe conditions,
such as metal particles, contamination, water or other fluids, or marks of
overheating, fire, or smoke damage.
6. Check for worn, damaged, or pinched cables.
7. Ensure that the voltage that is specified on the product-information label
matches the specified voltage of the electrical power outlet. If necessary, verify
the voltage.
8. Inspect the power supply assemblies and check that the fasteners (screws or
rivets) in the cover of the power-supply unit have not been removed or
disturbed.
9. Before connecting the SAN Volume Controller to the SAN, check the
grounding.
External machine check
Ensure that you perform an external machine check before you install the SAN
Volume Controller.
Perform the following steps to conduct an external machine check:
1. Verify that all external covers are present and are not damaged.
2. Ensure that all latches and hinges are in the correct operating condition.
3. If the SAN Volume Controller is not installed in arack cabinet, check for loose
or broken feet.
4. Check the power cord for damage.
5. Check the external signal cable for damage.
6. Check the cover for sharp edges, damage, or alterations that expose the internal
parts of the device.
7. Correct any problems that you find.
Internal machine checks
Ensure that you perform an internal machine check before you install the SAN
Volume Controller.
Perform the following steps to conduct the internal machine check:
1. Check for any non-IBM changes that might have been made to the machine. If
any are present, obtain the “Non-IBM Alteration Attachment Survey,” form
number R009, from the IBM branch office. Complete the form and return it to
the branch office.
2. Check the condition of the inside of the machine for any metal or other
contaminants, or any indications of water, other fluid, fire, or smoke damage.
3. Check for any obvious mechanical problems, such as loose components.
4. Check any exposed cables and connectors for wear, cracks, or pinching.

Inspecting the UPS for unsafe conditions
Ensure that you take the time to inspect the uninterruptible power supply (UPS)
for unsafe conditions.
Consider the following conditions and their potential safety hazards:
Electrical hazards (especially primary power)
Primary voltage on the frame can cause serious or lethal electrical shock.
Explosive hazards
Abulging capacitor can cause serious injury.
Mechanical hazards
Loose or missing items (for example, nuts and screws) can cause serious
injury.
Use caution when working in apotential safety hazard that is not covered in the
safety checks. If unsafe conditions are present, determine how serious the hazards
are and whether you can continue before you correct the problem.
Using the following inspection checklist as aguide, inspect the UPS for unsafe
conditions. If necessary, see any suitable safety publications.
1. If any equipment has been damaged during the shipment, keep the shipping
cartons and packing materials.
2. Perform the following steps to file aclaim for the shipping damage:
a. File with the carrier within fifteen days of receipt of the equipment.
b. Send acopy of the damage claim within fifteen days to your service
support representative.
Emergency power-off event
The SAN Volume Controller and each uninterruptible power supply (UPS) support
emergency power-off (EPO) shutdowns.
In the event of aroom EPO shutdown, the 2145 uninterruptible power supply-1U
(2145 UPS-1U) automatically shuts down within five minutes of the input power
being removed. When the 2145 uninterruptible power supply (2145 UPS) detects a
loss of input power, this power loss is reported to the SAN Volume Controller,
which completes the process of shutting down the output from the within five
minutes.
Attention: If an EPO event occurs and the 2145 UPS is not connected to at least
one operational SAN Volume Controller, you must unplug the output cables of the
2145 UPS to remove output power from the UPS.
Checking the safety labels on the SAN Volume Controller
Before you install, use, or service the SAN Volume Controller, you must ensure
that you understand the safety labels.
1. Locate the following labels for the SAN Volume Controller:
