CAUTION
Disassembling any part of the power supply voids the part warranty and regulatory certifications. There
are no user-serviceable parts inside the power supply. The cooling system relies on pressurized air, do
not leave either of the power supply slots empty longer than two minutes when the Switch or SAN Router
is operating. If a power supply fails, leave the power supply in the Switch or SAN Router until it can be
replaced. Maintain both power supplies in operational condition to provide redundancy.
Table 1 on page 5 describes the power supply status LED colors, behaviors, and actions required, if any.
Time Required
Replacing a power supply in the Switch or SAN Router should require less than two minutes to complete.
Items Required
The following items are required to replace a power supply:
•New power supply
•Phillips-head screwdriver #1
TABLE 1 Power supply status LED behavior, description, and required actions

Replacing a Power Supply
Perform the following steps to replace a power supply unit in the Switch or SAN Router.
1. To leave the Switch or SAN Router in service while replacing a power supply, verify that the other power supply
(the one not being replaced) has been powered on for at least four seconds and has a steady green LED.
2. Power off the power supply by pressing the AC power switch to the “0” symbol. See Figure 1 for the location of
the AC power switch.
3. Unplug the power cord from the power supply that is being replaced.
4. Use a Phillips-head screwdriver to unscrew the captive screw on the power supply.
5. Remove the power supply from the chassis by pulling the handle on the power supply out, away from the
chassis.
6. Install the new power supply in the chassis.
CAUTION
Do not force the installation. If the power supply does not slide in easily, ensure that the power supply is
correctly oriented before continuing.
a. Orient the power supply as shown in Figure 2, with the AC power switch on the left. (The actual appearance
of the Switch or SAN Router may differ from this illustration but the locations are correct.)
b. Gently push the power supply into the chassis until it is firmly seated.
c. Secure the power supply to the chassis by screwing in the captive screw using the Phillips-head screwdriver.
7. Plug the power cord in to the power supply and power on the Switch or SAN Router by pressing the AC power
switch to the “1” symbol.
8. Verify that the LED on the new power supply displays a steady green light while the Switch or SAN Router is
operating (see Table 1 on page 5). If the LED is not a steady green, ensure that the power supply is securely
installed and seated properly.
