•Removing Power Supply Modules

Power Supply Modules

The Cisco SFS 7000P and SFS 7000D Server Switches power supply modules are hot-swappable. You can add a second module without powering off a switch. If you have two power supply modules installed, you can remove one of them without removing power from the switch.

Locating the Power Supply Unit

The Cisco SFS 7000P and SFS 7000D Server Switches can have up to two power supply modules. Each power supply module contains a power supply and a fan unit. Both power modules are located at the front of the switch. When facing the front of the switch, the power supply modules are located in the left and right slots of the switch.

Failed Power Supply Modules

The status of a power supply module can be checked using the CLI, the Chassis Manager, or the Element Manager. The available information includes the status, the VPD, the description of the error, or an error code.

If you suspect that a power supply module has failed, check the LEDs and view the status through the Element Manager. For more information about LEDs, see the "Power Supply LEDs" section on page 5-3.

In most cases, vital information can be retrieved from the console port of the management Ethernet port. (See the "Diagnostics" section.)

See the Cisco SFS 7000 Series Product Family Chassis Manager User Guide or Cisco SFS 7000 Series Product Family Element Manager User Guide for more information.

Installing a Power Supply Module

---

Warning Hazardous voltage or energy is present on the backplane when the system is operating. Use caution when servicing. Statement 1034

---

---

Caution Never place your hand inside an empty module bay or anywhere inside the
Cisco SFS 7000P and SFS 7000D Server Switches.

---

---

Caution Unused module bays always should have a switch filler panel over the bay to ensure proper safety, ventilation, and cooling.

---

To insert a power supply module, follow these steps:

---

Step 1 Ground yourself appropriately.

Step 2 Remove the filler panel from the power supply bay with a number 1 Phillips or a slotted screwdriver, if it is still in place. (See Figure 4-1.)

Figure 4-1 Removing a Filler Panel from the Switch

Step 3 Remove the power supply module if one is in place by pulling on the black handle. (See Figure 4-2.)

Figure 4-2 Removing the Power Supply from the Switch

Step 4 Insert the new power supply module into the open slot until it is fully seated. You might need to push the unit with your thumbs to ensure that it is seated completely in the bay.

Step 5 Secure fasteners with a number 1 Phillips or a slotted screwdriver.

Step 6 Check the LEDs to verify the status of the module. (See Figure 4-3 for the location of the LEDs.)

For more information, see the "Power Supply LEDs" section on page 5-3.

Removing Power Supply Modules

---

Caution Do not remove the power supply module without first removing the screws. Use a number 1 Phillips or a slotted screwdriver.

---

To remove a power supply module, follow these steps:

---

Step 1 Make sure you have a number 1 Phillips or a slotted screwdriver to disengage the fasteners.

Step 2 Ground yourself appropriately.

---

Caution Never place your hand inside an empty card or module bay or anywhere inside the
Cisco SFS 7000P and SFS 7000D Server Switches.

---

Step 3 Locate the power supply module that you want to remove.

If you have two power supply modules installed, you can remove one of them without removing power from the switch.

Step 4 Unscrew the fasteners that hold the power supply module in place. (See Figure 4-4.)

Step 5 Pull the unit from the bay.

Step 6 Install the filler panel in place of the power supply module, or install a new power supply module. If you are installing a new power supply module, see the "Installing a Power Supply Module" section.

---

Caution Never operate the device without a filler panel or power supply module in place because the device might overheat.
