Powering On the Appliance Step 1
Step 2
Verify power status by looking at the Power Status LED on the front panel (see Figure 1-5): •
Off—The appliance is not receiving power. Check the power cord connections and the power source of the facility.
•
Amber—The appliance is in standby power mode. Power is supplied only to the service processor and some motherboard functions.
•
Solid green—The appliance is in main power mode. Power is supplied to all appliance components.
If the Power Status LED is blinking green, press and release the Power button to put the appliance in main power mode.

Shutting Down and Powering Off the Appliance Tip
If you have ordered an appliance with power supply redundancy (at least two power supplies), you do not have to power off the appliance to replace a power supply because they are hot-pluggable. The appliance hard drives are also hot-pluggable. The appliance can run in two power modes: •
Main power mode—Power is supplied to all appliance components and any operating system on your hard drives can run.
•
Standby power mode—Power is supplied only to the service processor and the cooling fans. It is safe to power off the appliance from this mode.
You can invoke a graceful shutdown or an emergency shutdown (hard shutdown) by using either of the following methods: •
Remote shut down using the CIMC management interface. See the Cisco Media Delivery Engine Administration Guide for information about remotely powering down the appliance.
•
Pressing the Power button on the appliance front panel.
To use the Power button to shut down your system: Step 1
Check the color of the Power Status LED (see the “Front Panel LEDs” section on page 1-5). •
Green LED
•
Amber LED
Green LED
A green LED indicates that the appliance is in main power mode and must be shut down before it can be safely powered off. Go to Step 2. Step 2
Caution
Invoke either a graceful shutdown or a hard shutdown:
To avoid data loss or damage to your operating system, you should always invoke a graceful shutdown. •
Graceful shutdown—Press and release the Power button. The operating system will perform a graceful shutdown and the appliance goes to standby mode, which is indicated by an amber Power Status LED.
•
Hard shutdown—Press and hold the Power button for 4 seconds to force the main power off and immediately enter standby mode.
Amber LED
An amber LED indicates that the appliance is already in standby mode and can be safely powered off. Disconnect the power cords from the power supplies in your appliance to completely power off the appliance.

Installing or Replacing Components Warning
Only trained and qualified personnel must be allowed to install, replace, or service this equipment. Statement 1030
Warning
This unit might have more than one power cord. To reduce the risk of electric shock, disconnect the two power supply cords before servicing the unit. Statement 14
Caution
Tip
When handling appliance components, wear an ESD strap to avoid damage.
You can press the Locator button on the front panel to turn on a flashing Locator LED on the appliance front and rear panels. This button allows you to locate the specific appliance that you are servicing when you go to the rear of the rack. See the “Status LEDs” section on page 1-5 for locations of the LEDs. Before You Begin
The following situations indicated that a Cisco ECDS disk needs to be replaced: •
The disk has failed on the UCS.
•
SMART detection has indicated that disk failure is imminent but no LED indications are present, so it is unclear which disk should be replaced.
In either case, the disk must be marked as “bad” prior to removing it. When a new disk is installed, you must then mark it as “good” and reboot the device for the system to recognize the new disk. Troubleshooting Tip
If your system reports a newly installed disk as “Not Used,” make sure you have marked the new disk “good” with the CLI after installing it. See the following sections to manage your system according to the number of slots/disks you are using: •

Managing the Cisco MDE 3125 with up to Eight Disks With the LSI MegaRAID 9266-8i 8-port internal controller, the hard disks are smaller and the optical (DVD/CD-ROM) drive is removed. The Cisco MDE 3125 supports two Gbps with 5000 concurrent connections and can hold up to eight 2.5-inch hard drives or solid state drives. The drive-bay numbering is shown in Figure 3-1.

Observe these drive population guidelines for optimum performance: •
When populating drives, add drives to the lowest-numbered bays first.
•
Keep an empty drive blanking tray in any unused bays to ensure proper air flow.
•
You can mix hard drives and SSDs in the same server (the LFF version of the server does not support SSDs). However, You cannot configure a logical volume (virtual drive) that contains a mix of hard drives and SSDs. That is, when you create a logical volume, it must contain all hard drives or all SSDs.

d.
Press the ejector lever flat until the lock clicks into place.
Mark the new disk “good” by entering the following command: #disk mark good
Step 5
Reboot the MDE device. The new disk will be configured during the boot-up process. If the disk replaced is in slot 1 or slot 2, the system will take some extra time to complete the RAID re-configuration process automatically. Use the show disks raid-state command to check RAID status.

Installing Power Supplies Note
The Cisco MDE 3100 Series has redundant power supplies. You do not have to completely power off the appliance to replace power supplies because they are hot-pluggable. To replace a power supply:
Step 1
Remove a power supply or a blank panel from an empty bay: a.
Do one of the following: – If your appliance has only one power supply, shut down and power off the appliance as
described in the “Shutting Down and Powering Off the Appliance” section on page 3-2. – If your appliance has two power supplies, shut down the appliance as described in the “Shutting
Down and Powering Off the Appliance” section on page 3-2. Remove the power cord from the power supply that you are replacing.
c.
Push the release lever toward the center of the power supply and pull on the power supply handle to disengage it from the backplane (see Figure 3-4).
d.
Remove the power supply from the bay.
Install a new power supply: a.
Insert the new power supply into the bay and push it in until the release lever clicks and locks.
b.
Replace the power cord to the new power supply.
c.
Press the Power button to return the appliance to main power mode.

Log on to the Cisco MDE using the CIMC connect host command. The following message is displayed: The software component on your flash device appears to be different from what should be installed
Step 15
Enter the show disk details command to make sure all hard disk drives (HDDs) are operational and that the Cisco Content Delivery Network file system (CDNFS) size is correct. See also the “Disk Detail Examples” section on page 3-13.
Step 16
Enter the show hardware command to make sure the RAM size is correct and to verify that the Serial Number matches the number in the CIMC.
Step 17
Restore your original configuration by manually retyping the saved configuration line by line or run the setup program, which assists with initial configuration.
Step 18
Verify the current running configuration by using the show running-config command. CDM# show running-config
Step 19
To sync the operating system (OS) with the USB, use the copy http install command to install upgrade .bin software: a.
Obtain the Cisco ECDS software upgrade .bin file (for example, ECDS-X.x.x.x-K9.bin)
b.
Copy this file onto an HTTP server that can be reached from the Cisco ECDS.
c.
Install .bin software using the following command: copy http install ECDS-X.x.x.x-K9.bin [port]
d.
Tip
Reload using the reload command.
After the reload, you should no longer receive the “...software component on your flash device appears to be different from what should be installed” message.

Disk hot plugin is not supported. When a disk is taken out or damaged, the show alarm, show disk raid-state, and show disk detail CLI report the missing or damaged disk. The platform does not recover a disk when it is reinserted. In general good disks are only “reusable” after reload.
