Powering On the Appliance
To power on the Cisco MDE 1100 Series appliance:
Step 1 Verify power status by looking at the Power Status LED on the front panel (see Figure 1-3):
•Off—The appliance is not receiving power. Check the power cord connections and the power source of the facility.
•Blinking green—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.
Step 2 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
•Understanding Power Supplies
Understanding Power Supplies
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; the Cisco MDEs are redundant and 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 and 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:
•Use the CIMC management interface. See the Cisco Media Delivery Engine Administration Guide for information about remotely powering down the appliance.
•Use the Power button on the appliance front panel.
Tip To avoid data loss or damage to your operating system, you should always invoke a graceful shutdown of the operating system.
To use the Power button to power off:
Step 1 Check the color of the Power Status LED (see the "Front Panel LEDs" section).
•Green 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.
•Amber indicates that the appliance is already in standby mode and can be safely powered off. Go to Step 3.
Step 2 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 of the operating system.
•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.
•Emergency shutdown—Press and hold the Power button for 4 seconds to force the main power off and immediately enter standby mode.
Step 3 Disconnect the power cords from the power supplies in your appliance to completely power off the appliance.
Installing or Replacing Components
This section describes how to remove and replace Cisco MDE 1100 Series appliance 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
When handling appliance components, wear an ESD strap to avoid damage.
Tip Press the Locator button on the front panel to turn on a flashing Locator LED on the appliance front and rear panels. This button helps you to locate the specific appliance that you are servicing when you go to the rear of the rack. See the "Status LEDs" section for locations of the LEDs.
Before You Begin
Fresh installations, upgrades, and replacements are supported.
The following situations indicated that an 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.
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:

Note Disk hot swap is not supported on MDE-1100 in a four-slot/disk system. Four-disk support is available in ECDS Release 2.5.5 and later releases. Online insertion and removal of hard disks on the
Cisco MDE 1125 is also not supported.
The Cisco MDE 1100 supports SoftRAID (software implementation of RAID1) on SYSFS volumes on Disk 0 and Disk1. With disk expansion, the SoftRAID behavior remains the same while the CDNFS space is expanded.
Figure 3-1 Cisco MDE 1100 Four Slots
Fresh installation properly initializes disks 2, 3, or 4 once they are inserted in the system. Software upgrade also properly initializes the disks (2, 3, 4) inserted in the system, then the extra disk space is properly utilized. Any preexisting contents are preserved with the software upgrade.
Note Disk hot swap is supported in a two slot/disk system.
Managing the Cisco MDE 1125 with up to Four 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 1125 supports 300 Mbps with 1000 concurrent connections and can hold up to four 3.5-inch hard drives.
The drive-bay numbering is shown in Figure 3-2.
Figure 3-2 Drive Numbering, Large Form Factor
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.

Installing Power Supplies
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.
To replace or install a redundant power supply:
Step 1 Remove a power supply or a blanking panel from an empty bay by doing 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.
•If your appliance has two power supplies, shut down the appliance as described in the "Shutting Down and Powering Off the Appliance" section. The power supplies are hot pluggable, so you do not have to completely power off the appliance.
Then follow these steps:
d. Remove the power cord from the power supply that you are replacing.
e. Cisco MDE 1100—Push the release lever toward the center of the power supply or blanking panel and pull on the handle to disengage the supply from the backplane (see Figure 3-5).
Cisco MDE 1125—Grasp the power supply handle while pinching the release lever towards the handle (see Figure 3-6).
f. Pull the power supply out of the bay.
Step 2 Install a new power supply:
a. Cisco MDE 1100—Insert the new power supply into the bay and push it inward until the release lever clicks and locks.
Cisco MDE 1125—Grasp the power supply handle and insert the new power supply into the empty bay. Push the power supply into the bay until the release lever locks.
b. Connect the power cord to the new power supply.
c. Press the Power button to return the appliance to main power mode.
