DIMM slots for CPU 3

mLOM card

This slot is shown in Cisco UCS Manager as "Adapter

1" but the BIOS lists it as "mLOM." The VIC 1240 is a

type of adapter with a specific footprint that can only be

used in this slot.

Supercap for flash-backed write cache

The flash-backed write cache feature is not supported

at the initial server release.

• A squeeze-to-remove retaining clip is provided to secure the internal USB flash memory, the clip

Note

must always be securely fastened when the flash memory is in use. Third party memory that will

not fit in the clip should not be used.

• Use of this server may require an upgrade to the FEX in the chassis. The 2104XP fabric extender is

not compatible when any Cisco-certified adapter is installed in slot 1 or slot 2. If a VIC 1240 modular

LOM card is installed, you will have connectivity through the mLOM but other adapters will not be

recognized.

Diagnostics Button and LEDs

At blade start-up, POST diagnostics test the CPUs, DIMMs, HDDs, and adapter cards, and any failure notifications are sent to UCS

Manager. You can view these notifications in the Cisco UCS Manager System Error Log or in the output of the show tech-support

command. If errors are found, an amber diagnostic LED also lights up next to the failed component. During run time, the blade BIOS

and component drivers monitor for hardware faults and will light up the amber diagnostic LED as needed.

LED states are saved, and if you remove the blade from the chassis the LED values will persist for up to 10 minutes. Pressing the

LED diagnostics button on the motherboard causes the LEDs that currently show a component fault to light for up to 30 seconds for

easier component identification. LED fault values are reset when the blade is reinserted into the chassis and booted, and the process

begins from its start.

If DIMM insertion errors are detected, they may cause the blade discovery process to fail and errors will be reported in the server

POST information, which is viewable using the UCS Manager GUI or CLI. DIMMs must be populated according to specific rules.

The rules depend on the blade server model. Refer to the documentation for a specific blade server for those rules.

Faults on the DIMMs or adapter cards also cause the server health LED to light solid amber for minor error conditions or blinking

amber for critical error conditions.

DIMM slots for CPU 4

Adapter card

This slot is shown in Cisco UCS Manager as "Adapter

2," but is shown in the BIOS as "Mezz 1." Mixing

adapter types is supported.
