Cisco UCS B22 Blade Server Installation and Service Note

Removing a Blade Server Cover

Internal Components

Figure 9 calls out the various components within the blade server.

Note Use of this server may require an upgrade to the IOM in the chassis. This server only supports third

generation adapter cards, which have features requiring a Cisco 2204 or 2208 IOM, and are not

backward compatible with the Cisco 2104 IOM.

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 System Error Log or in

the output of the show tech-support command. If errors are found, an amber diagnostic LED will also

light up next to the failed component. During run time, the blade BIOS, component drivers, and OS all

monitor for hardware faults and will light up the amber diagnostic LED for a component if an

uncorrectable error or correctable errors (such as a host ECC error) over the allowed threshold occur.

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 will cause 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.

1. Cisco UCS-USBFLSH-S-4GB= is recommended, but if another USB drive will be used it must be no wider than .8 inches,

and no more than 1.345 inches long in order tp provide needed clearances to install or remove the USB drive.
