3Eachserver has a blank plastic asset tag that pulls out of the front panel, provided so you can add your own asset tracking label without interfering with the
intendedair flow.
LEDs
TheLED indicators indicate whether the blade server is in active or standby mode, the status of the network
link,the over all health of the blade server, and whether the server is set to give a flashing blue beaconing
indication.See Interpreting LEDs, onpage 25 for details.
Theremovable hard disks also have LEDs indicating hard disk access activity and hard disk health.
Buttons
TheReset button is just inside the chassis and must be pressed using the tip of a paper clip or a similar item.
Holdthe button down forfive seconds and then release it to restart the server if other methods of restarting
arenot working.
Thebeaconing function for an individual server may get turned on or off by pressing the combination button
andLED. See Interpreting LEDs, on page25 for details.
Thepower button and LED allows you to manually take a server temporarily out of service but leave it in a
statewhere it canbe restarted quickly.
Connectors
Aconsole port gives a direct connection to a blade server to allow operating system installation and other
managementtasks to be done directly rather than remotely. The port uses the KVM dongle device included
inthe chassisaccessorykit. SeeKVM Cable, on page 69 for more information.
Adapter Cards
Dependingon the model of server in question, one to three adapter cards will reside in each blade server,
providingfailover connectivity to each FEX in the chassis.The following models are available,and others
arereleased on anongoing basis:

Cisco UCS Virtual Interface Card 1280

TheCisco UCS Virtual Interface Card 1280 (UCS-VIC-M82-8P) is an eight-port 10 Gigabit Ethernet, Fibre
Channelover Ethernet(FCoE)-capablemezzanine card designed exclusivelyforCisco UCSB-SeriesBlade
Servers.The card enables a policy-based, stateless, agile server infrastructure that can present up to 256 PCIe
standards-compliantinterfaces to the host that can be dynamically configured as either networkinterface cards
(NICs)or host bus adapters (HBAs). In addition, the Cisco UCS Virtual Interface Card 1280 supports Cisco
VirtualMachine Fabric Extender (VM-FEX) technology, which extends the Cisco UCS Fabric Interconnect
portsto virtual machines, simplifying server virtualization deployment.

Cisco UCS M81KR Virtual Interface Card

TheCisco UCS M81KR Virtual Interface Card is a virtualization-optimized Fibre Channel over Ethernet
(FCoE)adapter card. The virtual interface card is a dual-port 10 Gigabit Ethernet adapter card that supports
