A data-center technician is dispatched to troubleshoot a blade server whose remote management controller has become unresponsive. The technician wheels a crash cart equipped with a USB keyboard, USB mouse, and VGA monitor to the rack. The front of the blade server exposes only a proprietary multi-pin connector-no standard VGA, USB, or serial ports are visible. Which of the following additional items will the technician MOST likely need to obtain before the crash cart can be used for local console access to the blade?
An RJ-45 rollover cable to connect the crash cart to the chassis management module
An LC multimode fiber patch cord for the blade's mezzanine network interface
The vendor-supplied KVM breakout dongle that converts the blade's local-console connector to VGA and USB
A QSFP+ transceiver that matches the chassis fabric interconnect
Blade servers do not include built-in keyboard, video, or mouse ports. Vendors ship a small KVM or "SUV" dongle that plugs into the blade's local-console connector and breaks out to VGA plus USB (and sometimes serial) leads. Without that dongle, the technician's crash-cart monitor and input devices have nowhere to connect, so the POST screen and BIOS setup remain inaccessible.
An RJ-45 rollover cable would reach only a serial service port; it cannot pass VGA video or USB HID signals.
LC fiber jumpers and QSFP+ modules are used for network connectivity, not for console I/O. Therefore, securing the vendor-specific KVM dongle is the required step to make the crash cart functional for this scenario.
