Components Description
PCIe carrier/cards Six hot-plug switched PCIe 8x card slots. Slots 1 and 4
can support full-length cards. Each PCIe card is housed
in an individual carrier.
Cell ID An LED that is lit when the ID button on the
EXPRESSSCOPE® Monitor is pressed. Press the cell
ID button on the rear of the cell to turn off the light.
Partition USB ports Two universal serial bus (USB) 2.0 ports.
Management serial port A 9-pin serial port for the management board.
Partition serial port A 9-pin serial port for the operating system.
Maintenance LAN port An RJ45 port that provides a 10/100 Mbps Ethernet
network connection to the maintenance LAN.

used in high-voltage configurations. Each power supply
has its own AC power cord.
Interconnect cable connectors High-speed serial interface and management LAN
connections between the cells in configurations with
two or more cells.
