Director 2/64 Installation Guide
Cable Management Assembly
The cable management assembly positioned at the front of the director provides
routing for Ethernet cables attached to CTP2 cards and fiber-optic cables attached
to director ports. The assembly rotates up to provide front access to the redundant
power supplies.
The cable management assembly is supplied with rack mount kits for the
9000/10000/11000 and M-Series racks only.
Power Supplies
The Director 2/64 uses redundant, load-sharing power supplies which step down
and rectify facility input power to provide 48-VDC power to Director FRUs. The
power supplies also provide over-voltage and over-current protection. Either
power supply can be replaced while the switch is powered on and operational.
Each power supply has a separate backplane connection to allow for different AC
power sources.
The power supplies are input rated at 85 to 264 VAC. The faceplate of each power
supply provides the following status LEDs:
■
A green PWR OK LED turns O
N
if the power supply is operational and
receiving AC power.
■
An amber FAULT LED turns O
N
if the power supply fails.
■
An amber TEMP LED turns O
N
if the power supply shuts down due to an
over temperature condition.
■
An amber I LIM LED turns O
N
if the power supply is overloaded and
operating at the current limit (15.6 A).
Power supply requirements are listed in
Appendix B

UPM Card
Each Universal Port Module (UPM) card provides four full-duplex generic ports
(G_Ports) that transmit or receive data at 1.063 or 2.125 gigabits per second
(Gbps). G_Port functionality depends on the type of cable attachment. UPM cards
use Non-Open Fiber Control (NOFC) Class 1 laser transceivers that comply with
Section 21 of the Code of Federal Regulations (CFR), Subpart J as of the date of
manufacture.
