ED-64M Director Operating Features
Two fiber-optic transceiver types are available:
◆
Shortwave laser — Provides connections for transferring data
over short distances (up to 300 meters at 2 Gb/s and 500 meters at
1 Gb/s) through 50-micron or 62.5-micron multimode fiber.
Transmission speeds affect the distance capabilities of multimode fiber.
Refer to Planning Cabling in the
Connectrix V.6.03 2 Gb/s Enterprise
Storage Network System Planning Guide, P/N
..
◆
Longwave laser — Provides connections for transferring data
over long distances (up to 20 kilometers) through 9-micron
single-mode fiber.
The director provides chassis slots for up to 16 UPM cards (64 ports
total). An UPM card is a concurrent FRU and can be added or
replaced while the director is powered on and operating.
Power Supplies
Redundant, load-sharing power supplies step down and rectify
facility input power to provide 48 VDC power to director FRUs. The
power supplies also provide overvoltage and overcurrent protection.
You can replace either power supply while the director is powered on
and operational.
Each power supply has two separate backplane connections for
different AC power sources. The power supplies are input rated up to
264 VAC.
RFI Shield
The RFI shield covers and provides RFI protection for all rear-access
FRUs except the input power module. The RFI shield can be removed
or replaced while the director is powered on and operating.
Input Power Module
The input power module is located at the bottom rear of the director.
The module is a nonconcurrent FRU; the director must be powered
off before scheduled removal and replacement. The module provides:
◆
Two single-phase AC power connectors for connection to the
EC-1200 AC power distribution system. Each connector is input
rated at up to 264 VAC.
◆
A power switch (circuit breaker) that controls AC power
distribution to both power supplies. The breaker is set manually,
or is automatically tripped by internal software if thermal sensors
indicate the director is overheated.
