Equipment Rack Specifications
Cisco Systems has tested the Cisco CRS-1 8-slot line card chassis to Cisco internal mechanical design
verification testing and electrical design verification testing in an Enclosure Systems Worldwide ESW
27 rack (part
number F-01941-01). This finding is neither an endorsement nor recommendation for any
particular rack product. The Cisco
CRS-1 product documentation will be updated with additional
information. Use this information for planning only. Consult your Cisco account representative for
additional details.
Note Proper grounding is also required at the site to
ensure that equipment is not damaged by
lightning or power surges.
Power Redundancy (2N)
DC Three “A” battery plant feeds required for one PDU,
and three “B” battery plant feeds required for the other
PDU.
AC (Delta or Wye 3-phase) Two independent Delta or Wye 3-phase power sources
required, one for each PDU.
DC Input
Nominal input voltage –48 VDC North America
–54 VDC Telco (RBOC)
–60 VDC International
(range –40.5 to –75 VDC)
Input current 60 A at –48/–60 VDC (nominal voltage)
66 A at –40.5 VDC (low voltage extreme)
AC Input, Delta 3-phase
