Catalyst 8540 MSR ATM OC-48c Super Port Adapter Modules

The Catalyst® 8540 MSR ATM OC-48c Super Port Adapter Modules are ideal for supporting high-speed ATM backbone applications. The OC-48c Super Port Adapter Modules are supported by the Catalyst 8540 MSR, a high-end multiservice switch that integrates L3 and ATM switching in one high-performance platform.

Module Description

The ATM OC-48c super port adapter modules are dual-slot, full width interface modules available for the Catalyst 8540 MSR. The OC-48c long-reach (LR) version allows customers to connect sites with link spans of a maximum of 80Km, while the OC-48c intermediate-reach (IR) version of the OC-48c interface allows customers to connect sites with link spans up to 15Km. The following five OC-48c versions are available:

  • C85MS-2F-OC48LR: Two-port OC-48c SMF-LR
  • C85MS-1F4S-OC48LR: One-port OC-48c SMF-LR + four-port OC-12c SMF-IR
  • C85MS-2F-OC48SS: Two-port OC-48c SMF-IR
  • C85MS-1F4S-OC48SS: One-port OC-48c SMF-IR + four-port OC-12c SMF-IR
  • C85MS-1F4M-OC48SS: One-port OC-48c SMF-IR + four-port OC-12c MMF

Indicators

Status LED, one for OC-48c, and one for OC-12c:

  • Green indicates that the board is functioning fine.
  • Red indicates there is a fault on the board.
  • Yellow indicates that the board has not yet initialized.

Port LEDs

Link: Green, Carrier/Signal is detected by the optics. Off indicates no signal.

TX LED

  • Green blinking indicates that cells are being transmitted at low rate.
  • Steady Green indicates cell transmitted at high rate.
  • Red indicates AIS.
  • Yellow indicates loopback state.

RX LED

  • Blinking green indicates that cells are being received at a low rate.
  • Steady Green indicates cell received at high rate.
  • Red indicates far end alarm.
  • Yellow indicates a loopback state.

Hardware

The physical dimensions of the board are as follows:

  • Width: 15.35 inches (38.9 cm)
  • Length: 16.76 inches (42.5 cm)
  • Height: 2.37 inches (6 cm)
