Line Card Redundancy - Cisco ASR 5000 Installation Manual

Line Card Redundancy

Line Card Type
Ethernet 10/100 (FLC2)
Ethernet 1000 (GLC2)
Quad Gig-E (QGLC)
10 Gigabit Ethernet Card
(XGLC)
Optical (ATM) (OLC2)
Channelized (CLC2)
Line Card Redundancy
To optimize network efficiency and minimize down time, the system supports 1:1 redundancy for OLC2s,
CLC2s, FLC2s, GLC2s, and QGLCs.
With the exception of the XGLC, line cards are installed in the half-height slots at the rear of the chassis. This
design allows two Ethernet or two Optical (ATM) or two Channelized line cards directly behind (one top,
one bottom) every packet processing card that normally operates in active mode.
When two line cards are installed, the card in the upper-rear chassis slot is automatically the active card. The
card in the lower-rear chassis slot is automatically placed in standby mode. In the event that the active card
experiences a failure, the system automatically migrates traffic to the standby card in the lower slot.

76
Chassis Slot Number Description
17 through 23, 26 Resides directly behind its corresponding packet
through 39, or 42 processing card. Each packet processing card can
through 48 support up to two FLC2s. The active card is installed
in the upper rear chassis slot. The redundant card is
installed in the lower rear chassis slot.
17 through 23, 26 Resides directly behind its corresponding packet
through 39, or 42 processing card. Each packet processing card can
through 48 support up to two GLC2s. The active card is installed
in the upper rear chassis slot. The redundant card is
installed in the lower rear chassis slot.
17 through 23, 26 Resides directly behind its corresponding packet
through 39, or 42 processing card. Each packet processing card can
through 48 support up to two QGLCs. The active card is
installed in the upper rear chassis slot. The redundant
card is installed in the lower rear chassis slot.
17 through 23 and 26 Resides directly behind its corresponding packet
through 32 processing card. The XGLC is a full-height line card
that occupies the upper and lower slots in the ASR
5000.
17 through 23, 26 Resides directly behind its corresponding packet
through 39, or 42 processing card. Each packet processing card can
through 48 support up to two OLC2s. The active card is installed
in the upper rear chassis slot. The redundant card is
installed in the lower rear chassis slot.
7 through 23, 26 Resides directly behind its corresponding packet
through 39, or 42 processing card. Each packet processing card can
through 48 support up to two CLC2s. The active card is installed
in the upper rear chassis slot. The redundant card is
installed in the lower rear chassis slot.
