PRODUCT OVERVIEW

Preface The 3Com Switch 8800 Family of Routing Switches (referred to as the Switch 8800

Family) are intelligent, multi-layer modular LAN switches and are ideal for enterprise environments where non-stop availability of critical applications and the highest performance, security, and granular control are required. The Switch 8800 Family delivers high density Gigabit and 10 Gigabit switching in an integrated chassis platform. Built-in support for IPv6, MPLS, Power over Ethernet (PoE), and

1.44 Tbps backplane capacity ensures unprecedented investment protection.

Resilient Layer-3 routing, hot-swap modules, and redundant power, along with sub one-second fabric fail over on the Switch 8800, ensure (24 x 7) availability to support the most demanding enterprise core and campus environments. Advanced Quality of Service features such as bandwidth management and packet classification optimize quality for real-time voice and video applications. Intrusion prevention security capabilities such as IEEE 802.1X Network Login and Access Control Lists ensure that only authorized users can access network resources.

The Switch 8800 is focused on delivering functionality towards the higher end of the large Enterprise, with a 4-port 10 Gigabit Module, high density 48-port Gigabit Modules, as well as a group of Advanced Modules with support for larger routing tables and/or MPLS. Power over Ethernet (PoE) is built into all Switch 8800s.

Application modules for the Switch 8800 provide the flexibility to add a firewall, IPsec encryption, network monitoring with NetFlow, and Layer 2 VPN networking using Virtual Private LAN Service (VPLS) by simply adding a module to the chassis.

Backplane The backplane of the Switch 8800 Family allows high-speed data exchange

between fabrics and I/O modules, as well as the exchange of various management and control signals in the system.

Functions

The following are the main functions of the backplane:

■ Providing communication channels for signal exchange between boards

■ Supporting board hot-swapping

■ Supporting auto-discovering boards in slots

■ Connecting PSUs, distributing power and providing monitor channels to

various components (PSUs, fabrics and I/O modules) in the chassis.

General Architecture 13

The Switch 8807 uses a passive backplane, which provides five I/O module interfaces, two fabric interfaces, one fan interface, and three -48V power interfaces (two for PSUs and one for PoE entry module).

■ Switch 8810

The Switch 8810 uses a passive backplane, which provides eight I/O module interfaces, two fabric interfaces, one fan interface, and three -48V power interfaces (two for PSUs and one for PoE entry module).

■ Switch 8814

The Switch 8814 uses a passive backplane, which provides 12 I/O module interfaces, two fabric interfaces, two fan interfaces, and three -48V power interfaces (two for PSUs and one for PoE entry module).

■ The Switch 8800 Family supports AC power inputs.

■ The Switch 8800 Family supports 1+1 power supply redundancy.

■ The PSUs of the Switch 8800 Family are online-swappable.

The Switch 8800 Family supports AC power inputs. The power frame is at the bottom of the chassis, with a height of 3U. In the same slot, you can insert an AC PSU. The power frame is in different compartment from the functional board frame and connected to the latter with cables, which are routed along the back of the chassis. The power supply is cooled by built-in fans of the PSUs, which draw air into the chassis from the front and exhaust air out of the chassis from the back.

PoE Power Supply The Switch 8800 Family supports Power over Ethernet (PoE). With this feature, a

Switch 8800 Family switch equipped with an external PoE power supply and PoE-capable modules can deliver 48 VDC to its remotely powered devices (PDs, such as IP phones, WLAN APs and network cameras) through twisted pairs.

■ The Switch 8800 Family can supply power to remote PDs through the Ethernet

electrical ports on the I/O modules. Each I/O module can simultaneously supply power to up to 48 PDs with the maximum distance of 100 m (328.1 feet).

■ Each Ethernet port can deliver up to 15.4 W to its PD.

PoE entry area

The PoE-supported Switch 8807/Switch 8810/Switch 8814 chassis has a PoE entry area between the two power supply units. You can insert a PoE 3C17510 Switch 8800 PoE Entry Module into this area, and connect this module to a 3C17509 Switch 8800 External PoE Power Rack so as to import the output power of the External Power Rack unit.

External PoE Power Rack (3C17509)

The Switch 8800 External Power Rack is available for the Switch 8807, Switch 8810, and Switch 8814. The External Power Rack has three AC inputs and one DC outputs.

Figure 8 shows its front panel.

The external PoE power system supports 2+1 redundancy and online-swapping of PSUs.

To implement the PoE function on the Switch 8800 Family, PoE-capable interface module is required. There are two modules are PoE-capable:

■ 3C17528 Switch 8800 48-port 10/100/1000BASE-T

■ 3C17532 Switch 8800 48-port 10/100/1000BASE-T Access

Both of these I/O Modules are PoE-capable, and will function with the addition of a 3C17529 PoE Option (PoE DIMM Module).

MBUS Introduction

The MBUS is a service-independent maintenance and test bus. No service traffic goes through the MBUS. The shutdown and reset of the MBUS does not affect the services on the switch, and faults that have occurred on modules do not affect the MBUS.

The external PoE power system for the Switch 8800 Family only supports the

Normal state

Abnormal state Abnormal reason

fuse

trouble

under-voltage or over-voltage input, under-voltage or over-voltage output, or PSU fault

Through the MBUS, the system instructs the MBUS modules on individual cards to power on/off the cards one by one in turn, thus prevent power surging. The MBUS module software must support online upgrade.

16 CHAPTER 1: PRODUCT OVERVIEW

Role and function

The MBUS system is powered by 5 V from the MBUS on the fabric. The 5 V power on the two fabrics are redundant to each other.

Each MBUS module is attached to the MBUS, which contains two control lines: MBUS0 and MBUS1.

Each card has an independent MBUS module, those on the fabrics are primary MBUS modules, and those on application modules are secondary MBUS modules.

When the fabrics operate in redundancy mode, the MBUS module on the active fabric is the active module, and the one on the standby fabric is the standby module.

The MBUS uses a controller area network (CAN) bus as its control bus, that uses the 1:1 hot backup and transfers control information at 1 Mbps.

Fan Tray ■ The Switch 8807 uses one 25 W fan tray, which contains four 120 x 120 x 25.4

mm (4.7 x 4.7 x 1.0 in.) axial fan units. The fans can be governed in two modes: fabric-controlled or temperature-controlled. They operate at -48 VDC supplied from the backplane.

■ The Switch 8810 uses one 35 W fan tray, which contains six 120 x 120 x 25.4

mm (4.7 x 4.7 x 1.0 in.) axial fan units. The fans can be governed in two modes: fabric-controlled or temperature-controlled. They operate at -48 VDC supplied from the backplane.

■ The Switch 8814 uses two 25 W fan trays, each of which contains four 120 x

120 x 25.4 mm (4.7 x 4.7 x 1.0 in.) axial fan units (and totally eight for the two fan trays). The fans can be governed in two modes: fabric-controlled or temperature-controlled. They operate at -48 VDC supplied from the backplane.
